12V Battery and Alternator Analyser

This handheld analyser checks 12-volt lead-acid batteries and the vehicle charging system. It reads real-time voltage, shows battery health and indicates whether the alternator is charging correctly. The unit is powered by the battery under test and weighs 81 grams.

Suits DIY owners and mobile technicians

It suits anyone who wants a quick pass-or-fail indication without a workshop load bank. The simple LED readout works at night and the colour-coded clips prevent reversed connections. It cannot perform a timed load test or print a report, so professional garages needing documented results should look elsewhere.

Single specification: 12-volt only

The tester operates exclusively on 12-volt systems. If the vehicle uses a different voltage the readings will be invalid and the analyser may be damaged. Verify the system voltage before purchasing.

Questions about this item

What does the 12 V reading tell me about my battery and alternator?

The tester shows real-time voltage so you can see if the battery is fully charged, overcharged, low or empty, and whether the alternator is keeping the system in the correct range.

How does the analyser connect to the vehicle electrical system?

It uses simple red and black clips that attach to the positive and negative battery terminals for a direct 12 V connection.

Will the unit fit in a glovebox or tool tray?

At 4.53 by 2.75 by 0.79 inches and 81 grams it is small enough to store in a glovebox or standard tool tray.
