Довольно часто бывает так, что радиаторы отопления не вписываются в интерьер помещения. В этом случае не остается иного выхода, чем закрыть батареи отопления. С этой целью используются декоративные экраны – как они выглядят, можно посмотреть на фото.

Особенности применения декоративных экранов

Выбирая, чем закрыть радиаторы отопления, многие люди делают ошибку, обращая внимание исключительно на внешний вид экранов. И зачастую это приводит к снижению эффективности отопления, так как не все изделия позволяют воздуху беспрепятственно поступать к прибору.

Разумеется, экраны должны выполнять свое основное предназначение – скрывать трубы, старые батареи. Но, выбирая из нескольких вариантов, нужно отдать предпочтение именно тому, который не снизит эффективность обогрева помещений.

Чем закрыть батареи отопления

Существует несколько способов, как скрыть радиатор отопления. Но в любом случае, экран должен позволять легко получить доступ к батарее при неисправностях и не мешать нормальному теплообмену.

Радиаторы прогревают помещение, используя два способа передачи тепла. Подходя к горячей батарее, можно почувствовать идущий от нее жар. Это происходит из-за того, что тепловая энергия передается окружающим предметам с помощью инфракрасного излучения. Сама же атмосфера в помещении равномерно прогревается благодаря конвекционным потокам, смешивающим холодный воздух с теплым.

Выбирая защитный экран, нужно учитывать, что любой из них ухудшает обмен теплом между помещением и радиатором. Чем больше сплошная поверхность такого изделия, тем хуже будет прогреваться комната. Поэтому, решая, чем закрыть старые батареи, нужно обращать внимание на модели, которые не будут препятствовать нормальному теплообмену. Кроме того, экраны должны легко сниматься, чтобы можно было при необходимости получить доступ к радиатору.

Обслуживание и устранение неисправностей

В системах централизованного отопления в качестве теплоносителя выступает обычная техническая вода, чистота которой далека от идеала. Пройдя по теплотрассе, к элеваторному узлу и стоякам, к тому времени, как вода оказывается в батарее, она обогащается различными взвесями, которые и оседают в радиаторах.

Из-за этого каждые несколько лет приборы необходимо промывать. Для этого процесса требуется доступ к промывочному крану, расположенному в нижнем углу радиатора с противоположной стороны от подводки. Таким образом, если отсутствует свободный доступ к прибору, нужно: либо удалять защитный экран (а это не всегда возможно), либо мириться с плохой эффективностью отопления. По этой причине, выбирая, чем закрыть батарею в комнате, следует отдать предпочтение такому изделию, которое позволит беспрепятственно получать доступ к отопительному прибору. Читайте также: «Как закрыть батарею отопления в комнате – выбираем оптимальный вариант».

Также нельзя забывать о том, что рано или поздно радиатор выйдет из строя. А поскольку отопительные приборы обычно скрывают из-за того, что они слишком старые и выглядят непривлекательно, то момента, когда потребуется ремонт, ждать остается недолго.

Основные виды неисправностей:

Как скрыть радиатор отопления декоративным экраном

Выбирая, как перекрыть батарею отопления, нужно учитывать несколько моментов:

1. Прежде всего, декоративный экран должен в минимальной степени препятствовать тепловому излучению и конвекции. Лучший вариант – пластиковое или металлическое изделие с крупноячеистой сеткой. В верхней части, откуда идет горячий воздух, не должно быть сплошной поверхности (прочитайте: «Декоративные панели для радиаторов отопления — выбираем короб и накладки»).
2. Также декоративный экран должен легко сниматься при необходимости. Еще лучше выбирать приставную модель, которая не имеет постоянных креплений. Также нужно обеспечить доступ к трубам.
   
   Если соблюдать эти две рекомендации, удастся скрыть батарею отопления, не препятствуя эффективному обогреву и доступу к отопительному прибору (прочитайте также: «Декорирование труб отопления — оригинальные идеи для декора»).
3. Не рекомендуется закрывать радиаторы гипсокартоном – в таком случае помещение будет плохо прогреваться, а при малейшей неисправности конструкцию придется разрушать. В любом случае, при обшивке батареи гипсокартоном, нужно сделать возле подводки к ней легкую пластиковую дверцу. Читайте также: «Как закрыть батарею гипсокартоном – пошаговое руководство по монтажу короба».

