A lead battery assembly including a lead battery, a voltage-detecting circuit used to detect the voltage of the lead battery and an automatic voltage-charging circuit, these circuits being connected to the lead battery and contained together with the lead battery in a housing, a connecting base being electrically engaged with the above circuits wherein the connecting base is adapted to engage with a charger for a nickel-cadmium battery whereby when the detecting circuit detects that the voltage of the lead battery reaches a certain value, it will send a signal to the voltage-changing circuit to slowly lower the voltage thereof and after the total voltage of the lead battery and the voltage-changing circuit change from an increasing state to a decreasing state, the charger will sense the decreasing voltage and stop charging the lead battery so that the lead battery is permitted to be charged by a charger for a nickel-cadmium battery. Another embodiment uses two connecting bases, one for charging the lead battery and the other for attachment and supply of power to an electrical appliance. Another embodiment uses an adapter between the base and the charger which adapter houses the detecting circuit and the voltage-changing circuit.
