Default [Q] NST replacement battery will not charge

The original battery in my Nook had gotten to the point where it would only run for a day or so. I ordered a replacement battery and installed it. The system came up and indicated a 85% charge. Put in on the charger for the evening and then started using it in the morning. After more then a month of use the Nook indicated it was getting low so I placed it back on the charger. It was then I noticed that while it detected it was on a charger (got the large battery icon) the device/battery never switched from 'discharge' to 'charging', only to 'not charging'. Left it on over night but no change.

Thinking I perhaps had a bad battery (and not being able to return it) I purchased another one from a different source. Upon installing this one (at a 75% charge) I noticed it would show the same thing 'not charging'.

Putting the Nook original battery back in made everything happy.

I have tried different cables and power plugs, reboots, hard reboots, pulling the battery holding the power down for 60sec, even doing the factory reset re-register. Nothing seems to help.

Has anyone else seen this type of behavior with a new battery?

Possible that both are bad? Or is there some value that is not getting cleared?

Any help or pointers will be appreciated.

Thank-you
