I just picked up a mint XPR7550e with PMNN4491 battery, date code 1723. When I first got the radio it said "Recondition Battery" under the battery info display.
I have now twice discharged the battery with a few hours use, put it in the charger, forced a recondition cycle... and still saying Recondition Battery.

I am starting to think I need to harass Motorola since it seems like the battery is a dud - but wondering if there's any tricks I have been missing?

Also firmware on radio was 2.7, upgraded to 2.9, and charger firmware is 3.9
