The battery charging voltage for a lead-acid battery varies with the type, charging method and purpose of the battery. Usually, the charging voltage ranges from 2.25 to 2.45 volts. Upon charging, a lead-acid battery passes through three stages; bulk, absorption and float. This also leads to a variation of voltage in these stages.
It denotes a charging curve where the maximum allowed charging current is applied to the battery as long as the cell voltage is below its maximum value, for example, 4.2 Volts.
