What's interesting is it "appears" like Kodak may have two versions of the Pre-charged batteries. I brought it up in another thread, I've seen a "up to" 2500mah print on one package and "up to" 2100mah on another. The higher mah had a different color battery wrapper. The lower rated one is the one shown in your Walmart link (white).
I could have sworn I saw them (2500mah Pre-charged) at the stores, I am very tempted to grab one. Then I can snap a pic and post it here. The only thing I am beginning to wonder is if it was a packaging misprint but then the wrapper was a different color. Kodak's press release didn't state a 2500mah Pre-charged battery, just a 2100mah one.
Took a closer look at the 2500mah Kodaks and yep, I was mistaken, they are the standard nimh rechargeable ones, not the LSD batteries I had hoped for. Tricky as the packaging is almost identical to the LSD batts.
