I would suggest getting Nick's Battmon. That will give you more
information as to battery condition. It should be on UNNA.

It shouldn't be discharging that quick defiantly. However one thing to
keep in mind, a FLASH card does not draw power unless being read or
written to. And depending on the card, they often take more power to
write than to write. Wireless cards draw a LOT of juice and will kill
any battery quite quickly. But you only use that when plugged in, so it
can't be that.

That is a good monitor, but I still prefer Nick's.

Monthly? I think that is a over doing it a bit. I haven't done mine in
a year or two. Some even longer than that. I did redo a card recently
because I had problems with restoring just one soup. I reformatted the
card and restored everything and it went fine. So yes sometimes it is
necessary, but I don't think you need to do it monthly. Backups
definitely, and preferably more than that.
