Sealey BT2003 Digital Battery and Alternator Tester with Printer

The Sealey BT2003 is a digital battery and alternator tester with integrated printer, designed for professional automotive diagnostics. This versatile diagnostic tool enables mechanics and auto electricians to quickly identify battery and charging system faults with printable results for customer records and warranty claims. Engineered for safe and accurate testing, this battery tester can diagnose battery condition with as little as 1V of residual charge, eliminating the risk of sparks or heat during testing. The device works with 6V and 12V batteries across multiple rating systems including DIN, EN, IEC, JIS and SAE, with test ranges from 25-2100 CCA depending on the standard. The straightforward 2-line LCD screen provides clear prompts throughout the testing process, requiring no complex interpretation. The alternator testing capability analyses the vehicle's charging system at rest and under load on both 12V and 24V systems, identifying potential alternator failures before they leave drivers stranded. The integrated voltmeter function extends the diagnostic capability for additional electrical system checks, measuring voltages from 1.5-30V. Test results are displayed on screen and automatically printed for professional documentation. Built for workshop use, the BT2003 features rugged construction to withstand daily professional use. The complete kit arrives in a protective storage case with two rolls of thermal printing paper and comprehensive operating instructions, ensuring you're ready to start testing immediately.
