My Logitech V400 mouse declared that it's single AA battery has gone critical on Friday. It's been almost a week, and the battery is still sufficiently alive to power it. Now, while I do appreciate the early warning (which allowed me to comfortably acquire a replacement), I wonder if 'critical, replace immediately' was the proper message to send. After all, had I listened, I would've thrown away a battery that still has a week (or more?) worth of juice left in it.