Виды декоративных экранов

На рынке можно встретить большой ассортимент изделий для украшения радиаторов, однако не каждое из них является практичным. Конечно, внешний вид экрана важен, но не стоит забывать о том, что батарея должна хорошо прогревать комнату.

Самым лучшим вариантом является изделие с крупной сеткой и открытой верхней частью (в крайнем случае, вверху должна быть не сплошная поверхность, а ячеистая). Также он должен легко сниматься. Очень красиво выглядят деревянные и пластиковые варианты. Можно установить такой экран на батарею своими руками, не прибегая к услугам специалистов.

От сплошного экрана с мелкими отверстиями рекомендуется отказаться – если закрыть радиатор отопления таким изделием, воздух в помещении будет плохо прогреваться. 

Когда позволяет семейный бюджет, лучше не скрывать старые батареи, а установить новые. Например, алюминиевые радиаторы выглядят современно и красиво. В продаже присутствуют модели разного дизайна, поэтому можно подобрать тот вариант, который лучше всего впишется в интерьер. В том, как закрепить радиатор отопления, нет ничего сложного – алюминиевые батареи имеют небольшой вес. В то же время они хорошо передают тепло воздуху в помещении, долговечны и устойчивы к коррозии. Читайте также: «Как украсить батареи отопления своими руками».

Если нет возможности поменять старые батареи на новые, можно скрыть их специальными декоративными экранами, однако нужно выбирать такие изделия, которые не будут препятствовать эффективному теплообмену и проведению ремонта.

