I have had very good experiences buying from Amazon, until now. I bought this "new" battery to replace a battery that would only charge up to 2 bars. It arrived in a regular postal envelope (really?). I charged it for 10 hours and got 2 bars. I have tried multiple times to charge it and never get more than 2 bars. If you advertise something as new you are bound to deliver a NEW not refurbished product. This battery was obviously not new. The seller was ACC.
