I have a motorola w755 flipphone; it seems like you can't get a really fresh Motorola BT51 - cellular phone battery; they all must be already somewhat depleted as they are quite old, since this is an old cellphone. Is there a contemporary replacement equivalent for this battery? and if so, what is the model, etc?

thank you so much! this is the first link I've gotten to what appears to be an actual substitute--at first glance, and nice that it has a lifetime warranty; I'll check it out a bit more.
