Hmm when put like that I can only hope I didn't make a bad move with this battery. All I'm looking for is to get through a eight hour day without the constant need to charge.If you feel that getting approx 45% more battery (assuming the 2200 is accurate) will be enough to last you through the da, go for it.

I just ordered it a minute ago and you may be right. Why would they sell the exact same battery under two different mah labeling though.Looks just like the 3500mah battery and cover I got off ebay for $10 shipped
