Reliably check your battery’s condition anytime, anywhere. The Qoltec digital tester offers fast and precise diagnostics for 6 V, 12 V and 24 V batteries in the range of 30–200 Ah. With a large 2.8" LCD, intuitive operation, and power drawn directly from the tested battery, it provides accurate SOC/SOH measurements, checks CCA, the alternator, internal resistance, and lets you save snapshots of results.

The Qoltec battery tester is a practical tool for quickly verifying the condition of starting and stationary batteries. It supports a wide range of technologies: AGM, GEL, SLA, EFB, WET and DRY (lead-acid). Thanks to SOC (State of Charge) and SOH (State of Health) measurements, you can easily determine the current charge level and overall battery health, and detect performance drop in time.

The device is simple to use, features a clear 2.8" LCD, and is powered directly from the tested battery—no additional cells are needed. The tester measures voltage, CCA cranking current, internal resistance, alternator test, and lifecycle test. With compact dimensions and reverse-polarity protection, it fits any vehicle or workshop, and includes an elegant carrying case.

Main advantages:
- Accurate diagnostics of 6 V / 12 V / 24 V batteries (30–200 Ah)
