The description and image are for the 2450 mAh batteries. I've had a few sets of these and they truly seem to deliver the rated capacity. I ended up buying a set of the "new and improved" 2300 mAh batteries in the store and they sucked. I got less than 2000 mAH out of them in a controlled test. I took those back to the store as defective and tracked down the 2450s here on Amazon. What arrived are the vastly inferior 2300s.Rather than get stuck with these crummy Energizers (since you can't get the good ones any longer), look for Sanyos.
