No sprint's are a little white with red lines crossing. Like a bunch of X's it will BLEED out and turn a PINKISH/REDISH color. I got a battery for my TP1 that is like that I will take a pic and post it.
EDIT: Here is the
BAD BATTERY with Sticker ACTIVATED
And here is the
Good Battery with Sticker
NOT Activated
Sorry had to take pics with TP2 so they aren't 10MP, lol
