Hey gang,

I just received some new Blackberry 7105T devices. Most came with a blue battery (C-S2). One of them came with a BLACK battery (C-S1).

Is one better than the other - or offer a higher mAH rating?

Thanks,

No, the blue batteries will work in the 7100,7105 7100i, 8700 and 7130, the CS1 batteries will only work in the 7100 and 7105

If you put a CS1 battery in one of the new phones it will give you an error and won't let you turn the phone on.

C-S2 battery is the newer version it is *supposed* to be 100mAh stronger as well.
