Hi Mac
You did not say what is the history of these batteries or how they are charged.
They accept an unusually low charge current; that means long charge time.
They may not be fully charging in a solar day.
This would have been apparent from the start of course.

Hey wrenches,
Does anyone have any advice for troubleshooting Aquion batteries? This
particular stack is an Aspen 48M-25.9. They are losing power on a nightly
basis. I'm not seeing much technical literature out there and I'm not
familiar with these batteries.
Are there any common failures? How do you safely open the container to
check parallel strings. It may not be worth digging too deep but I'd be
interested in other opinions and experiences out there. Glad I didn't sell
them to him!
Thanks
