Noco 90 Amp. Battery Isolator

Many vehicles have multiple batteries: one dedicated for starting the engine and the other to power accessories. Without a battery isolator, a battery with a lower charge will draw power from a battery with a higher charge, until the batteries equalize. The problem is known as multiple battery drain and could leave you with dead batteries. A battery isolator will prevent current from flowing from one battery to the other and each battery will act as an independent power source. This will ensure that the battery you dedicated for starting never gets drained.
  • Isolate your starting battery from your accessory battery
  • Eliminate multiple battery drain

140 Amp. Battery Isolator-High Performance


Rated 4 out of 5 by 1 reviewer.
Rated 4 out of 5 by Product seems to work. What more can I say? The product seems to work as expected. I installed it and hooked up the wires and it is working. The price was excellent though. Much cheaper than comparable units. It has been installed for just over a month and so far no problems and the second battery bank is getting charged. September 23, 2016
