The BAT 135 Battery Tester from Bosch is designed to test 6V and 12V batteries from 40-2,000 CCA, including AGM, gel cell, flooded lead-acid, start/stop EFB, and commercial SLI batteries using a micro-load test for accurate results. It can also test 12V and 24V charging systems with a diode/ripple test. The integrated printer captures test results for customer records, displaying the state of health and the state-of-charge percentage. Test clamps are detachable for service or replacement.
