A car battery isolator kit can bring you many benefits for your car, RV, or even motorized boat.
First of all, it performs as a dual battery relay, allowing you to keep a fully-charged primary battery, and keep using all accessories and devices in your car. This way the backup battery does not discharge when starting the car, without the need to disconnect from the primary power system. One battery is always ready to use, while the secondary battery is being used.
Battery isolators use hybrid technology which is compatible with most cars and trucks. They allow the secondary battery to be properly charged by an alternator output. Advanced kits allow a safe charge from your vehicle’s electrical charging system.
A Battery isolator allows you to always be with a preserved battery, fully charged, and ready for use – even when you stop the engine.
