I received a defective battery. The casing was split wide open even though the packaging was not damaged and it didn't appear that there was any mishandling in shipping. I believe that it was a manufacturing defect. The card in the box gave the website to go to for returns. On contacting the company, they refuse to take it back and refund me. They will do an exchange if I send it back, on my dollar, and send even more money to them (I guess that then I sit back and hope that the replacement isn't defective). The customer service representative that I communicated with just made excuses and was not sympathetic or courteous. I will not ever deal with this company again and advise against you doing so.
