WUQ 3180 100 Amp Load Tester

The WUQ 3180 is a portable battery load tester designed for checking 6 volt and 12 volt automotive batteries. It delivers a 100 amp load to determine good or bad status in roughly 10 seconds. The extra-large display includes a zero-adjust feature for clear readings. Heavy-duty copper-plated clamps ensure a secure connection during testing.

Capacity and Headroom

The tester applies a fixed 100 amp load and reads voltages across a 0 to 16 volt range. It comfortably handles standard cranking and charging voltage checks on both 6 volt and 12 volt systems. The unit cannot test batteries requiring higher load currents or voltages beyond the 16 volt maximum. A load safety switch prevents arcing during connection and disconnection.

Build Integration

Ceramic insulators and a chrome-plated ventilated steel case protect the internals during regular workshop use. The portable size allows testing batteries on or off the vehicle without permanent installation. No external power source is needed for the load test itself. Buyers needing continuous monitoring or data logging should look elsewhere.

Questions about this item

Will the 100 amp load test damage a 6 volt battery that I keep for a vintage vehicle?

The tester works on both 6 volt and 12 volt batteries and the load safety switch prevents arcing during the 10 second test.

How do I confirm the zero adjust on the extra-large display is calibrated before I test a battery?

With the load safety switch off, turn the zero adjust knob until the needle sits exactly at zero on the 0-16 volt scale.

Do the heavy-duty copper-plated clamps and ceramic insulators come attached, or must I buy leads separately?

The clamps and ceramic insulators are built into the chrome-plated ventilated steel case; nothing extra is required to start testing.
