I remember seeing somewhere (facebook maybe?) that Eric mentioned they have 2 different suppliers for their new packs. The batteries with the larger chrome numbers on them are from one supplier, and the labels with the smaller matte/white numbers are from a different supplier. I believe all of their older batteries were from the ladder supplier, and the chrome ones are new from this year. Are the two types you have with different stickers?

But hopefully EA see's this and can chime in.
