content: my first panasonic 2563 works great...this 2583 won't hold a charge for more than 10 minutes talk time...and it's only two weeks old!!!!!!!!!!customer service offered to replace it with a refurbished model when all i'm looking for is a new battery...i paid top dollar so that i could trade it in two weeks later for a refurbished unit...........i'm very dissapointed with them...never another panasonic.
