Lisle Battery Terminal & Wiper Arm Puller 54150 — Compact dual-purpose, knurled cone for controlled lift

The Lisle 54150 is a compact dual-purpose puller designed to remove corroded battery cable clamps and tapered spline wiper arms quickly and without damage.

Whether you're a professional mechanic or a DIYer working in a cramped engine bay, the Lisle 54150 gives you a targeted, mechanical way to separate stuck battery terminals and bolted-on windshield wiper arms. Built for precision, the tool's knurled cone and center screw apply controlled force beneath the clamp or onto the spline post, helping you avoid prying with screwdrivers or risking component damage.

How does the Lisle 54150 remove stuck battery terminals safely?

The tool slips its jaws under the battery cable clamp, then the knurled cone is tightened to seat the jaws securely beneath the clamp lip. Turning the center screw lifts the clamp straight off the terminal, reducing sideways leverage that can bend or break terminals. This direct upward force preserves the terminal and cable for reuse when possible.

• Knurled cone secures jaws under the clamp for stable contact
• Center screw provides straight, controlled lifting force
• Minimizes bending or cracking of terminals and posts
• Compact profile works in tight engine-bay spaces

Can it handle bolted-on wiper arms with tapered splines?

Yes — the puller includes a screw pad shaped to seat on top of a tapered spline post, allowing the center screw to press against the post and pull the arm free. The design transfers force axially so the arm disengages from the spline without levering against the windshield or paint. It works on many common wiper-arm designs that mount over tapered splines.

• Screw pad fits over the spline post for centered pressure
• Axial pull reduces stress on the wiper arm and surrounding hardware
• Suitable for bolted-on arms that slip over tapered splines
• Helps prevent chipping or scratching during removal

What makes this puller practical for workshop and roadside use?

The Lisle 54150 is compact, durable, and straightforward to operate without special adapters. Its simple mechanical parts—jaws, knurled cone, and center screw—are easy to position and adjust, so you can work quickly under varied conditions. The tool stores easily in a toolbox or vehicle service kit for on-the-spot repairs.

• Small footprint fits toolboxes and service kits
• Rugged construction for repeated garage or shop use
• No electrical power or multiple attachments required
• Fast setup lets you remove terminals or arms efficiently

How should I use and care for the Lisle 54150 to prolong its life?

Use the puller on clean contact points when possible, tighten the knurled cone and center screw steadily, and avoid sudden wrenching motions. After use, wipe away corrosion or residue and store the tool dry to prevent rust. Periodic light lubrication of threads helps maintain smooth operation.

• Tighten evenly and avoid excessive force to protect threads
• Clean off battery acid residue or road grime after each use
• Apply light oil to the center screw threads as needed
• Store in a dry toolbox or pouch to reduce corrosion

Who is this for: The Lisle 54150 Battery Terminal and Wiper Arm Puller is suited to mechanics, fleet technicians, and home automotive enthusiasts who need a reliable, low-profile tool for removing stubborn battery clamps and bolted-on wiper arms without damaging parts. If you routinely service batteries, replace wiper arms, or maintain vehicles in tight spaces, this dual-purpose puller is a practical addition to your toolkit.
