Has anyone used generic lithium ion batteries for their digital cameras?

Im concerned that if I buy the cheaper ones they'll not last very long and be a waste of money. What have you experiences with them been?

go to yahoo shopping
try to stay with major brands

I prefer to use rechargeable nickel metal hydride (NiMH) batteries. I have four sets, more than enough to last all day, and I recharge them overnight.

No. They will void the warranty on your camera. Many do not meet the specifications as set forth by camera manufacturers.

I have had the discussion with Mamiya, Nikon and Canon reps and they all say the same thing; "Don't do it"

NOTE on AA's: Current compact digital cameras that use AA batteries are optimized for Ni-MH rechargeable ... they are the only ones that will provide any good performance.

The other thing has is you have to use good power management ... keeping the LCD off a much as possible is the first thing to do

When you say lithium...remember you want the ones you recharge. The ones that do not take recharging are only a little better than regular alkalines, and not as good as NiMH rechargeable batteries. Not even close.

stay with brand name batteries of your camera. it will void the warranty if you use generics and something bad happens
