12V Battery and Alternator Analyser

The Shutao tester gives instant visual diagnostics for any 12V vehicle, covering cars, SUVs, motorcycles, light trucks, hybrids, RVs and boats. It works with regular flooded, AGM and GEL batteries, so one tool handles the whole fleet. The six LED indicators reveal charge level, alternator performance and cranking health in a single plug-and-play check. No batteries or external power are needed to operate the unit.

Reverse Polarity Protection and Pure Copper Clips

A built-in reverse polarity function prevents burnout if the clips are accidentally swapped on the terminals. Pure copper wires of 0.06mm² cross-section and matching clips deliver high conductivity and sensitivity for reliable readings. The non-slip housing design allows secure handling even while wearing gloves. A 25cm cable provides ample reach to battery posts in tight engine bays.

Six LED Patterns Cover Every State

The display uses distinct LED combinations to show exact voltage bands: all off for a dead battery below 4.1V, ON twinkling for 4.1 to 11.1V, ON steady with LOW twinkling for 11.1 to 11.5V, LOW steady with MIDDLE twinkling for 11.6 to 12V, and a green light at 2000 RPM confirming a healthy charging circuit. This immediate feedback lets you decide whether to charge, replace or trust the battery without guesswork.

Questions about this item

What voltage standard does the tester support, and what is the maximum charging voltage it indicates?

It works only with 12 V systems and the highest LED range tops out at 12.4 V charging voltage.

What are the physical dimensions and cable length needed to reach the battery terminals?

The housing measures 12.4 x 5 x 1.8 cm and the attached cable is 25 cm long.

How do you run the alternator test and which step is commonly missed?

Rev the engine to 2000 RPM and watch for a steady green LED; the step often missed is holding that speed long enough for the light to stabilise.
