How to properly charge and maintain lithium polymer batteries on a daily basis

Lithium ion polymer batteries have been widely used in various portable electronic devices, such as smartphones, laptops, power tools, etc.

This type of battery is highly favored due to its lightweight, large capacity, and high energy density.However, in order to maintain the optimal 

performance of lithium-ion polymer batteries and extend their lifespan, the correct charging method is crucial.This article will comprehensively 

introduce the correct charging method for lithium-ion polymer batteries, and explain their charging principles, precautions, and daily 

maintenance skills.

Basic characteristics of lithium-ion polymer battery

Lithium-ion polymer battery, referred to as lithium polymer battery, is a solid electrolyte battery, which is improved on the basis of traditional 

lithium-ion batteries, using polymer electrolyte instead of liquid electrolyte. Compared with traditional lithium-ion batteries, lithium-polymer 

batteries have the advantages of small size, customizable shape, light weight and high safety. However, lithium polymer batteries are also 

resistant to overcharge and overdischarge, and must be charged under the supervision of a dedicated charger to avoid battery damage.

lithium polymer batteries, in the process of charging and discharging by lithium ion embedded between is negative and come out to store 

and release energy. During this process, maintaining regular charging cycles and avoiding extreme conditions are very important for battery 

life. Improper charging methods may lead to battery capacity reduction, voltage instability and even heat expansion, and even danger in serious 

cases.

Correct charging principles for lithium-ion polymer batteries

Correct charging Lithium-ion polymer batteries should first follow their charging principles:

1.Use the matching charger: Make sure that the charger used is suitable for your battery specifications. Different capacities and brands of 

batteries often require different charging currents and voltages.

2.Avoid overcharging: Try not to charge for a long time (such as overnight), and disconnect the power supply when the battery is full.

3.Suitable charging environment: Lithium polymer batteries should be charged in a suitable temperature (0 ° C ~ 45 ° C) environment, avoid 

high or low temperature charging, so as not to affect the battery life and performance.

4.Avoid using the device while charging: Using the device during charging may cause excessive battery heat and should be avoided as much 

as possible.

5.Do not wait until the battery is completely empty before charging: Lithium polymer batteries have no memory effect, so you do not need to 

wait until the full discharge before charging.

In addition to the above charging principles, users should also maintain certain use habits during daily use, such as avoiding placing devices 

containing batteries in direct sunlight or closed vehicles, because the high temperature environment may lead to reduced battery performance 

and even danger. Beating and squeezing the battery should also be avoided as much as possible to prevent damage to the internal structure 

of the battery.

Maintenance and Daily Care of Lithium ion Polymer Batteries

To maintain the best performance of lithium polymer batteries need for proper maintenance and daily maintenance:

1. Regularly perform capacity calibration: discharge the battery until the device indicates low battery level and shuts it off, then fully charge to 

calibrate the displayed capacity of the battery.

2. Reasonably arrange the charging cycle: complete the discharge and complete charging cycle process in a timely manner. It is recommended 

to do it every 1-2 months to help maintain the stable state of the battery.

3. Keep the battery dry: Water and batteries are natural enemies. Try to avoid contact between the battery and water to prevent short circuits 

or other damage.

4.Avoid using non-original spare parts and accessories: To ensure optimum performance and safety, use original or certified batteries and 

chargers.

5.Appropriate storage power: If the lithium polymer battery is not used for a long time, its power should be maintained at about 50%-60%, and 

placed in a dry and cool environment, and charged every 3-6 months to maintain power.

In summary, through reasonable charging, usage, and maintenance, the service life of lithium-ion polymer batteries can be significantly 

extended while maintaining their good performance.Users should follow the correct charging and maintenance methods according to specific 

battery and device guidelines to achieve optimal results.
