Battery Terminal and Wiper Arm Puller - Dual-Purpose Removal Tool

In this review the Lisle 54150 is evaluated as a simple, dual-purpose hand tool for mechanics and DIYers who need a reliable way to remove stuck battery terminals and bolted-on wiper arms. The bottom line is that this puller addresses two common removal tasks with a small, focused design: it slips jaws under cable clamps to lift terminals and its screw pad fits spline posts to pull wiper arms, making it a practical shop staple for quick, controlled removal work.

Key Features

• Dual-purpose puller: Combines battery terminal removal and bolted-on wiper arm extraction so one tool covers two frequent tasks.
• Knurled cone action: Tightening the knurled cone forces the jaws under the clamp for a secure grip that helps free corroded or stuck terminals.
• Center screw lift: The turn center screw lifts the clamp off the terminal in a controlled manner to avoid bending or damage.
• Spline post pad: The puller screw pad is shaped to sit on top of the tapered spline post for efficient pulling of wiper arms without slippage.
• Compact, lightweight build: Designed to be easy to handle and store so it is convenient for both garage use and mobile service calls.

Who It's For

This tool is aimed at home mechanics, professional technicians, and fleet maintenance crews who regularly remove battery clamps and bolted-on wiper arms. It is particularly useful when a quick, non-destructive removal is required on late-model vehicles where access is limited.

Those who need a broad set of automotive tools for many different fastener types or heavy-duty industrial pullers may want a larger specialty tool, but for targeted battery terminal and wiper arm jobs this puller is a focused, efficient choice.

Pros & Cons
