Frequently Asked Questions
Can I mix lithium batteries with other battery types?
Mixing different battery types or new batteries with old ones can cause voltage and capacity differences, potentially leading to over-discharge, swelling, bursting, or fire hazards.
What happens if batteries with different capacities are packed together?
Using batteries with different capacities or mixing new and old batteries may cause leakage, zero voltage, overcharging, or over-discharging, which can damage the batteries.
What causes zero voltage or low voltage in battery packs?
Possible causes include short circuits, open circuits, wrong connections, de-soldering, cold solder joints, or incorrect battery connections.
Why can't my rechargeable battery or battery pack be charged?
This could be due to zero voltage batteries, internal connection errors, PCB component abnormalities, charger failure, or extreme temperature conditions affecting charging efficiency.
