I was going by the numbers that I found in the instruction sheet of my charger, apparently they are arbitrary. Actually, I just Googled and found some at 2700 mAh, so in that respect you are correct. You may well be correct on the rest, but I was going by a discussion with a Radio Shack salesmen, who I had trouble to get him to even admit that their brand of IC3s would even charge properly in my old Ray-O-Vac charger. That and the fact that one article that I Googled on this type of charger, said that it had some kind of automatic switch to sense IC3s which delivered the current at the same voltage but at a higher efficiency...whatever that means.

With the charger that I have, it takes 8 hours to recharge the 1300 batteries, so I would guess that would come to about 16 hours for 2600. Obviously, the 15 minute charge time for my old batteries would only be a thing of the memory if I used that charger. From your comments, I would assume that a 15 minute charger of a different brand would be good to go, so I'm going to find one.
