The Sealey BT2002 Digital Battery and Alternator Tester is a professional diagnostic tool designed for testing automotive electrical systems. This digital tester provides comprehensive analysis of battery condition, starter motor performance and alternator output, making it an essential piece of kit for mechanics, auto-electricians and mobile diagnostic services. The tester can assess battery condition with as little as 1V of residual charge and supports multiple rating systems including SAE, DIN, EN and IEC standards. It tests 6V and 12V batteries across a wide range of cold cranking amp ratings, from 25-2100 CCA depending on the standard used. The charging system capability extends to 24V for alternator testing, making it suitable for both passenger vehicles and light commercial applications. Operation is straightforward thanks to the clear LCD screen that guides users through each test with on-screen prompts. The unit checks starter motor condition without complicated connections or interpretation, whilst the charging system can be analysed both at rest and under load to accurately determine alternator health. A built-in voltmeter provides additional functionality for general voltage testing and system diagnostics. The tester's design eliminates heat and sparks during operation, ensuring safe testing in workshop environments. Its rugged construction features a protective cover to withstand the demands of daily professional use, and the compact unit weighs just 0.62kg for portability.
