Charging & Safety Notes

1. Fitment depends on matching voltage and plug type.
2. Stop charging immediately when any cell reaches 4.2V (normal cell voltage is between 3.7V~4.2V).
3. Before use, check that the battery surface is intact and the voltage is normal.
4. If a new battery will not hold a full charge or loses charge quickly, use a balance charger and cycle it several times.
