FAQ

Q: What is the lifespan of a polymer lithium-ion battery?

A: Typically, the lifespan of a polymer lithium-ion battery can reach 300-500 cycles of charge and discharge.

Q: Can a polymer lithium-ion battery be overcharged?

A: No, it cannot. Overcharging can cause the chemical reactions inside the battery to become irreversible, which can damage the battery's structure and even lead to dangerous situations such as battery explosions.

Q: Can a polymer lithium-ion battery be over-discharged?

A: No, it cannot. Over-discharging can cause the electrolyte in the battery to break down and the chemical reactions inside the battery to become out of control, which can damage the battery's structure and even lead to dangerous situations such as battery explosions.

Q: How should polymer lithium-ion batteries be stored?

A: Polymer lithium-ion batteries should be stored in a cool, dry, and well-ventilated place. If not in use for a long time, the battery should be fully charged before storage, and its battery level and status should be checked regularly.

Q: Can polymer lithium-ion batteries be used at any temperature?

A: The optimum operating temperature for polymer lithium-ion batteries is 20-25℃, but they can also be used at other temperatures. However, their performance may be affected to some extent.

Q: How should polymer lithium-ion batteries be charged correctly?

A: During charging, the original charger or a charger that meets the battery specifications should be used, and charging should be carried out in accordance with the charging requirements specified in the battery specifications and usage manual. Typically, the charging current for polymer lithium-ion batteries should be around 1C of the battery capacity.

Q: What safety precautions should be taken when using polymer lithium-ion batteries?

A: When using polymer lithium-ion batteries, care should be taken to avoid overcharging, over-discharging, short circuits, high temperatures, ignition sources, and to avoid using excessively worn batteries, storing the batteries for extended periods in high temperature or humid environments, and direct contact between the battery and other metal substances. At the same time, when using and storing polymer lithium-ion batteries, care should be taken to operate in accordance with the battery specifications and usage manual.
