Portable 6 and 12 Volt Battery Load Tester

The NEIKO 40510A is a handheld analyser for checking 6 V and 12 V lead-acid batteries in cars, vans, boats, trucks, motorcycles and RVs. It applies a fixed resistive load so you can see how the battery behaves under starter-motor current. The tool is aimed at DIY owners and mechanics who want a quick go/no-go verdict without a digital scan tool.

Fixed 100 Amp Load for Sustained Testing

A 100 A load is applied to 12 V batteries rated up to 1000 CCA, while 6 V batteries receive a 50 A load up to the same CCA rating. The load switch must be held for a maximum of 10 seconds per test to limit heating. Voltage accuracy is stated as ±0.2 V, giving a repeatable snapshot of cranking health rather than a momentary surface-charge reading.

Clamp-On Connection With Anti-Spark Switchgear

Copper clamps with colour-coded rubber grips attach directly to the battery terminals. An internal anti-spark switch isolates the load until the button is pressed, reducing the chance of arcing. The analog meter is encased for protection, and a top carry handle aids portability. Buyers needing automatic pass/fail logic or digital data logging will not find those functions here.

Questions about this item

Does the 100 AMP load test generate noticeable heat during repeated use?

The tester applies a fixed 100 AMP load for a maximum of 10 seconds on 12V batteries, so heat build-up stays minimal during normal diagnostic cycles.

What battery terminals must be accessible for the copper clamps to connect?

The red positive and black negative rubber-grip clamps need direct access to the battery posts on 6V or 12V automotive batteries.

Will the analog meter read accurately on a 6V motorcycle battery rated below 1000 CCA?

Yes, the unit switches to a 50 AMP load for 6V batteries up to 1000 CCA with a voltage accuracy of ± .2V.
