Overview

The ABB BCT840 is a 6.5-ton dieless crimp tool engineered for cast and tubular battery connectors in industrial applications. This battery-powered SMART tool uses the Milwaukee M18 platform with two 1.5 Ah batteries, charger, carry strap, and case. It automatically senses connector barrel diameter to apply precise compression force, eliminating air gaps and forming solid, low-resistance connections. The tool embosses each compression for verification and operates 30% faster than prior models. It supports range-taking capabilities for Color-Keyed connectors, converting standard- and long-barrel splices into reducing splices within specified conductor ranges (e.g., 1/0–750 kcmil copper, 1/0–600 kcmil aluminum). The closed-head design unlocks for accessibility and rotates 180 degrees for ergonomic use. Complies with UL 486 for single-compression crimps with T&B Color-Keyed connectors (aluminum lugs with copper conductors require two compressions). Ideal for automotive, telecommunications, and industrial battery systems where efficiency and reliability are critical.

How to Crimp Battery Cables with the BCT840 Crimper

This guide provides instructions for safely and effectively crimping battery cables ranging from 4 GA to 4/0 using the BCT840 adjustable crimper, including initial setup, operation, and optional calibration checks.

Estimated time: 15m

Tools needed:

BCT840 Adjustable Crimper, Wire strippers, Pin gauge (for optional gauging)

Supplies needed:

Battery Cables (4 GA to 4/0), Casting Connectors, Tubing Connectors

  1. Observe Safety Warnings

    WARNING: The handles of the BCT840 crimper are non-insulating. Do not crimp on energized wires to prevent electric shock.

  2. Strip the Battery Cable

    Carefully strip the insulation from the battery cable without cutting or nicking the wire strands. Ensure the stripped length is appropriate for your connector.

  3. Select the Correct Tool Side

    Identify the type of connector you are installing (casting or tubing). Select the corresponding side of the BCT840 tool for the connector type.

  4. Set the Cable Size

    Turn the adjusting wheel until the pointer slot aligns with the selected cable size line (e.g., 4 GA, 2/0, 4/0). Ensure the wheel is in a positive detented position.

  5. Insert Cable into Connector

    Insert the stripped end of the battery cable fully into the connector barrel until it bottoms out.

  6. Position Connector in the Tool

    Place the connector into the BCT840 tool, positioning it between the die nest and the indenter. Ensure the die is located between the color code marks on the connector.

  7. Crimp the Connector

    Firmly close the handles of the crimper to crimp the connector onto the cable. Note that some connectors may require more than one crimp; refer to the connector's specific instructions if applicable. WARNING: Keep fingers and other body parts clear of the die nest during operation.

  8. Check Handle Spread Adjustment (Optional)

    To check the tool's adjustment, lay the crimper on a flat surface. Open the handles and release them, allowing them to close under their own weight. Measure the handle spread distance at the inner surface of the handle tips. The distance should be 14 inches ± 1/2 inch for proper adjustment.

  9. Adjust Handle Spread (Optional)

    If the handle spread is not within 14 inches ± 1/2 inch, adjust it. Turn the adjustment screw clockwise to increase the handle spread or counterclockwise to decrease it until the correct measurement is achieved.

  10. Gauge the Crimping Area (Optional)

    To gauge the crimping area, first close the tool jaws until they bottom. Select the side of the tool to be gauged (Casting or Tubing). Move the indenter until the pointer slot aligns with the selected cable size (1/0 for cast connectors, 2/0 for tubular connectors), ensuring the adjusting wheel is detented. Gauge the crimping area with a suitable pin gauge; the gauge diameter must fall within 0.405 ± 0.010 inches.
