New Battery Isolators from Del City

Milwaukee, WI (September, 2008) - Do you have a high powered stereo system or other high power accessories in your vehicle that require a second battery? Battery isolators are a necessity in a vehicle with two or more batteries to insure that your accessories don't drain your start battery. Our battery isolators allow you to charge two batteries simultaneously and keep your starting battery isolated during times when you are using power, but not running the engine. Del City's battery isolators work on negative ground alternators and are rated from 12 to 48 volts. They can only be used with batteries that have the same voltage level. The battery isolators feature a heat sink design which cools the multiple high current diodes that efficiently manage the isolation process.
