It is common for an UPS to have different phases of charging, with the charging current tapering off at the end.

Which driver is this?

It is possible that there is more information that hasn't been mapped to a NUT variable in upsc, but there really isn't a lot of other standard information to convey. Some UPSes will report a status that we map to the "RB" (replace battery) flag in ups.status.

Lead-acid batteries are good for about 2-5 years in an UPS.
