Comments about Dantona® 3.7V/1200mAh Li-ion Battery for Samsung® Blackjack™:
Bought this as replacement for the Samsung Blackjack II battery...which was at the point of needing to be charged 2-3 times a day. I used this new one as directed, letting it deplete all the way and then recharging three times as suggested by instructions. However, this new battery performs no better than my old worn out battery did. I find myself needing to recharge 1-2 times a day. Kind of hard to do when traveling by air, etc.
