Description
Overview:
The Sealey Professional Battery Drop Tester 6/12V - Polarity Free (BT91/7PF) is a hand-held diagnostic tool for checking the condition of 6V and 12V lead‐acid starter batteries used in cars, vans, motorcycles, compact plant, and garden machinery. Built with a robust metal housing, heat‐dissipating load element, and insulated heavy‐gauge leads with crocodile clips, it applies a controlled load to reveal weak or failing batteries. Its polarity‐free design lets you connect either way round without damaging the tester, which makes day‐to‐day use safer and quicker in busy workshops. The analogue gauge gives immediate, easy‐to‐read results so you can assess voltage under load and pinpoint issues such as faulty or short‐circuited cells. An American‐style format keeps operation simple for reliable checks on‐site or at the bench.
Key Features:
- Polarity‐free and polarity‐protected connection reduces risk from accidental reverse hook‐up
- Internal switchgear applies load without sparking for safer operation around battery gases
- Tests both 6V and 12V batteries used across vehicles and equipment
- Analogue gauge provides clear, instant readings under load
- Helps identify shorted cells, low state‐of‐charge, and weak cranking performance
- Durable metal case and protective grille over the load element for long service life
- Heavy‐duty, insulated crocodile clips and flexible leads for secure contact on terminals
- Compact, portable design suits workshop benches and on‐site diagnostics
- No mains power required; powered by the battery under test for quick checks anywhere
- Straightforward operation suitable for both professionals and DIY users
Typical Applications:
Routine battery health checks on cars, vans, motorcycles, ATVs, ride‐on mowers, compact plant, generators, and classic vehicles with 6V systems. Useful for pre‐MOT or service inspections, diagnosing hard‐starting complaints, confirming charging and cranking performance, and assessing stored or seasonal batteries before use.
