Somewhere interesting
Unplug the MagSafe adapter, and let the charge drop to about 95% (or 90%, im not sure), it will then start charging up again.

It is not a 'bug', or a 'problem', you don't have to 'fix' it. It does that so the battery is not constantly charging whenever you unplug your MB/P from the MagSafe connector.

MBP stuck at 100%

My MacBook Pro is also stuck at 100% (when the adapter is UNPLUGGED) and 99% (when the adapter is PLUGGED in) It won't adjust the percentage at all. It does give me remaining life in minutes.

I have restarted, removed and replaced the battery, and reset PRAM.

Note- I am at 294 cycles.

Any other suggestions?

The voltage measurement on battery packs is not that accurate! (you cannot measure remaing capacity to within 1%). Moreover you don't want LiIon technology to be charged to 100% - kills the lifetime.
