Charging & Use Notes
- Only use when the battery voltage and plug type match the device.
- Stop charging immediately when any cell reaches 4.2V (normal cell voltage is between 3.7V to 4.2V).
- Before use, check the battery surface condition and confirm 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 recycle several times first.
