Some small service jobs become difficult when a part is stuck on a tapered post. Battery cable clamps can seize to a battery terminal, and bolted-on wiper arms can hold tightly to the wiper transmission spline. The Lisle 54150 Battery Term & Wiper Arm Puller is a compact puller for those two specific removal jobs.

What the Lisle 54150 is designed to remove

Lisle describes the 54150 as a dual-purpose puller for battery terminals and bolted-on windshield wiper arms. The tool uses jaws, a knurled cone, and a center screw so the user can lift the part straight off instead of prying from one side.

  • Battery cable clamps that are stuck on the battery post
  • Bolted-on wiper arms that fit over a tapered spline
  • Jobs where controlled upward pressure is preferable to prying

When it makes sense for a buyer

This is the kind of tool to consider before a battery replacement, battery cable service, wiper arm replacement, or cowl-area repair where the wiper arm needs to come off cleanly. It is especially useful when the part has corrosion, age, or weather exposure working against it.

It is not a universal answer for every wiper design. The wiper-arm use case is for bolted-on arms that fit over a tapered spline. If the vehicle uses a different arm design, confirm the service procedure before ordering or using a puller.

Safety checks before you start

  • Wear eye protection and gloves, especially around batteries and corrosion.
  • Keep sparks, flames, and metal jewelry away from the battery area.
  • Follow the vehicle service information for battery disconnect order and any electronic memory procedures.
  • Mark the parked position of a wiper arm before removal so it can be reinstalled in the same location.
  • Protect painted cowl trim and glass, and stop if the arm or terminal does not move with reasonable force.

How the tool works

For battery terminals, Lisle specifies tightening the knurled cone to force the jaws under the cable clamp, then turning the center screw to lift the clamp off the terminal. For a suitable bolted-on wiper arm, the puller screw pad is designed to sit on top of the spline post while the screw lifts the arm.

That straight lifting action is the main reason to use a puller. Side-loading a battery post or prying near a windshield can damage surrounding parts, so a controlled pull is the better approach when the tool fits the job.
