Installing a side mount battery into a vehicle designed for top post batteries can be done with a simple and economical conversion. Pairs of threaded side post terminal adapters are sold at your local auto parts store or the automotive section of some hardware and department stores.

Step 1

Ensure that the ignition and anything electrical is turned off.

Step 2

Wear safety goggles/shield and gloves . Follow any manufacturer labels and precautions on batteries and in your owner's manual.

Step 3

Disconnect the black negative (-) ground cable. Always disconnect the negative first.

Step 4

Disconnect the red positive (+) power cable. Make sure the cables are tucked out of the way during the next step.

Step 5

Install the terminal adapters and tighten them in position. They will look like the top posts with threads on the ends. One will be marked negative (-), the other positive (+). Make sure they are matched to the proper side terminals.

Step 6

Reconnect the red positive (+) power cable. Always reconnect red (+) first.

Step 7

Reconnect the black negative (-) ground. Always reconnect black (-) last.

Step 8

Double check for tightness, proper polarity and any tools lying around before starting the vehicle.
