Charge

· Battery charge should be used appropriate charger.

· Forbidden to use modified or damaged charger.

· Forbidden to charge over 24 hours for battery.

· Charge current: can't surpass the biggest charge current specified by battery specification.

· Charge voltage: can't surpass the highest charge voltage specified by battery specification.