90000 How do thermal batteries work? 90001 90002 What is a thermal battery? 90003 90004 Thermal mass of any kind can by definition be called a thermal battery, as it has the ability to store heat. In the context of a house, that means dense materials like bricks, masonry and concrete. Even a jug of water sitting in a sunny window is a thermal battery of sorts as it captures and later releases heat from the sun. 90005 90004 A well-insulated concrete floor acts as a thermal battery as well; once you pump it full of heat it takes a long time to cool down (depending on the thickness), and it regulates interior temperatures during that time.90005 90004 One practical use for getting the most from a radiant concrete floor as a thermal battery would be in areas with fluctuating energy costs — you can set your floor on a timer so it only comes on during low-rate hours (7pm to 7am in Ontario for example). During the twelve hours that it is off, it acts as a battery by slowly releasing the stored heat, so you avoid having to pay the higher rates during peak-hours. 90005 90010 MIT Solar House via Wikimedia 90004 As you move into the area of ​​active heat-storage systems, one of the more common types of thermal battery (not that there are a lot of them) is a huge water tank buried in the ground that is heated by solar thermal panels.90005 90004 Even this type of system is not new, the first house in the United States with an active solar heating system was built In тисяча дев’ятсот тридцять дев’ять on the MIT campus (Massachusetts Institute of Technology), and sat on top of a huge water reservoir that was heated by thermal solar panels. 90005 90015 MIT Solar House thermal battery via Wikimedia 90002 What are phase change thermal batteries? 90003 90004 Taking advantage of a ‘phase change’ raises the bar a bit — stick with me, it will be fun, I promise 🙂 90005 90004 A significant input of energy is required to cause a material to change from a solid to liquid.That energy is later released when that material solidifies again. While those transformations are happening and the material is either absorbing or releasing energy, the temperature will stay constant. Once the phase change is complete, the material will begin to change temperature again. 90005 90004 So what does that mean in real terms? It means that in order to melt water, wax, metal, rock or whatever, you need to feed it a ton of energy. but the temperature does not change while you are doing that.So your ‘battery’ has more power, and you can store more heat in the same volume of space. 90005 90004 It’s difficult to take advantage of a melting point of 0 ° Celsius, but wax melts at about 37 ° Celsius (depending on its exact chemical makeup), which is perfect for collecting and storing heat from solar thermal collectors. 90005 90026 90004 90005 90002 How to build a thermal battery: 90003 90004 If you had a heat-collecting solar panel (directly heating air or liquid rather than generating power with photovoltaics), you can use that to charge your thermal battery.Envision this — a large tank of wax (or water) that is warmed by heated coils from a solar collector. Through that same tank runs another coil that is extracting the heat to pump it through your radiant floor or whatever other heating distribution system you have. 90005 90002 Specific Heat Capacity: 90003 90004 If you take solid paraffin (heat capacity Cp = 2.5 kJ / kg · K and heat of fusion of 210 kJ / kg), let’s say 1 kg, at room temperature, you will need 2.5 kJ (kilojoules) of heat to make the 1 kg block go from 20 ° C to 21 ° C.To make it go from 21 ° C to 22 ° C, you will also need 2.5 kJ (i.e. the same amount of energy). 90005 90004 Paraffin melts at approximately 37 ° C. If it drops to 36 ° C, you will again only need 2.5 kJ to bring it back to 37 ° C, but you would need 210 kJ (84 times as much) to go from 37 to 38 ° C. 90005 90004 This is because in order to melt, some chemical bonds in the solid lattice need to be broken, a process that requires extra energy. So overall, if a kg of paraffin is lying around at 20 ° C, you would need 252.5 kJ to bring it to 38 ° C. 90005 90004 One of the more common building materials with thermal mass benefits is concrete. In contrast to paraffin, 1 kg of concrete (Cp = 0.88 kJ / kg · K) would need 15.8 kJ to do the same. For water (Cp = 4.18 kJ / kg · K), the amount of energy required would be 75.2 kJ. 90005 90004 The amount of energy put in is the amount of energy stored in a material, as this energy will later be released as the material cools back down to 20 ° C, or room temperature. While there are many materials that can be used in the application of heat storage, this is just a quick comparison of some of the more commonly available ones.90005 90004 So to conclude, paraffin can store 16 times as much heat per kg as concrete, and 3.4 times as much as water. So while water may not be the best material to store heat, it certainly is the most affordably priced and easily accessible. 90005 90004 90048 The Cp value referred to in the above text refers to the heat capacity of materials. 90049 90005 90004 q = m Cp ΔT 90005 90004 where: 90005 90004 q = energy [J] 90005 90004 m = mass of material [kg] 90005 90004 Cp = heat capacity of the material [kJ / (kg · K)] 90005 90004 ΔT = temperature difference [K or ° C] 90005 90004 90005 90065 See more about Passive Solar Home Design here 90066 90067 90068 90069 90070 90071 90072 90069 90070 90004 Thermal battery diagram courtesy of alternative-photonics.com / 90005 90071 90072 90079 90080 90004 90005 90004 Thermal battery diagrams are courtesy of Alternative Photonics. 