Will the 84.0 x 51.4 x 14.3 mm pack sit in the same battery compartment as the original P-P507A cell?

Yes, it matches the factory dimensions and connector layout so it drops into the existing compartment without modification.

Place the handset on its base; the charge indicator should illuminate and the phone should reach full talk-time within the normal charge cycle.
