Del City charged over battery isolators

Del City says its battery isolators allow users to charge two batteries simultaneously and keep the starting battery isolated during times when power is being used, but the engine isn’t running. Battery isolators are useful in a vehicle with two or more batteries that help ensure that accessories don’t drain the start battery.

The battery isolators are designed to work on negative ground alternators and are rated from 12 to 48 volts; they only can be used with batteries that have the same voltage level. The battery isolators feature a heat sink design that helps cool the multiple high-current diodes that manage the isolation process.
