Load test is not a CAPACITY test – not at ALL.
My start battery is a 35 AH gel cell and it reads very well with my
100A load tester or the engine starter, which is 125 amps or so.

The starter motor can be used for a load test. Just measure the
voltage across the battery terminals while cranking. performs a basic
load-test of the battery, using the vehicle’s starter motor. This test
is done with the engine cranking. Use care to keep the voltmeter test
leads from contacting moving or hot engine parts.
Tool required: Digital Voltmeter, set on DC Volts
Test Lead position: across battery terminals.
While cranking, read the voltmeter. If the voltage reading is
below the minimum listed in the following chart, replace the battery.
Be aware that other possible causes of low readings in this test
are a failing starter motor or an engine with mechanical problems.
