I too have one of the Rayovac 8 cell chargers and use it a lot. I bought it at Wal-Mart last Christmas. The only problem I have is that it doesn't sense when thay are done. I usually only leave batterys on there for 1 hour. I use it a lot for charging AA nimh cells for my digital camera. I still can't beat my very old Turbo-30 for charging the radio packs as well as my race packs. And now that Tekin is back I am going to send my 112-c in for upgrade and use it also for race packs. I might even try it on AA packs for transmitters.
