FAQs

Q: What should I do if the battery drains quickly even after a full charge?

A: Check whether the power consumption of the device is abnormal
Low temperatures may cause a temporary drop in capacity
Replace the battery if it suffers from cycle aging and increased internal resistance
Fictitious power is mostly caused by uncalibrated BMS

Q: What should be noted during transportation and storage?

A: Insulated packaging to prevent short circuits
Charge to 50% for long-term storage and recharge once every 3 months
Keep away from high temperatures, fire sources and water immersion

Q: How to calculate the cycle life?

A: Based on complete charge-discharge cycles from 0-100%, conventional lithium batteries achieve at least 800 cycles, while lithium iron phosphate batteries can reach over 3000 cycles; a remaining capacity of ≥80% after cycling is considered qualified.

Q: What is the scope of warranty?

A: A 5-year warranty is provided for non-human-induced quality issues; damage caused by human error, unauthorized disassembly, or improper use is not covered by the warranty. The service life is 10 to 15 years.

Q: Can I keep the charger plugged in all the time?

A: It is not recommended to keep fully charged and float charging for a long time, as this will accelerate aging; unplug the charger once fully charged, and maintaining a battery level between 20% and 80% in daily use will make it more durable.

Q: Can a swollen lithium battery still be used?

A: It is strictly forbidden to continue using it. Bulging indicates internal gas production and a risk of fire and explosion. Stop using it immediately and recycle it.

Q: What are the impacts of using it at high and low temperatures?

A: Recommended operating temperature: 0℃-45℃;
Low temperature: rapid capacity drop, easy lithium plating during charging
High temperature: accelerated aging, thermal runaway induced

Q: How to extend battery life?

A: Avoid overcharging, over-discharging and high-current fast charging
Prevent exposure to high temperatures and forced charging at low temperatures
Reduce full-charge storage and perform shallow charging and discharging regularly
