12 V 100 A and 6 V 50 A Load Tester

The Battery Tender 026-0020 applies a 100 amp load to 12 volt batteries and a 50 amp load to 6 volt batteries. It checks starter motor draw and helps diagnose charging systems. A colour coded display shows the test result at a glance. Rubber insulated handle and heavy duty alligator clamps provide safe connections.

Suits owners of cars trucks SUVs motorcycles RVs

Technicians who need to verify starter and deep cycle batteries up to 1000 cranking amps will find the tester covers the common vehicle range. It is not intended for battery chemistries beyond lithium lead acid AGM or gel. Users requiring wireless monitoring or data logging should consider a different instrument.

100 amp load at 12 volts and 50 amp load at 6 volts

The single specification that decides fit is the fixed load current paired with each voltage. If the battery under test calls for a different load value or a voltage outside 6 V and 12 V this tool will not perform the required test.

Questions about this item

Does the Battery Tender 026-0020 generate noticeable heat or noise when running a 100 amp load test on a 12V battery?

The tester applies a resistive load only during the brief test period, so it warms slightly but has no fan and produces no audible noise.

What must I already own to use the 026-0020 for a starter motor draw test?

You need a 12V or 6V starter or deep-cycle battery (up to 1,000 cranking amps) and the vehicle’s starter circuit accessible for the alligator clips.

Will the 026-0020 work alongside an older analog voltmeter I keep in the shop?

Yes — the unit’s color-coded display gives a direct voltage and load reading, so you can cross-check it with any separate voltmeter you already use.
