An otherwise regular 12 volt 60 Ampere-hour automotive storage battery comprises a built-in automatic electronic inverter-type battery charger. This built-in battery charger is operable to connect with an ordinary 120 Volt/60 Hz power line by way of an electrical power cord having a male plug at one end and a female plug at the other end－with the male plug being adapted for insertion into an ordinary household electrical outlet and the female plug being adapted for insertion into a recessed male receptacle means mounted on the body of the battery. When so connected, the built-in battery charger is operable to charge the battery at a six Ampere rate until fully charged. At the point of full charge, charging automatically terminates and is restarted only if the magnitude of the voltage across the battery terminals falls below a predetermined level. There is complete electrical isolation between the terminals of the recessed male receptacle on the storage battery and the battery power output posts. The volume occupied by the built-in battery charger is only on the order of four cubic-inches, and can therefore be readily comprised within a sealed enclosure integral with the battery case.

In an automotive-type storage battery having a casing and a pair of battery terminals operative to permit connection with a load, the improvement comprising: inverter means including isolation means; and charging input terminals means: (i) fastened onto the casing, (ii) physically separated from the battery terminals, (iii) connected in circuit with the battery terminals by way of the inverter means including its isolation means providing for electrical isolation between the charging input terminals means and the battery terminals, and (iv) adapted to receive power from a power source for charging the battery; thereby permitting the battery to be charged from the power source without having to make direct electrical connection between the power source and the battery terminals; thereby, in turn, preventing a person from getting an electric shock from the power source by touching one of the battery terminals, even though the person may at the same time be in electrical connection with the power source. A storage battery having a casing and a pair of battery terminals operative to permit connection with a load, comprising: inverter means; and charging input terminal means being: (i) mounted in substantially rigid relationship with the casing; (ii) separate of and located away from the battery terminals; (iii) connected with the battery terminals by way of the inverter means; and (iv) operative to receive charging current for charging the storage battery.
