ATC NIMH Cordless Phone Battery for Panasonic HHR-P103 Dantona BATT-103 3.6V 800mAh Rechargeable

I've had these for a couple of months now. Historically, once the factory cells died I've gotten about 2 weeks of life out of replacement batteries. These are working like the factory batteries and have restored my favorite phones to their original talk-time capacity. Very satisfied.

not much else you can say. It had a charge in it when I got it, so the phone worked again. Has been staying charged up ever since.

Works like a charm.
