Has it ever been subjected to freezing temperature?
Tell about the host? Make/model/age.
It's unlikely a cure can be found, but do try the drain/calibrate if your laptop supports it. I can't tell since you didn't tell.
And in closing, they are good for about 500 full charge/discharge cycles and then the rest is gravy.
Battery power last only about 20 mins it is only about 7 months old. It will go from 73% to 7% in just seconds and shut down. Any help would be appreciated especially since I just bought the battery only months ago.
