Charging issue with Xantrex 2000

Yahoo Message Number: 97575
My Xantrex sometimes says my batteries are only 74‰ charged, even though my batteries are fully charged (as measured with meter at no load). It goes into absorption charge at 14.4 volts, 10-12 amps and "time left to charge" reads 00.00 on the remote. It may charge like this for maybe an hour or more. Anyone have this issue and a solution? TIA.

PS. I have two size 8D LifeLine batteries that are 20 months old.

You need to check the battery voltage at the batteries. Let the batteries fully charge then remove one battery cable from each one. let them rest for 24 hours then measure the resting voltage. This is the best way to check AGMs. If you want you can do one then the other one. If one is failing the battery charger will go back into absorb to bring it back up. Worth a try.

Thanks Mike. I disconnected both batteries, and after 20 hours, both read 12.8 volts.
