The Sealey BT91/7PF is a polarity-free battery drop tester designed for quick and safe testing of 6V and 12V batteries. This American-style drop tester features polarity-protected cables that prevent damage from incorrect connections, making it a reliable diagnostic tool for workshops, garages and mobile mechanics. Built with internal switchgear, this battery tester applies load without sparking, enhancing safety during testing procedures. The unit applies load across battery cells and measures output on an integrated meter, providing accurate indication of battery voltage and identifying faulty or short-circuited cells. This makes it ideal for diagnosing battery condition before replacement, troubleshooting electrical issues in vehicles, and routine maintenance checks. The polarity-free design eliminates the risk of damaging the tester through reverse connections, offering peace of mind during busy workshop operations where quick testing is essential.
