While my B2700 persistently refuses to give up the ghost, it is getting harder to come by functioning batteries. With no-name batteries I had already made good experiences with other models and especially with cameras. However, this one is useless (at least the items did I get). He worked a few meager signs of life, but then went for a week nothing. No peep. No charge possible. For a return to cheap, meaningless. After that I could elsewhere get a battery replacements, the already no longer applied, however the full power. So far, he function and the actual original still halfway. and then?
