How to Charge XS power D3400 Batteries

However, when the battery must be charged using dedicated battery charger, it is highly recommended to use smart/intelligent AGM battery charger with temperature compensation and use setting for the cycle battery charge, which is usually around 13.6 - 13.8 volts.

Float/standby voltage setting may also be used as long as the maximum end charging voltage is 14.4 volts (+/- 0.3 volts, depending on the temperature).

If higher voltage is applied over longer period of time, gassing may occur, damaging the battery.
