I definetly changed it.
Thanks for all the info so far.
My batteries do have a dual green ring aroud the top. I bought these batteries as I said before cause they worked fantastic in my digital camera. I think I'll keep charging them the way it's been going. I'm getting just over 4 hours now, so they are getting better. In the meantime I'm going to be looking for a new fancy charger. Anyone know where to get either the Powerex or La Crosse charger in Canada?
