Product Number: BT91/7
Variations
A weak or failing battery can be difficult to diagnose with a simple voltage check alone a battery may show acceptable resting voltage yet still fail under load. The Sealey BT91/7 American-style drop tester solves this by applying a load across the battery cells and measuring the output on its built-in metre, giving an accurate indication of battery voltage and identifying faulty or short-circuited cells. Suitable for both 6V and 12V batteries, the load is applied via internal switchgear, eliminating the risk of sparking during testing. A straightforward, reliable tool for any workshop carrying out battery diagnostics.
