Our battery kept draining off and we have yet to trace where is the leakage. We decided to get this Battery Terminal Isolator. Installation is rather simple and it does not cost much. Basically remove the negative terminal and install the Battery Terminal Isolator. Once this is install all the 12V electrical supply is cut off including the remote door control. But cutting off the supply simply turn the green knob.
Ideally this is for any machinery that is less frequent use, our BOV is one of them. This will also prevent any vehicle thief as the vehicle cannot be started with engaging the green knob. If you need to purchase this item us know as this item is made in Taiwan.
