Description
Overview:
The Sealey BT91/7 Battery Drop Tester is a handheld, American‐style load tester for quick checks on 6V and 12V lead‐acid starter batteries used in cars, vans, motorcycles, ATVs, ride‐on mowers and small plant. Built with a robust metal load element and a durable, insulated handle, it applies a controlled load to reveal the battery's true condition under stress. Internal switchgear engages the load safely, helping to prevent sparking at the clamps. A clear analogue gauge shows voltage behaviour during the test so you can spot weak or short‐circuited cells. Colour‐coded, heavy‐duty crocodile clips provide a secure connection to standard battery posts. Compact and workshop‐ready, the BT91/7 is a dependable tool for routine diagnostics, pre‐delivery inspections, and fault finding on 6V and 12V systems.
