6V/12V Battery Tester for Lead-Acid Types

The leagend tester evaluates flooded, AGM, EFB and GEL batteries from 6 V to 12 V and also performs 24 V cranking and charging checks. It covers cars, trucks, motorcycles and marine craft. A one‑key quick test speeds up repetitive checks in a busy workshop. The 2.4 in colour screen and status LEDs give clear feedback for operators at any skill level.

Suits mechanics needing history logs

Built‑in storage holds 1400 records and captures 120‑second voltage curves for later playback, making it useful for fleet documentation and fault tracing. Auto temperature compensation maintains accuracy from −10 °C to 60 °C. It is not for users who only need a simple pass‑fail check or who require wireless data export.

CCA range 20‑2000 A with 350 records per test type

The tester measures cold‑cranking amps across the full 20 A to 2000 A span, handling everything from motorcycle cells to heavy‑duty truck banks. Each of the four test categories stores up to 350 results, giving ample headroom for daily shop use. It does not support higher‑voltage industrial systems beyond 24 V.

Questions about this item

Do I need a specific lead-acid battery type for the 6V/12V CCA tester to work?

The tester works with Regular Flooded, AGM, EFB and GEL lead-acid batteries rated 6V or 12V, covering cars, trucks, motorcycles and marine vehicles.

Can the tester still run cranking and charging checks on my 24V truck system?

Yes, it supports 24V cranking and charging system tests for heavy-duty 24V vehicles alongside the standard 6V/12V battery tests.

How do I confirm the tester is capturing live voltage curves correctly after setup?

The 2.4" TFT colour screen shows real-time voltage waveforms and can save and playback up to 120 seconds of curve data for verification.