90005 .90000 Why Your Phone Gets Hot | iPhone & Android Overheating 90001 90002 If your phone is getting hot or overheating, there are a number of possible causes. Whether you’re using an iPhone or an Android device, find out what’s making your phone get so hot, how to fix the problem, and how to stop it from happening again. 90003 90004 Why does my phone get hot? 90005 90002 A common question with no single answer, we’re here to help you super sleuth your way to the bottom of this 90007 hot 90008 topic (could not help ourselves).Note that this does not include your phone getting warm from time to time. Some warmth is completely normal. Your phone is an electronic device after all, so the movement of electricity required to make it work creates heat — that’s simple physics. But if your phone is regularly overheating to the point where it’s uncomfortable to hold, there could be a more serious problem going on that could ultimately make your phone age faster or cause other issues. 90003 90010 Why is my Android overheating? 90011 90002 Some of the common causes of phone overheating — such as malware and rogue apps — are more common on Android devices.If your Android device or battery regularly gets too hot, read on to learn how to turn down the heat. 90003 90010 Why is my iPhone overheating? 90011 90002 Because iPhones do not get viruses and Apple does not allow the installation of non-approved apps, you might think iOS devices are less prone to typical phone issues, including phone overheating. But, if you’re here, you’re probably wondering «why is my iPhone overheating so quickly ?!» Do not worry, we have answers. 90003 90002 90019 No matter if you have an Android or iPhone, the first step is figuring out the source of the overheating.90020 90003 90004 Where is the heat coming from? 90005 90002 When phone temperature rises, the most probable culprits are either the battery, processor, or screen. Each of these components can generate heat; chemicals inside your phone’s battery create electricity, the processor transfers information at high speeds (like a computer), and your phone’s screen emits light. So how can you pinpoint what’s causing the problem? You can make an educated guess about why your iPhone or Android phone is heating up based on where the heat is coming from.90003 90010 Back of the phone 90011 90002 If the back of your phone is getting hot, the problem may be an overheating battery. Most modern mobile phones use Li-Ion (lithium-ion) batteries that, despite their size, pack a powerful punch. Li-Ion batteries are generally safe, but malfunctions do sometimes occur. A hot battery could also be in need of replacement. 90003 90010 Bottom of the phone 90011 90002 See if the bottom of the phone gets hot when charging — if so, the problem might be with the charger.For both iPhone and Android, the most reliable charger will be the one from your phone’s manufacturer. But contrary to popular belief, third-party chargers are also fine as long as they’re from a reputable source. 90003 90010 Above the battery, by the speaker, or the screen 90011 90002 If you notice your phone is getting hot somewhere besides the battery or the bottom where it connects to the charger, other possible causes could be related to the phone itself or to external factors. 90003 90004 Hot vs.warm: What’s the difference? 90005 90002 Okay, so your phone is hot — or is it just warm? Generally, a phone’s internal temperature can reach 37 to 43 degrees Celsius (98.6 to 109.4 degrees Fahrenheit) and still be considered normal. Before you start jamming a thermometer into your phone’s charging port, there are some more practical ways to determine phone temperature: 90003 90002 90003 90002 If you’re using an Android phone, you can install the nifty AIDA64 app, which will give you a ton of information about your device’s hardware and software, including a phone temperature report.While Apple has expanded the information you can see in the «Battery Health» menu in its latest iOS 12.3 update, this does not include a temperature reading. 90003 90002 However, since we’ve already established that some phone heat is normal, it’s better to determine overheating based on how often you notice your phone getting hot, or if the temperature is physically uncomfortable. Your phone should not be getting hot several times a day, or for seemingly no reason. 90003 90010 iPhone vs. Samsung phone overheating 90011 90002 Some iOS users notice increasing phone temperature issues as their devices age.But there’s still a big difference between older models overheating more often (as they struggle to keep up with updates) and the really intense overheating seen with the Samsung Galaxy Note 7 battery explosions. The Transportation Security Administration (TSA) still does not allow that particular Samsung Galaxy model on flights. 