Frequently Asked Questions
Can I mix Lithium batteries with other battery types?
Mixing different battery types or combining new batteries with old ones can cause voltage and capacity differences, potentially leading to over-discharge, swelling, bursting, or fire hazards.
What happens when batteries with different capacities are used together?
Using batteries with different capacities or mixing new and old batteries can cause leakage, zero voltage issues, overcharging, and over-discharging, which may damage the batteries.
What causes zero voltage or low voltage in battery packs?
Possible causes include short circuits, open circuits, incorrect connections, de-soldering, cold solder joints, or wrong connections between batteries.
Why might a rechargeable battery pack not charge?
This could be due to zero voltage batteries, internal connection errors, faulty electronic components, charger failure, or extreme temperature conditions affecting charging efficiency.
