Battery disconnect switches can help preserve battery life and prevent theft or tampering. They work by cutting off the connection between your battery and the 12-volt fuses that power the vehicle. Battery disconnect switches prevent constant drain while your vehicle is in storage and can be relatively easy to install.

How to Install a Battery Disconnect Switch

Installing a battery cutoff switch helps slow battery drain and can prevent RV or car theft. They provide an easy way for you to cut off power to the battery either directly or through a remote switch and take very little time to install.

  1. The first step is to select a battery switch based on the handle load of your battery and any interior lights, appliances or other components. Installing the incorrect switch can cause dangerous electrical problems, so refer to your RV or car manual for guidance.
  2. Prior to installation, first disconnect the negative (black) cable, and then the positive (red) cable from the battery poles.
  3. Remove the battery clamp and carefully clean off any buildup or debris on the battery terminals.
  4. The next step is to carefully unscrew the negative cable terminal using a Philips screwdriver, then wire the battery cutoff switch to the negative battery terminal
  5. Next, you will need to reconnect the cable terminal and find a secure, inconspicuous area to mount the battery disconnect switch.
  6. Once you have an area selected, drill a few pilot holes then secure the battery disconnect switch into place with the supplied hardware.
  7. The final step is to reconnect your battery cables to the battery. Make sure the switch is in the “on” position before attempting to start your vehicle to avoid blowing a fuse.
