The procedure didn't work so well for me. After installing the new battery, I got the question mark over the battery symbol that others had. So I let the battery drain as suggested, and now after plugging the phone in to recharge, the Motorola "M" pops up on the screen like the phone is starting up, and just sits there. I tried charging overnight to no avail. The phone works with the old battery, so I don't know what happened.
