Lipo batteries are one of the commonly used batteries, widely used in various digital electronic products. However, did you know that their lifespan is also limited? The specific replacement time depends on the product they are used in, so we can only provide a reference for you.
When do you need to change your lipo battery?
First of all, the life of lipo batteries is usually measured by the number of cycles. The number of cycles refers to the complete charging and discharging cycle from full charge to complete discharge. Generally, the design life of polymer lithium batteries is 300-500 complete charging and discharging cycles, but the actual life may be affected by usage conditions and charging and discharging methods.
Secondly, as the charging and discharging cycles progress, the capacity of polymer lithium batteries will gradually decrease. Generally, it is recommended to consider replacement when the battery capacity decays to around 80% of the original capacity. However, this is only a general indicator, and specific judgment should be made based on usage requirements and performance requirements.
The last but not the least, lipo batteries are safer compared to other types of lithium batteries, but still need to be used with caution. If the battery shows obvious abnormalities such as swelling, leakage, or temperature rise, or if there is frequent rapid consumption of power during normal use, it may indicate a problem with the battery and it needs to be replaced in a timely manner.
What you need to mind when changing lipo battery？
As an important type of battery, polymer lithium batteries need to follow some precautions during use to ensure their long-term normal operation. Here are some precautions for replacing and using polymer lithium batteries:
When replacing polymer lithium batteries, be sure to choose original and regular batteries from the manufacturer to avoid buying second-hand or turnover batteries. When purchasing batteries, pay attention to the production date, registered trademark, and specifications to ensure that the handwriting is clear and the appearance is neat.
After replacing the polymer lithium battery, be careful not to overcharge or over discharge it. It should be used as needed and not fully depleted to avoid shortening the battery life.
In addition, the life of polymer lithium batteries will also be shortened when charged or discharged under high or low temperature environments, so it is necessary to avoid using them for a long time in extreme environments.
The charger is also a point to pay attention to during use. Improper charging operations can cause premature swelling of the polymer lithium battery and shorten its life. When using, pay attention to using the correct charging equipment and do not use a high-power charger to charge a low-power battery to avoid overcharging.
When replacing the polymer lithium battery, you can ask the repairman to check whether the output voltage of the original charger is stable. If it exceeds the standard, it should be replaced with a new charger. At the same time, do not use chargers with too high or too low voltage to charge, so as not to cause damage to the battery or pose a risk.
Finally, if the polymer lithium battery appears severely swollen, can only be used for five minutes after two hours of charging, or the cycle count increases frequently, the battery needs to be replaced to ensure normal use.
In addition, there are several aspects worth noting, such as chargers. Some improper charging operations can cause premature swelling of the polymer lithium battery and shorten its life.
① During the use of polymer lithium batteries, remember not to use the wrong charging equipment for the products you are using. For example, using a high-power charger to charge a low-power battery several times will cause the battery to swell and reduce its effectiveness.
② When replacing a polymer lithium battery, you can ask the repairman to check whether the output voltage of the original charger is stable. If it exceeds the standard, it is recommended to replace it with a new charger.
Polymer lithium batteries are a type of lithium battery with high energy density, light weight, and relatively high safety. They are widely used in mobile devices, smart watches, wearable devices, and other fields. The life and replacement of polymer lithium batteries need to be determined based on multiple factors, including usage conditions, charge and discharge cycle counts, and degree of capacity decay.
In short, the timing for replacing polymer lithium batteries is mainly determined by factors such as the number of battery cycles, capacity decay, and safety. If there is significant battery decay, capacity reduction, or safety issues, it is recommended to replace them in a timely manner to ensure the normal operation of the equipment and the safety of the user.
