Salut,

fine, thanks. always too short, but it allows to recharge
the battery enough to face the huge mail stack ;-)

a right choice.

FYI, nut hasn't yet a way to differientate the various possible
internal error. So we can only raise "RB" (Replace Battery)
for the moment.

does this unit suffered from lightning or something else?
Anyway, you'll be contacted by MGE support to deal with this point.

yes, the MGE support isn't 100 % complete, although
we have the best and more complete one in NUT ;-)
so, always use the latest release (2.0.2 for now, 2.0.3 soon)

the OFF status has been added for 2.0.2, as well as
the BYPASS status.

Notes on MGE units:
- you can have OL + OFF as OL means the UPS
is ONLINE and OFF means that the output are cut,
which are different (IIRC, I've got to clarify this for NUT)
- about the [DIS]CHRG, even if battery.charge = 100,
there is always a small consumption and thus a small
recharge needed. Other mfrs seems to not expose that,
while we do. Note that there are other case where it is
interesting to have that info, but it's on high end models...
- the above output.voltage validates that the output
are off (not feeding power == voltage 0). You can also
check on the front panel that the 2 plugs led are not light.
