Abstract

An improved vehicle battery providing a constant source of reserve electrical power. The primary source of electrical power is contained within a housing and is connectable to an electrical load. The reserve battery is also contained within the housing and is selectably connectable in parallel to the primary battery by a switch or relay. The reserve battery is of at least equal electrical power to that of the primary battery. Therefore, an adequate reserve is always maintained, even for adverse and extreme conditions that would be too much for smaller reserve batteries, but includes circuitry to disallow discharging of the reserve battery unless it is connected in parallel to the primary battery.

Claims

1. A method for providing constantly available reserve battery power comprising:

installing a primary battery means and a reserve battery means into a housing, the primary battery means no more than approximately equal electrical power to the reserve battery means;

connecting the primary battery means to the electrical system of an automobile in a normal mode of operation, the electrical system including but not limited to a starter motor means, a starter solenoid means, and an ignition switch means;

connecting the reserve battery means in parallel to the primary battery means when desired to increase the total electrical battery power;

charging the primary and reserve battery means together; and

prohibiting discharge of the reserve battery means during charging.

2. A battery means comprising:

a first battery including connection terminals;

a second battery of at least of approximately equal electrical power as the first battery; and

a switch means to connect the second battery to the first battery in parallel, the switch means including a relay means.

4. The means of claim 2 wherein the relay means is connectable to the ignition circuit for an automobile.

5. The means of claim 2 wherein the relay means is operated by a manual switch means.

6. The means of claim 2 wherein the relay means operates only when the ignition circuit is actuated and the ignition key is turned to the "ignition" position.

3. A battery means comprising:

a first battery including connection terminals;

a second battery of at least of approximately equal electrical power as the first battery; and

a switch means to connect the second battery to the first battery in parallel, the switch means being located remotely from the housing.

7. A battery means comprising:

a first battery including connection terminals;

as second battery of at least of approximately equal electrical power as the first battery;

a switch means to connect the second battery to the first battery in parallel; and

an auxiliary electrical connection associated with the second battery means for powering auxiliary devices, the electrical connection being adaptable for use with audio means, whereby the auxiliary connection reduces interference caused by automobile engine noise for the audio means.

8. A battery means comprising:

a first battery including connection terminals;

a second battery o at least of approximately equal electrical power as the first battery;

a switch means to connect the second battery to the first battery in parallel; and

an electrical connection means for connecting a remote switch means.

9. A battery means comprising:

a first battery including connection terminals;

a second battery of at least of approximately equal electrical power as the first battery;

a switch means to connect the second battery to the first battery in parallel; and

an automatic shut-off means for switching to the second battery means upon detection of a minimum voltage or current.
