About 3-4 months ago I noticed one of my batteries had a bulge at the bottom of the battery after charging, so I put that to one side and purchased a new one, yesterday I found the battery with the bulge in a cupboard and there was no bulge, so I charged that battery and it has all 4 light and no bulge, I have not put it in the MP yet, do you guys think it will be ok to use or not.
