How to Install a Battery Terminal

A cars battery connects to the vehicle through the terminals, which are the sleeves that fit over the battery posts. Acid and rust degrade the terminals, which, if not monitored, will cause the terminals to fracture and break. The wiring to the terminals is typically covered with rubber, protecting it from exposure to acid and water. Replacing the terminal is similar to splicing a line and only requires a few tools to complete.

Instructions

1

Disconnect the terminals from the vehicles battery starting with the negative terminal. Use a ratchet to loosen the terminal then pull it free from the battery.

2

Cut the damaged wire and terminal off with bolt or wire cutters. Cut the wire just behind the existing rubber sleeve to remove any corroded parts of the wire.

3

Use a razor blade or utility knife to trim off 1 inch of rubber from the rubber sleeve. Slice the rubber along its length then slide the rubber around the circumference of the wire. Pull the rubber off to expose the clean wire.

4

Place the wire into the new terminal retaining bolts. You have a few options for replacement terminals. The easiest to use will have the retaining bolts that tighten down onto the wire with a ratchet. The other types require specialized crimping tools to grab the wire. Tighten the retaining bolts until the wire cannot be pulled from the new terminal.

5

Install the terminals back onto the battery, starting with the positive connection. Make sure the terminals are pushed all the way onto the battery posts. Tighten down the terminals until they are secure.
