Charging issue with Xantrex 2000
My Xantrex sometimes says my two size 8D LifeLine AGM batteries are only 74‰ charged, even though my batteries are fully charged (as measured with meter at no load). It goes into absorption charge a...

The state of charge is depended on a few items.
1) how the internal shunt is connected
2) how many cycles (charge/discharge) you completed
3) whether or not your alternator is involved in the setup
4) whether or not solar is installed
5) the correct setup - better in the auto mode for battery capacity
6) fuel gauge cut out seting
Battery Capacity refers to the battery's reserve capacity in amp-hours. The RC7 approximates the battery state-of-charge (SOC) and run-time then estimates the battery capacity (Auto) over several charge/discharge cycles. However, setting the capacity manually assures a more accurate initial SOC and run-time calculations. The default setting is Auto.
The Fuel gauge Cutout menu sets the battery voltage zero percent state of charge (0% SOC) with no load. This is the point at which the battery has zero reserve amp-hours remaining. The Fuel gauge meter uses this number to determine the 0% battery state-of-charge voltage. The default is 9.5 VDC.
