Kingbolen BM800 6V/12V/24V Car & Motorcycle Battery Tester

Keep every battery and charging system in your workshop honest with the Kingbolen BM800 Diagnostic Tool, a professional-grade 6V/12V/24V battery and charging system analyzer built for cars, motorcycles, vans, and light trucks. Whether you run a busy service bay, sell batteries over the counter, or just want a trustworthy tool in the garage, the BM800 gives you fast, accurate answers instead of guesswork.

• Wide voltage coverage: tests 6V and 12V batteries for cars and motorcycles, plus 24V systems for trucks, vans, and commercial vehicles, all from one handheld unit
• Cranking and CCA testing: checks cold cranking amps and overall battery health so you can confidently confirm whether a battery is good, weak, or due for replacement
• Charging system analysis: evaluates alternator output and ripple to catch undercharging, overcharging, and diode issues before they leave a customer stranded
• Motorcycle-ready: dedicated settings for small-capacity motorcycle and powersport batteries where standard car testers fall short
• Clear, easy-to-read results: straightforward pass/fail style readouts take the guesswork out of battery diagnosis
• Durable, portable design: built for daily use on the workshop floor or thrown in a toolbox for mobile mechanics

The BM800 is ideal for independent workshops and auto electricians who need a reliable second opinion before quoting a new battery or alternator, for battery and parts retailers who want to test stock and warranty claims on the spot, and for serious DIY owners who maintain their own cars, bikes, boats, or classic vehicles.

Compact, versatile, and built around the electrical demands of modern vehicles, the Kingbolen BM800 is a smart addition to any diagnostic kit.
