KAIHENG 100 A Battery Load Tester

This portable load tester applies a fixed 100 A load for 12 V batteries and 50 A for 6 V batteries. It suits DIY owners of cars, motorcycles, RVs and boats who want to check battery condition, starter draw and charging-system health without visiting a workshop.

Verify battery voltage and terminal access

Ensure the battery you intend to test is a 6 V or 12 V lead-acid type and that its terminals are clean and accessible for the copper alligator clips. The tester draws high current for up to 10 seconds, so confirm the battery can safely sustain that load before connecting.

Insulated handle and colour-coded clips

A moulded carry handle on the 22 x 10 x 15 cm body provides insulated grip during testing. Red and black rubber-gripped clips mark polarity clearly, reducing the chance of reversed connection. At 0.45 kg the unit is light enough for one-hand operation in a garage or at the roadside. || Users needing adjustable load steps, digital data logging or tests beyond 100 A will find this fixed-load analogue instrument insufficient.

Questions about this item

What comes in the box and what must I buy separately?

The tester arrives ready to use with built-in copper alligator clips and an insulated carry handle; no extra accessories or batteries are required.

Should I choose the 6 V or 12 V setting for my vehicle?

Select 12 V for cars, trucks, SUVs, motorcycles, RVs and boats — it applies a 100 A load; choose 6 V for smaller 6 V batteries where the tester applies a 50 A load.

What does the 100 A load current mean when I test a 12 V battery?

It draws 100 A for up to 10 seconds to simulate starter-motor demand; a reading above 13 V means good, 9 V to 13 V is normal, below 9 V indicates a defective or discharged battery.
