Frequently asked questions
How should I charge this battery?
Use a charger designed for single-cell Li-Polymer batteries, which charges to 4.2 V and stops at that voltage. Do not charge it with a generic 5 V or 12 V supply directly.
The connector polarity does not match my device. What should I do?
Press down on the small latch of each crimp contact with a toothpick, then swap the contacts. Make sure the two contacts never touch each other while doing this.
