6V/12V dual-voltage load tester

The QEUOBUE battery load tester evaluates 6V batteries at 50 amps and 12V batteries at 100 amps. It checks battery health, starter motor current and charging system performance in one procedure. The analogue pointer gives an immediate visual reading. Red and black alligator clips ensure a secure, polarity-clear connection.

Replaces guesswork and single-voltage tools

Technicians who previously relied on voltage-only checks gain a true load test that reveals capacity loss under stress. The jump is worth it when a vehicle shows slow cranking or intermittent no-start symptoms despite a healthy resting voltage. It covers most sedans, trucks, SUVs, motorcycles, RVs, boats, ATVs and lawn tractors.

Not for buyers who need data logging

The analogue display requires the operator to interpret needle position manually. There is no digital output, memory function or software interface. Workshops that must document every test result for fleet records will find this tool insufficient. The compact 11.33 by 4.29 inch frame and 2.31 pound weight make it easy to store in a vehicle toolbox.

Questions about this item

How much space does the 11.33 by 4.29 inch tester need in a toolbox?

The unit measures 11.33 inches long by 4.29 inches wide and high, so it fits in most standard automotive tool trays or glove compartments.

What is the correct clip order when connecting to a 12 V battery for the 100 A load test?

Attach the red clip to the positive terminal first, then the black clip to the negative terminal; reversing the order can cause a spark or damage the meter.

When should the alligator clips be replaced on this 2.31 lb tester?

Replace the clips if the jaws no longer grip tightly, the insulation is cracked, or the spring tension has weakened enough to slip during a load test.
