12V 100A Battery Load Tester

This battery load tester evaluates 6V and 12V batteries across cars, trucks, RVs and golf carts. It also checks alternator performance so you can verify the charging system in one tool. The brass-and-plastic body fits in a shock-resistant steel case with a carry handle. Heavy-duty copper-plated clamps ensure secure connections during testing.

1000 CCA maximum capacity and headroom

The tester applies up to 100 A of load and rates batteries to a maximum of 1000 Cold Cranking Amps. It comfortably handles typical automotive and light-commercial batteries within that range. Testing stops at the 1000 CCA limit, so larger commercial or industrial batteries fall outside its capability.

Upgrades from basic voltage-only testers

A simple voltmeter only shows open-circuit voltage and cannot reveal weak cells under load. This unit adds real load testing and alternator diagnosis, making the jump worthwhile when you need to confirm cranking ability and charging health. It does not replace professional workshop analysers that offer data logging or higher current capacity.

Questions about this item

Will this 1000 CCA tester safely load-test the 12 V battery in my older golf cart?

Yes, the tester handles both 6 V and 12 V batteries up to 1000 CCA, so it covers the golf cart battery without exceeding its limits.

How can I verify the alternator test function is working after I connect the clamps?

Run the alternator test with the engine running; the tool will indicate whether the charging system is performing within normal range.

Does the package include the heavy-duty copper-plated clamps and shock-resistant steel case shown in the photos?

The tester ships with the copper-plated clamps attached and the steel case included; no extra accessories are required for basic battery and alternator testing.
