Loaded V vs OCV for DOD Lifeline AGMs ?
Anyone explain this please? They have 50% at 12.15v loaded at the 20hr rate, but say it is 12.18v OCV. Shouldn't the loaded voltage be farther down from the OCV than that? (Appendix in link) h...

This is why I recommended BFL talk to Concorde.
By FAR the easiest way to query an AGM battery to see up is to fully charge the battery a week after you get it./// amps and volts twiddling to your heart's content.
later, down the line, repeat the tests then compare to brand new.
Example wait one hour before disconnecting a fully charged AGM but tweak the voltage up .5 volts for that one hour. Disconnect and take surface charge volt readings for the next 2 days. What do you see? Many spurious observances can be had with non standard testing. Gains in OBSERVED can be disqualified with a carbon pile load tester. AGAIN! Test when new compared with subsequent tests.
