Abstract
A booster battery assembly is provided, where the booster battery is intended for use to provide additional energy to vehicle batteries, while connected in parallel with such vehicle batteries, so that a sufficient source of cranking current is available. Moreover, it is important for the terminal voltage of the vehicle battery as boosted by the booster battery assembly to be about 6.0 to 8.4 volts for an average automobile in order for ignition to be initiated and maintained during cranking. The booster battery assembly is portable, or it may be permanently installed in the vehicle, but isolated from the vehicle battery. In any event, the booster battery assembly of this invention comprises a battery of the same terminal voltage as the vehicle battery but of much smaller capacity. The booster battery may be charged from the vehicle battery during a time when the vehicle alternator is operating, or it may be recharged from an AC source. It is also contemplated that the booster battery may be a one-shot, reserve type standby battery. The booster battery assembly is not intended to replicate an automobile battery, merely provide some additional starting energy to permit engine cranking and to maintain spark ignition during cranking.