90003 90002 Though the Galaxy Note 7 is a particularly extreme case, we recommend reading reviews before you buy a new device to make sure there are no inherent issues that will cause dangerous phone overheating (or any other problems).90003 90004 Causes of phone overheating 90005 90002 There are many normal (and harmless) reasons why your phone may need to use more power than usual, causing it to warm up a bit. These include: 90003 90010 1. Gaming for long periods of time 90011 90002 If you have not found yourself hours deep into a 90007 Candy Crush 90008 or 90007 Snake vs. Block 90008 marathon, then you’re either lying or you’ve somehow never had to take public transit. The sheer breadth of available mobile games is arguably one of the best reasons for buying a smartphone.However, high-intensity gaming apps use your phone’s central processing cores in addition to the graphics processing unit, which can make your phone warm up. 90003 90010 2. Streaming content 90011 90002 Similar to the gaming scenario, watching YouTube or Netflix for hours via your Android or iPhone is another surefire (get it?) Way to overwork your phone’s processor. Streaming content means your phone has to load the video data and keep the display active for a prolonged period of time. 90003 90010 3.Your settings are not optimal 90011 90002 Your phone’s settings also impact how much energy it uses. Screen brightness on full blast? Animated wallpaper? Widgets, widgets everywhere? Consider turning off (or down, in the case of screen brightness) unnecessary settings to lighten the load on your phone’s CPU. 90003 90002 Other reasons may not be related to your phone’s normal processes, but are still relatively easy to fix: 90003 90010 4. Environmental factors 90011 90002 Prepare to have your mind blown, but leaving your phone sitting outside in the sun or in your car on a hot day can cause it to overheat (* GASP *).This will also prevent the touch screen from working properly and cause the battery to drain faster. In addition to sun and heat exposure, water damage can also be a possible cause of phone overheating. 90003 90010 5. Apps that need updates 90011 90002 If an app has a bug or other problem, it may cause your phone to overheat by overusing your device’s processor. Keeping your apps and operating system updated is important because updates often include bug fixes. After you apply the update, your phone should have better performance and overheat less frequently.90003 90010 6. Software updates 90011 90002 A phone may overheat during or right after an update. This can be because there was a bug in the OS that required fixing through the update, which can require increased power in the moment (but should not trigger a long-term overheating issue). 90003 90004 When there’s a bigger problem 90005 90002 While there are many plausible explanations for why your phone is getting hot in here (so hot!), It’s better not to assume the problem is an easy fix.An chronically overheating phone can be a sign that your phone is infected with malware. Malware often consumes a ton of your phone’s RAM and CPU power, which causes the phone to overheat. Some types of malware are even capable of physically damaging your phone. 90003 90002 Despite the myth you sometimes hear, phones can get malware. Android phones can even get ransomware, a particularly nasty type of malicious software that locks up your files or device and demands a ransom to return access to you.And that’s not the only type of malware floating around. 90003 90002 With the explosion of Bitcoin, cryptocurrency has moved to the forefront of hackers ‘interest. In 2017, a strain of Trojan malware called Loapi infected Android phones by disguising itself usually as a fake antivirus app in the Google Play store. Loapi malware was used by hackers to secretly mine Monero cryptocurrency. This maxed out the processor’s computing power and caused the device to overheat, causing the phone’s battery to noticeably bulge just two days after the initial infection.90003 90002 There have also been a growing number of fake Android apps that infect devices with CoinHive, another Monero-mining malware. Hidden inside HTML files in the assets folder of the apps, the mining script activates once the app is opened and continues running in the background. Since many of these malicious apps have been found in the Google Play Store, paying attention to phone overheating is a useful way to identify a mining malware infection. 90003 90002 If you do suspect your phone is getting too hot due to a malware infection, see how to remove a virus from Android or iPhone.90003 90002 If you’re an iPhone user who sticks to the Apple App Store for approved apps, that will help limit your exposure to rogue apps. On the other hand, a jailbroken iPhone is just as vulnerable to malware as an Android. We recommend safeguarding your iOS device with a security app such as AVG Mobile Security for iPhone and iPad, which will protect you from all kinds of threats, including unsafe Wi-Fi networks and identity theft. 90003 90002 Due to their increased vulnerability, Android users should use a trusted mobile antivirus like our free AVG AntiVirus for Android.This is the best way to prevent malware from harming your device, and also protects against unsafe apps, unwanted callers, and theft. 90003 90002 Install FREE AVG AntiVirus for Android 90003 90002 90003 90004 How to cool your phone down 90005 90002 For a quick fix, first try removing your phone’s case. While the case itself should not be causing your phone to overheat, it might be trapping heat. Removing it can help lower your phone’s temperature more quickly. Next, turn on airplane mode to quickly deactivate battery-draining features like wireless radio, Bluetooth, and Wi-Fi or cellular signal search.This is not the most practical option, but it can be a quick way to help cool your phone down if it’s overheating. 