This amazing, patented, made in USA device will automatically disconnect your battery from your vehicle's electrical system if it discharges to a predetermined level. This still gives you sufficient power to restart your vehicle at a later time. This cut-off level means no more dead batteries due to lights or radio left on accidentally, small battery loads that drain a battery over time, defective circuits that sap power even when the engine is off, extended vehicle storage, etc. Ingenious circuitry then automatically reconnects the system when you get in and turn the key - and with the battery's full power the engine spins over easily and starts, whether after 10 minutes, 10 weeks or more!
