Battery charge versus remaining usable charge
This seems like a silly question, but I know it's actually complicated and may not be something anyone can really answer. That said, is there any way to know how long a set of batteries will last bas...

The only 2 things I can think of.
1) CO detector
2) stereo
I don't think it could be the CO detector since that should be using close to what a smoke alarm uses (1 9v battery per year).
I noticed that with the stereo off I can sometimes hear static coming out the speakers over the dinette. It's quiet, but I'm sure it's there (my wife Cinfirmed I'm not crazy).
