Abstract
A battery protection device for preventing vehicle batteries from being drained to the point that the battery cannot start the vehicle includes an electrical meter that measures at least one electrical characteristic of the battery and a microprocessor. The microprocessor compares this measurement to a minimum starter value corresponding to a battery charge level below which the battery will not be able to start the vehicle. If the minimum starter value is equal to or greater than the current measurement from electrical property measuring device, the battery protection device will open a switch, disconnecting the battery. An indicator then notifies the vehicle operator that the device has been actuated and upon his return to the vehicle, the operator will be able to reset the device and start the vehicle or turn off the electrical device that was left on.
