These batteries can't be new. I purchased one and it didn't hold a charge for more than 4 hours. I e-mailed the company and they sent me another battery right away (awesome customer service!) The new battery has to be charged every night, but it's much better than the one I had. I would buy this item again, because I saved about 40 dollars and know that if the battery doesn't work I can get another one with no problem.
