What it tests

The Lianshi 100 A Battery Load Tester evaluates 6 V and 12 V lead-acid batteries in cars, vans, boats, trucks, SUVs, motorcycles and ATVs. It measures open-circuit voltage and applies a fixed resistive load to reveal true cranking capability. The tool is powered by the battery under test, so no separate supply is needed.

Deciding specification

A single toggle switch engages a 100 A load for 12 V batteries or a 50 A load for 6 V batteries. The built-in voltmeter reads with ±0.3 V accuracy while the load is applied, giving an immediate pass-or-fail indication of battery health.

Behaviour under load

The tester is rated for a maximum 10-second load hold; the perforated metal housing vents heat during that interval. Copper alligator clips with insulated handles maintain a secure connection while the operator watches the colour-coded display for a steady voltage reading.

Questions about this item

What does the 100 A fixed load actually do when I test a 12 V battery?

It draws 100 A for up to 10 seconds to simulate starter motor drain so the voltmeter shows how the battery holds voltage under real cranking load.

How does the built-in voltmeter limit what I can read during a load test?

The analog voltmeter reads to ±0.3 V accuracy and is scaled for 6 V and 12 V systems, so it shows state-of-charge and voltage drop but not cold-cranking amps or internal resistance.

Will the 32 cm by 15 cm by 6 cm case fit in my tool drawer and how do the clips reach the terminals?

The tester measures 32 L x 15 W x 6 H centimeters and comes with heavy-duty alligator clips on rubber-insulated handles that clamp directly onto top or side battery posts.
