So I'm not sure when the battery in my MBP decided to get more articulate, but now it's expressing itself in more worrysome ways, like telling me "No, I don't care what you say, I don't wanna charge and you can't make me!" Of course, it actually says (Not Charging) in the menu bar. This happens at times seemingly unrelated to how full the battery is or how long the machine has been plugged in. My battery has 79 cycles on it, and is at 97% health. Unplugging and plugging back in the magsafe works sometimes, but with no pattern. I liked it when my MBP did whatever I told it to.
