Originally posted by Docrwm My old Panasonic P&S had a way of telling what battery was inserted (panasonics way of maximizing profit by forcing use of their branded battery). The Washabi brand battery was the only one that would work in the camera that was not sold by Panasonic. So far they have worked fine in all my cameras. All I can say is that Pentax does NOT make batteries.
Thats the way my old sony was. If it wasn't bad enough the camera was $800, then you get nailed $60 a piece for the batteries (reports on several forums stated that most aftermarket ones would not work right and the camera would just shut down with a full battery). I did manage to get 3 with a $ off x size purchase and got 3 for the low $40's ea. If that wan't bad enough, then I had to get a sony memory stick which was about $100 for a one gig (if I recall right it was double or more the cost of a CF card and there were only sony, lexar, or sandisk even made).
