WUQ BT-100 100 Amp Battery Load Tester

This WUQ BT-100 is a battery load tester and voltmeter designed for 6V and 12V lead-acid batteries up to 1000 CCA. It suits automotive owners, marine users and small-engine operators who need a portable tool to verify battery condition and starter motor draw on cars, motorcycles, ATVs, boats and lawn tractors.

Thermals Noise and Power Draw

The durable steel case features a baked enamel shell and ventilation to stay cool during a load test. A rubber-insulated carrying handle provides a comfort grip while the unit dissipates heat passively without a fan, so operation stays silent. The tester draws its test current directly from the battery under test and requires no external power supply.

100 Amp 12V Load Test Capability

The single specification that decides fit is the 100 Amp load test for 12V batteries paired with a 50 Amp test for 6V batteries. Buyers needing higher current capacity or automated digital reporting should look elsewhere.

Questions about this item

How do I connect the clamps and which rocker-switch position do I select for a 12 V battery?

Attach the red clamp to the positive terminal and the black clamp to the negative terminal, then flip the top-mounted rocker switch to the 100 Amp position for a 12 V test.

What parts will wear out and need replacing after repeated load tests?

The heavy-duty color-coded clamps and the internal load resistor are the components most likely to degrade with frequent 100 Amp cycling.

At what point does the steel case ventilation limit continuous testing?

The ventilated steel case is designed to stay cool during a single 100 Amp load test; back-to-back tests without cool-down time will hit the thermal limit first.
