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.

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. Minimum Battery Load-test Voltage Battery Temp Degrees F 9.90 100 9.80 90 9.70 80 9.60 70 9.50 60 9.40 50 9.30 40 9.10 30 8.90 20 8.70 10 8.50 [page2image39984] 0 Sent from my iPhone _______________________________________________ This list is supported by the generous donations of our members.
