If you have a recent enough version of NUT, megatec supports a
parameter "battvolts" where you can specify the battery voltage when
the UPS is fully charged, and the voltage when the UPS is discharged.

You can run "megatec -DDD yourups" while powering a lightbulb or
another non-important device, disconnect from the wall and let the UPS
drain the battery until it shuts itself down. Then send me the output
and I'll help you find the values from it.
