Charging & Safety Notes
- Compatibility depends on both voltage and plug type.
- Stop charging immediately when any cell reaches 4.2V (normal cell voltage is between 3.7V and 4.2V).
- Before use, check that the battery surface is intact and that the voltage is normal.
- If a new battery will not hold a full charge or loses charge quickly, use a balance charger to charge and cycle it several times.
