This is not a NUT question per se ... or at least, I don't think it is.
I just replaced the battery pack in my HP R3000XR; the new batteries
were shipped with 90% charge, were at about 87% when they went in, and
were up to 98% charge the next day.
Last weekend, the server that runs NUT went down for no apparent reason,
wiping out its boot blocks, corrupting its boot archive beyond repair,
and forcing an OS reinstall. After reinstalling Solaris 10, NUT is now
reporting battery charge hovering between 40% and 42%. This is
puzzling, considering that it initially reported full charge, the UPS is
only under about 40% load and, the power has not gone out.

Does anyone with more experience with NUT or with this UPS model than I
know whether there's any kind of calibration I need to do after
replacing the battery pack, or have any idea why the UPS would have
suddenly dropped to around 40% charge after several days, with brand new
batteries, and just stay there? The battery pack voltage is nominal, so
I can't very well have had one of the new cells fail unexpectedly.
