If you do not know for absolute certain that this is a genuine OEM battery, I would suspect the battery, "end of story."

Here's my experience with a fake counterfeit (advertised as real) Canon charger. I wrote a VERY VERY rough email to the seller and told him he had 24 hours to refund my money, before I contacted the State Attorney General and a few other people. I had my refund in about an hour

This POS actually had a WEIGHT inside to make if feel "real."
