I had post early on battery issues where it just goes on hibernate with 40% or so left (about 40 min) and to start it back up with 0%

I'd updated bios to the latest version and now when i plugged in the charger, it goes up to 100% in less than a minute. It's actually not at it's 100%. Now it won't even last a minute.

Haven't done it, but will downgrade the bios version would fix it?

I like how I answered my own question. Funny how I got my answer. I was doing a search where I came to my answer and they refer to this site. Of course, I didn't get any answer from here.

My answer is: New Bios is not compatible with the battery. Suggestion is to flash it back. Sound good to me.

I'm glad you figured it out.
