"Uh oh. So it looks like T-Mobile’s Windows Mobile-based Wing handset might be having some battery troubles. Wing owners have been quietly receiving replacement batteries in the mail. The new batteries are manufactured by Celxpert, which marks a departure from the original Dynapack-sourced juice packs. The new batteries are accompanied by a short note that reads: T-Mobile and HTC are providing a replacement for the T-Mobile Wing battery made by Dynapack at not charge to you due to rare occurrences of the battery overheating."

Hmm, apparently T-Mobile's "Fry your eggs on your Wing" promotion didn't work quite well. Who knows how problematic the batteries are (Anyone here have hot wings? </bad joke>), but if it wasn't an issue for you, you may be receiving an extra battery. Of course I'd use the new battery as your primary and save the potential burn-you-up battery for an emergency.
