“Is this compatible with the U52F-BBG6 model? It's the only thing remotely close to my model. I just didn't know since it says that it works with the U50Fseries, if my model was in that series? I really just need to replace my battery! It will only stay charged for 5 mins, no matter how long it's been plugged in. If this wont work, do you know which battery I should be looking for, or is there a universal battery I can look for on here? Thank you so much! ~Jessica”
