agm capacity test
I've installed 2 8d deka intimidators in my fiver. Closing in on 15 cycles. Would like to do a baseline test so I will have something to compare to in the future. What would be the proper way to prefo...

My test is to first make sure the batts are full.
Then I get the 20hour rate by dividing the rated capacity by 20, so EG 300AH would be 15amps. Reduce the est full capacity for really cold temps, but getting the temp correction right is dodgy since some of that is supposed to be internal battery temp, not ambient.
Good idea, wrong EG.. (Should have used 500) He hs 490 amp hours of battery there (Very good Original poster,, nice package) so divided by 20 that is 24.5 amps..
A 500 amp load tester MIGHT be able to do that for 10 hours. but.. Frankly Id reather use light bulbs (About a dozen 1141's and trim from there)
Measure the voltage hourly.. You should hit 50 Percent just about 10 hours into the test.