90003 90002 Also, NEVER put your phone in the fridge or freezer. While this may sound like the logical counter response to leaving your phone in a hot environment, exposing your phone to extreme temperatures or moisture can cause irreparable damage. A better option (though admittedly limited in effectiveness) is to blow on or fan it. Both iPhones and Androids are designed to function between 0 to 35 degrees Celsius (32 to 95 Fahrenheit), but exposure to temperatures outside of that range can have a negative impact on your phone’s performance or hardware.If your phone is overheating because of direct sunlight or heat, you can move it to a shadier place. 90003 90002 In addition to the tips mentioned above, here are some other things you can do to help your phone cool off: 90003 90116 90117 90019 Use less power 90020 — Low Power Mode on iPhone and Battery Saver Mode on Android reduce the amount of power your phone is using, and can also help preserve your phone’s battery life. 90120 90117 90019 Install junk-cleaning software 90020 — Another useful way to minimize drain on your phone’s battery and processor power is to clear out junk.Cleaner apps, like AVG Cleaner, make it easy to clean out unnecessary files, identify apps that are slowing down your phone’s performance, and remove useless pre-installed apps to help improve your phone’s performance and extend its battery life. 90120 90125 90002 Install FREE AVG Cleaner for Android 90003 90002 90003 90116 90117 90019 Dim your screen brightness 90020 — Keeping the screen at a reasonable brightness (not full blast) will take some strain off your phone’s battery (and your eyes).90120 90117 90019 Turn off Wi-Fi, GPS, and Bluetooth 90020 — Disabling battery-draining features such as these gives your phone a break, allowing it to cool down. 90120 90117 90019 Restart your phone 90020 — Occasionally restarting your phone can help prevent overheating due to minor software problems. 90120 90117 Remove malware: As mentioned above, malicious software can make your device run in overdrive and overheat. Scan and remove it to improve phone performance and bring down the temperature.90120 90117 90019 See a professional 90020: If you’ve scanned your phone and determined it’s malware-free, but none of our other tips work, you might need to replace the battery. It’s best to visit a reputable repair shop and see if they can help diagnose the issue and / or get you a new battery, if necessary. 90120 90125 90004 How to keep your phone from overheating 90005 90002 It’s often easier to prevent issues in the first place than to learn how to stop your phone from overheating. Developing some basic phone-care habits can really make a difference when it comes to prolonging your phone’s life and delaying a phone replacement.90003 90010 Charge your phone correctly 90011 90002 We already mentioned using a reputable charger, but where you charge your phone is also important. Put it on a hard surface that will not conduct heat, and not your couch or bed — both of which will retain the heat produced by charging. And while we’re on the subject, a quick myth bust: charging your phone overnight actually IS NOT bad for your battery. The truth is that smartphones have protection chips to make sure a battery stops charging at 100%.Although it will charge again once the battery drops to 99%, you will not harm the battery as long as you maintain proper charging placement. 90003 90010 Update your apps 90011 90002 If you notice your phone has started heating up for no apparent reason, try looking at some of the apps you’ve recently installed. It’s possible that one or more of them may have a bug that’s causing your phone to overheat. Updating apps usually fixes this kind of problem; if not, try uninstalling the app to determine if it’s the reason your phone is overheating.You should also keep your operating system up-to-date for optimal device performance and security. 90003 90010 Avoid direct sunlight 90011 90002 This seems like a «duh» piece of advice, but it can be quite easy to forget about your phone when you’re outside soaking up the sun. Cover your phone with a blanket or something similar to prevent it from overheating — you may need to work on your tan, but your phone definitely does not. 90003 90010 Use an antivirus 90011 90002 We really can not stress enough how important it is to use strong antivirus software on your Android phone.Overheating aside, getting malware on your phone is going to give you a huge headache at the very least. At the most, malware could leak your sensitive information, steal your banking details, hold your device or personal files hostage, spy on your physical location, drain your battery — the list goes on, but the bottom line is this: do not be dumb with your smartphone. Make sure to use an antivirus. 90003 90002 Get free protection against insecure Wi-Fi networks and identity theft and secure your private photos against thieves or snoops with AVG Mobile Security for iPhone and iPad.Android users, guard against malware and rogue apps with extra protection of your sensitive data and photos with our free AVG AntiVirus for Android. 90003 90002 Install FREE AVG AntiVirus for Android 90003 90002 90003.90000 How to Seal your Battery in Heat Shrink — VRUZEND DIY Battery Kit 90001 90002 One of the best ways to seal your battery is by using heat shrink. It can protect your battery from short circuits, seal your battery against the weather and add a professional look to your DIY battery. 90003 90004 Choosing heat shrink 90005 90002 There are many different types of heat shrink available. For our purposes, we’ll generally be looking for large diameter heat shrink. This will be large enough to fit our batteries.90003 90002 There are also different styles of heat shrink. Not only does it come in different colors, but different materials are available as well. Most large diameter heat shrink is a fairly thin PVC heat shrink. 