What types of batteries can HANMATEK digital battery testers check?
Our testers support 12V lead-acid batteries (regular flooded, AGM flat plate, AGM spiral, GEL, and EFB start-stop batteries) commonly used in cars, motorcycles, trucks, boats, RVs, golf carts, and lawn mowers. Some models also test 6V batteries and 12V/24V charging & cranking system.
-
Do the testers really measure battery health in seconds without removing the battery?
Yes. Simply connect the clamps to the battery terminals (no need to disconnect or fully charge). The tester performs a real conductance test and displays SOH (State of Health), SOC (State of Charge), CCA value, internal resistance, and estimated lifespan in under 5 seconds.
-
Can I test the vehicle’s starting and charging system?
Absolutely. All professional models include: Cranking test (measures starter motor voltage drop and cranking time) Charging test (checks alternator output at idle and under load, detects ripple issues) Results clearly show “GOOD,” “WEAK,” or “REPLACE” recommendations.
-
Is the tester safe and easy to use even for beginners?
Yes. It features reverse polarity protection, spark-proof clamps, and over-voltage protection. The large backlit LCD screen with multilingual interface (including English) shows clear pass/fail results—no professional knowledge required.
