Abstract:
1. A finish charge device for a battery having a positive and a negative terminal, including, in combination: electronic circuitry; a plurality of leads in electrical connection to said electronic circuitry, including an input lead for electrical connection to a standard charger or alternator, an output lead for electrical connection to a terminal of a to-be-charged battery, and a voltage sensor lead for electrical connection to the terminal of such a to-be-charged battery; said electronic circuitry including an input voltage sensor in electrical connection to said input lead, a finish charge power supply in electrical connection between a standard battery charger or alternator through said input lead and a to-be-charged battery through said output lead, electronic switches in electrical connection between a standard battery charger or alternator through said input lead and a to-be-charged battery through said finish charge power supply and said output lead and said voltage sensor lead, and wherein all said electronic circuitry components are discrete; and a microprocessor in electrical connection with said electronic circuitry and all of its components; whereby said microprocessor of said finish charge device is programmed to use input power from a standard charger or alternator or to-be-charged to provide an advantageously higher voltage finish charge to a to-be-charged battery, and wherein said electronic switch functions to selectively transfer input power to said finish charge power supply and then output power at the said advantageously higher voltage to a to-be-charged battery, said electronic switch functions to leave a to-be-charged battery disconnected from any form of charging, or to connect a to-be-charged battery to said finish charge power supply, or to connect a to-be-charged battery to a standard charger or alternator or external load, all as controlled by said microprocessor.
