Noco 140 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
  • Charge multiple batteries or banks of batteries
  • Full current either leg
