Calibration always cancels itself?

[Anonymous user]

I'm using a SmartUPS 1000XL with battery pack.

When I try to run a calibration, it inevitably comes back as "cancelled" after a while.

The batteries are old - circa 2004. Initiating the calibration shows immediate 47% capacity remaining. Could the age of the batteries cause this problem?

The quick answer is "yes".

The batteries are not maintaining the load long enough to get a run-time calibration.
Are you not getting any battery warning?

Depending on the environment, 6 years can be a long time for batteries.

No battery warning (but the unit is silenced as it's in a cubicle farm).

I will ask the boss to finance a couple of batteries for the unit.

(edit: I will try again with lowered sensitivity to line voltage fluctuations)
