About The Product
Accurate Battery Testing
The BM310 battery tester offers an easy way to analyze battery status, view real-time charging progress, and detect system faults without leaving the vehicle. Ideal for routine maintenance and early fault identification .
Compatible with 12V Multiple Battery Types
This automotive battery tester works with all 12V charging systems and is compatible with regular flooded batteries, AGM flat plate, AGM spiral, and GEL batteries. Widely applicable for vehicles, forklifts, hybrid cars, pickups, boats, RVs, motorcycles, and travel trailers.
6 LED Indicators for Instant
Suitable for both home and commercial use, six LED lights clearly display battery and alternator status. When the green light is on, accelerate the engine to 2000 RPM — if the green light remains lit, the charging circuit is functioning properly. In battery check mode, the LEDs indicate the remaining battery charge percentage.
Durable Design with Safety Protection
Built-in reverse polarity protection prevents damage caused by incorrect connection between the positive battery post and negative cable terminal. Pure copper wires and clamps ensure excellent conductivity and high sensitivity. The non-slip handle design allows flexible operation even while wearing gloves.

Simply connect the positive and negative clamps to quickly read battery health status and charging system performance. No external power supply or complex setup is needed, making it suitable for daily garage maintenance, pre-trip inspections, and quick diagnostics in repair shops.
