I just looked at the Lifeline webpage
http://www.lifelinebatteries.com/manual.php
here is a quote:
"Conditioning/Equalizing Charge: 15.5 volts for 8 hours
Conditioning/equalizing should only be done when the battery is showing symptoms of capacity loss. If conditioning/equalizing is necessary, first go through the normal charge cycle. Once the battery is as fully charged as possible, start the conditioning/equalizing charge. "
I always thought that you couldn't/shouldn't equalize AGMs. That's good to know, may give a few more years service!
