Here's the charge curve used by the Tripp-Lite driver: http://boxster.ghz.cc/projects/nut/browser/trunk/drivers/tripplite.c#L456 Generally speaking, measuring the voltage to find charge is a bit problematic unless you take into account the amount of current flowing in or out of the battery as well (a real-world battery has non-zero Thevenin resistance, so it is not a pure voltage source). The best you can do is plot voltages over time (as reported by the UPS), and try to fit the curve. -- - Charles Lepple _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
