Answer to: Battery or charging portNot the battery, not the charger... its the charging port! Apparently there is a slight difference in the diameter of that cheezy, tiny tip. The port hole is too large for most charging tips, doesn't matter if you get the charger from Moto or 3rd party. I have tried five; found one that works, but it is a 12v DC charger... so I plug in at night in my truck and its charged the next day. Pain; but Moto wont acknowledge the problem - check any forum... but Moto will look at for $150!
