It utilizes the simplest and most advanced technology to keep all your batteries charged using the engine’s electrical system but isolating the starting battery so you never get stranded. The great thing about these is that you don’t have to reroute any alternator wires and they are fully automatic. Everything you need to do the job yourself.

When the engine is started, the starting and auxiliary batteries are separated allowing only the starting battery to be charged. When the charge voltage reaches 13.4 volts the voltage sensitive relay engages allowing both the starting and auxiliary batteries to be charged. This is indicated by the light in the top LH corner being illuminated. When the engine is stopped and the battery voltage falls below 12.9 volts the relay disengages separating the start and auxiliary batteries, at this point the indicator light will be out and the auxiliary battery continues to power any accessories without risk of draining the starting battery. The smart isolator also has Dual Sensing which senses the charge of both batteries. If either battery is receiving a charge, e.g. a battery charger is connected to the auxiliary battery; the relay will engage and charge both batteries. The dual battery kit is easy to install and comes with all components and instructions required to complete the install. There is no need to cut into any factory wiring that may void manufacturer's warranty. Condition: New, Manufacturer Part Number: DBK, Brand: True
