Battery tester for 12 V lead-acid systems

The WUQ BT100 is a handheld 12 V battery analyser that reads state of health, state of charge, voltage, current and rating on regular flooded, AGM flat plate or spiral, EFB and GEL batteries rated from 100 to 2000 CCA. It powers up only when the clamps are correctly attached, so no separate charge is required before testing.

Suits owners and workshops checking 12 V starter

The tester covers cars, motorcycles, trucks, RVs, ATVs, SUVs, boats, yachts, lawnmowers and golf carts with 12 V lead-acid batteries in the supported CCA range. Buyers who need to diagnose 6 V systems or lithium chemistries will find the analyser unsuitable for those tasks.

Three-function test with colour LED feedback

A single unit runs a battery health test, a cranking test and a charging-system test, then shows the result through three coloured LEDs and a menu-driven display. Premium copper clamps include polarity-reverse prevention and spark-proof construction for a safe connection every time.

Questions about this item

What type of 12 V lead-acid battery must I have for the BT100 to read it?

The tester works with regular flooded, AGM flat plate, AGM spiral, EFB and GEL batteries rated between 100 and 2000 CCA.

Will the tester draw power from my vehicle's own 12 V system while I keep the old battery connected?

No, the BT100 powers on only when its copper clamps are properly attached to the battery under test, so it does not rely on the vehicle's electrical system.

How do the three coloured LEDs tell me the BT100 has finished a health check?

After a test the LEDs show the result — green for good, yellow for fair, red for replace — giving an immediate visual confirmation.
