ABSTRACT:
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.
