I think my assia batteries are rated at 1150, though I think they have new ones that claim 1250. I don't think they have that much more capacity than 900mah energizers, but they do hold a good charge and have been able to be charged in my 15minute charger. They've worked out for me, I would buy more.

I got them off of ebay. I'm not sure exactly who sold them, but they don't advertise them as assia. I think you have to look at the pictures or something to figure it out. It might help to search for 1250 with AAA as well.
