After reading all the threads suggesting that Centro batteries might be OK to use in a Pre, I picked up two OEM ones from ca-battery.com.

Bottom line is, they don't work. At first they behave like they are uncharged, then when left plugged in and charging long enough, they suddenly shoot to 100% and 2000+ mAh rating, then quickly go to a permanent "battery charging" screen.

I'm happy my Pre is still working. Maybe Centro batteries will work in the Pre, but these ones won't.
