Have changed mine several times no problems. Hugh

A proper charger will monitor the charge voltage and look for the small V drop as the cells reach full charge,regardless of the original charge left on the cells,maximizing cell life. That's why they are "smart" chargers. And from what I've read,you can leave the pack on the charger even after it is fully charged. No "forgetting" and overcharging. -- Jim Yanik jyanik at kua.net
From: Ken G. on 25 Aug 2005 23:42 Yes i have . I have an older 3 head shaver and removed the 2 old AA batterys and soldered in 2 ordinary Hi-MH AA cells about a year or so ago and the thing has worked just fine , it does not overheat or act funny in any way .

I don't remember the number, but I do remember being amazed at how low their battery prices were. I'd just been thru the hassle of replacing cells and would have just bought them from Norelco had I realized they were affordable.