90003 90002 PVC heat shrink is great for battery use, but it can sometimes become brittle over time and begin to crack at the edges or at sharp corners. One method around this is to use multiple layers. This strengthens the heat shrink and adds a second line of defense if one layer should begin to crack.It also allows you to use multiple pieces of heat shrink perpendicular to each other to cover all six sides of a battery instead of just four sides, thus completely sealing your battery. Adding a thin layer of foam around your battery can also help prevent cracking of the heat shrink over time. 90003 90002 Thicker rubber style heat shrink is also available. This heat shrink can usually stand up to more abuse, but is also more expensive in the large sizes needed for battery use. 90003 90004 What size heat shrink do I need? 90005 90002 This is a really common question in battery building.It’s actually quite simple to determine, especially for square shapes. 90003 90002 First, you have to understand the sizes of heat shrink. Unlike small heat shrink for wires that is measured by the diameter, large size heat shrink is usually measured by the flattened width instead of the diameter. This is because it comes flattened on a roll and this method of measurement is easier. The flattened with is also half of the circumference of the circle formed by the heat shrink when it is opened. 90003 90002 Now to calculate the size heat shrink we need, we first calculate the perimeter of our battery.With the 4 inch thick and 5 inch wide battery below, we simply add the height and width together to get 9 inches (which is also half the perimeter of our battery). Since most heat shrink has a shrink ratio of 2: 1, we need a piece of heat shrink with a half circumference size of at least 9 inches. But we also need to make sure that the heat shrink is less than twice the size of the battery, meaning it can not have a half circumference size of more than 18. That means we need a piece of heat shrink that is between 9- 18 inches.Ideally, we’ll choose a piece that is closer to 9 inches so that it squeezes tighter on the battery. 90003 90002 90023 90003 90002 If that sounds complicated, then here’s the simple version: add the height and width of your battery to get a number. Then multiply that number by 2. You need a size of heat shrink between those two numbers. 90003 90002 Most heat shrink is measured in metric sizes, so you if you calculated in inches, you’ll need to convert to millimeters. Just multiply your inches by 25.4 to get millimeters. So instead of 9 inch heat shrink, we need at least 228 millimeter heat shrink. 90003 90004 Installing your heat shrink 90005 90002 To actually install your heat shrink, make sure you have all of your connections finished and that you’ve tested your battery. It’s annoying to have to cut open the heat shrink if you forgot something. 90003 90002 Once you know your battery is ready, prepare it by adding a layer of foam or fiberglass panels around the outside of your battery.You can skip this step, but it will help to reduce the stress on the heat shrink wrap from all of the terminal cap posts. 90003 90002 Next, making sure your wires are out of the way, slide a piece of heat shrink over your battery. Make sure the piece is long enough to over hand each side of the battery by at least half an inch. 90003 90002 Now, start adding heat from either a strong hair dryer set on ‘high’ or a heat gun set on ‘low’. Do not use a heat gun set on ‘high’, it can melt the heat shrink.90003 90002 Start on the ends of the battery, heating the heat shrink until it wraps around the corners of the battery. This will help keep it snug. Then heat the middle of the heat shrink, turning the battery to heat all of the heat shrink evenly. 90003 90002 Once that piece is fully shrunk on the battery, you have the option of adding a second piece at a 90 degree angle to the first. This will allow you to cover the two ends that were left exposed. This is not completely necessary, but can help make your battery more waterproof, if that is an issue.It can also help keep foreign objects (wires, fingers, insects, etc) from entering your battery. 90003 90002 And that’s it! Installing heat shrink was simple, right ?! If you ever need to open your battery, slide the heat shrink open carefully, especially if using a metal blade. Try to cut away from the terminals to avoid short circuiting the terminals with the blade. Good luck on finishing your battery!

As folks stay fit by refraining from smoking, lowering sugar intake and exercising, so also can battery life be extended. There are no hard numbers as to how effective good care is, but the proof is in examples where packs were issued as personal goods as opposed to stock items.Personal care almost always wins 90005 90002 Table 1 summarizes how to prolong battery life through proper attention. Because of similarities within systems, the chemistries are limited to lead, nickel and lithium. 90009 90005 90011 90012 90013 90014 90015 90003 Battery care 90004 90005 90019 90014 90002 90003 Lead acid: 90004 Flooded, sealed, gel, AGM 90005 90019 90014 90002 90003 Nickel-based: 90004 90009 NiCd, NiMH 90005 90019 90014 90002 90003 Lithium-ion: 90004 Cobalt, manganese, NMC 90005 90019 90039 90013 90014 90002 90003 Best way 90009 to charge 90004 90005 90019 90014 90002 Apply saturated charge to prevent sulfation; can remain on charge with correct float voltage.90005 90019 90014 90002 Avoid getting battery too hot on charge.
