Sealey Digital Battery & Alternator Tester 12V BT01

Sealey

The Sealey BT01 is a compact digital battery and alternator tester designed for accurately diagnosing 12V vehicle electrical systems. This professional diagnostic tool tests battery condition, cranking performance and alternator output without generating heat or sparks, eliminating the risk of misdiagnosis common with traditional testing methods. The tester operates without an internal battery and can assess batteries with a residual charge as low as 7V, making it suitable for testing severely discharged units. Simply key in the battery rating from the information printed on the battery casing, and the results are displayed clearly on the LED control panel. The lightweight design at just 0.19kg makes it highly portable for mobile mechanics and workshop technicians. Supporting multiple international rating systems including DIN, EN, IEC, MCA and SAE standards, this tester covers a comprehensive range of battery capacities from 55 to 1200 CCA depending on the rating system used. The 7-15V voltage range provides flexibility when diagnosing various battery conditions and charging system faults. Ideal for automotive workshops, mobile mechanics and fleet maintenance teams requiring reliable battery and charging system diagnostics without complex equipment or guesswork.
