After the newly installed battery and floated for a certain period of time, the float voltage will tend to be even, because the newly used battery separator has high sulfuric acid saturation, poor gas recombination efficiency, and the saturation will slightly decrease after operation, then charging voltage will also be even. The following is the relevant data shows the battery float charge operation: float voltage new battery up to 2.260 V / monomer ~ 2.315 V / monomer, minimum 2.200 V / monomer ~ 2.220 V / monomer, the new battery may be unevenness within operation  3 to 6 months
