These must be fraudulent fakes. I can't believe Panasonic will ever release these batteries. The Revain advert says 700mAh, but the battery says at least 630mAh. They were packaged in clear plastic packaging with no Panasonic branding other than what was printed on the batteries. When you put them in the phone, he writes "Charge 7 hours" just like normal. But after a while the phone says "Use batteries". The batteries will eventually charge to the top of the gauge, but will drain quickly (about 45 minutes on a hands-free conference call). Have tried several batteries from the kit and all give the same result. Never had this problem with the original batteries which lasted 5 years except the time between charges decreased somewhat. I'm sorry I didn't look at the user reviews - there have been several people voicing the same complaint over the past few months. But I figured what could go wrong - these are Panasonic batteries meant to be swapped out in their own phones. And Revain sells them.
