How to Install the BAC438 Battery Connectors

This guide provides step-by-step instructions for installing BAC438 battery connectors safely and effectively.

Estimated time: 30m

Tools needed:

Screwdriver, Wire strippers, Crimping tool, Heat gun

Supplies needed:

Battery connectors, Heat shrink insulation tubing, KOPR-SHIELD compound, Torque wrench

  1. Disconnect battery cables

    Before starting the installation, disconnect the battery cables from the battery posts. Note the location of the positive and negative terminals for correct reinstallation.

  2. Prepare the cable

    Carefully strip the insulation from the battery cable without nicking the strands. Ensure the conductor strands are clean and free of dirt.

  3. Select and crimp the connector

    Choose the appropriate connector based on the gauge of the battery cable. Insert the stripped end of the cable into the connector, position it in the crimping tool, and compress it according to the specified colored lines.

  4. Apply heat shrink insulation

    If using heat shrink insulation, position it over the connector and apply heat according to the instructions until it shrinks tightly around the connector.

  5. Install the connectors

    Connect the positive lead to the positive battery terminal and the negative lead to the negative terminal. Use a torque wrench to apply a torque of 10 to 15 ft. lbs. for proper installation.
