Lithium polymer (LiPo) batteries are commonly used in a wide range of portable devices such as smartphones, tablets, drones, and RC vehicles. These batteries are known for their high energy density, compact size, and lightweight design, making them a popular choice for powering portable electronics. However, LiPo batteries can be volatile and require specific care and handling to ensure their longevity and safe use. Caring for your LiPo battery is essential to ensure that it performs optimally and lasts as long as possible. By following some simple guidelines, you can keep your LiPo battery in good condition and avoid potential safety hazards. In this article, we will explore the best practices for caring for your LiPo battery.
Store LiPo Battery Correctly
LiPo batteries should be stored in a cool and dry place, away from direct sunlight and heat sources. Additionally, it is recommended to store your LiPo battery at a partial charge, around 50% to 60%, to prevent over-discharging or overcharging.
Use the Correct Charger
It is essential to use the correct charger and charging settings when charging your LiPo battery. Using the wrong charger or charger settings can damage your battery and cause it to overheat or explode. Make sure to use a charger that is designed for LiPo batteries and set the correct charging voltage and current according to the manufacturer’s guidelines.
Charging Cylce Life
Many people think that the life of a Li-Po battery is the number of recharges, but it is actually wrong. Strictly speaking, it should be called the charging cycle. A complete charging cycle is to charge 100% of the electricity, and then put 100% of the electricity. The life of lithium batteries is about 300-500 complete charging cycles. The correct statement about the life of lithium batteries should be 300-500 full charges and discharges.
In other words, suppose a battery is fully charged at 100%: 50% is used and 30% is charged. This is not a complete cycle. A complete cycle is to charge and discharge two 100%. This is actually 40%. At this time, there is a 90% cycle. And so on……
Lithium batteries have no memory effect. It is best to charge the battery with a small current. Generally, it is charged with 0.5C-2C. The small current is less irritating and can better maintain the battery.
Don’t Overcharge When Charging
Polymer lithium-ion batteries, if the charging time is too long, the possibility of expansion will increase.The chemical properties of lithium are very lively and it is easy to burn. When the battery is charged and discharged, the inside of the battery continues to heat up, the gas generated during the activation process expands, the internal pressure of the battery increases, and the pressure reaches a certain level. If there are scars on the shell, it will break, causing leakage, fire, and even explosion.And polymer lithium-ion batteries will only expand.
The use of lithium batteries in an environment that is too hot or too cold also has an impact on the life of lithium batteries, so on hot days, don’t put your mobile phone in the car or expose it to the sun; in winter, if it is more than minus 20 degrees outside, don’t take your mobile phone outside for a long time (long-term exposure), or put it in a warm pocket and use headphones (don’t use Bluetooth headsets, that one is also with lithium batteries).
Li-Po batteries: the temperature range is 0~+45℃ when charging; the temperature range is -20~+60℃ when discharging; the long-term storage environment of the battery is: temperature -20~+35℃.Jiangsu Jinyi New Energy Technology Co., Ltd. can develop customized batteries according to various circumstances such as the use environment and method of the battery.
Precautions for Common Problems in Repairing LIPO Battery
The power lithium battery pack should also pay attention to the usual maintenance. Only after the maintenance work is completed can the rechargeable battery be used for a longer time.Pay attention to the operating temperature.Lithium batteries should not be exposed to high temperature areas for a long time. If the operating temperature has exceeded 60 degrees, the migration of rechargeable batteries must be carried out immediately.Excessive operating temperature will not only harm the internal structure of rechargeable batteries, but will also continue to cause some risks. If your lithium-ion battery pack is relatively large and medium-sized, you must also be aware of this layer of problems.If the operating temperature is not too high, its safety factor can be guaranteed.
Pay attention to maintaining the battery on time.Nowadays, the lithium-ion battery protection board has corresponding maintenance function modules, which can improve battery life.When using this kind of condition, we must pay attention to some minor problems. If we find that the battery is abnormal, we must carry out repairs.If there is no repair to ensure everyone’s safety, or carry out demolition immediately.Don’t do it at a loss, the damage is also great. We must carry out regular repairs and replace them as soon as possible if there is a problem.
Disassembly and assembly are prohibited.If you have purchased a suitable lithium battery pack, then do not disassemble it again, especially not to let the rechargeable battery be hit or close to fire.Doing so is basically very dangerous. Even if the implementation of such special activities does not pose a risk, it will lead to safety accidents of the degree of rechargeable battery use, so it is not recommended to disassemble it.If your lithium-ion battery must be lost, at the same time create a relative solution, and you can’t throw it inthe end, lithium-ion power is still a huge environmental pollution, and if it is inadvertently, it will turn into a dangerous accident, so we must be cautious.Abandoned batteries should be put into recycling sites, which can also maintain the natural environment well.
The battery pack is quickly discharged when it is used. The reasons for this kind of situation are: the battery is not fully charged; the voltage and capacity of a single string vary greatly; the battery pack is micro-shorted or the battery pack is self-discharging, causing the battery pack to be consumed as soon as it is fully charged.According to the above defects, the battery pack can be recharged twice or the defective batteries can be replaced to deal with.
The entire voltage of the battery pack is only half of the nominal voltage or negative voltage. Under normal circumstances, this kind of condition usually occurs when the battery pack is just assembled. The reason is that the battery pack is connected incorrectly. The positive and negative electrodes are connected incorrectly or the individual batteries are not fully connected. If the battery pack is fully charged, it is normal but low voltage immediately after standing or using it for a period of time, this kind of condition may be due to large battery self-discharge or a micro-short circuit in the battery pack.If the nominal voltage is low or negative, be sure to wire it correctly twice.
The battery pack stopped working inexplicably during use. It is very likely that the reason is that the battery has been discharged and the protection board or the controller’s minimum standard lower voltage is reached. The protection board or the controller stops working; or the continuous working current is too large (such as when the electric vehicle is starting at a heavy load or climbing a hill) exceeds the design protection current of the protection board or the continuous current of the controller causes the protection board or the controller to stop working, which will cause the battery pack to stop working inexplicably.
Nickel-metal hydride batteries must not be used during storage.Lack of power means that the battery will not be charged immediately after application.In the absence of power storage and rechargeable batteries, it is easier to be potassium thiocyanate, crystals attached to the electrode plate, blocking the ion channel, resulting in insufficient battery charging and reduced battery capacity.The longer the idle time, the more serious the battery damage.Therefore, if you are not using a process rechargeable battery, you should charge it once a month to keep the battery healthy.
In summary, properly caring for your LiPo battery is essential to ensure its safe and optimal use. By following the guidelines outlined above, you can extend the life of your LiPo battery, prevent safety hazards, and get the most out of your device. Remember to always store your battery correctly, use the correct charger and charging settings, monitor your battery during charging and use, and handle it with care. With these best practices in mind, you can enjoy the benefits of your LiPo battery-powered device with peace of mind.
