I just got a brand new Impres battery for my 7550. (PMNN4409AR) I put it on my impres charger and charged it completely before use. I get an error that says "Wrong Battery". It flashes on screen every 4 seconds. The battery info indicates that the first charge was the day I got it in the mail and the service life is 100% Can someone tell me what's going on here? Thank you!
