Which battery do you prefer in digital cameras? Lithium Ion Rechargable or regular batteries (no charger)?

I know you can always get rechargeable batteries, but I hear that digital cameras use a lot of juice, so you'd probably have to have lots of sets. what do you think?

As a photographer I like using the battery pack that comes with the camera. The square type li-ion but for my flash i use disposable AA batteries. I used rechargeable AA batteries and after using them for a while thy don't keep a good charge and don't work good enough. I used to use AA rechargeable on my Kodak easy share but it always had the low battery indicator after taking a few shots. you can use a battery pack if your camera allows for it if not then you can use the disposable li-ion batteries. Depending on how much you use your camera you can try and see what works for you. Disposable batteries aren't cheap so if you want to try and see how the rechargeable batteries work for you then go on ahead. I just used my camera a lot so my rechargeable batteries died quicker then normal. I always have plenty extra no matter how much pictures i will be taking. So never leave with out extra batteries you don't want to miss that perfect shot.

I have used both, and found out that unfortunatly the Ion ones work longer, but are more expensive. The rechargable ones work but not long at all.
I would go with ion 2 they have to be the lithiam ion squared
the regular ones are not strong enough

I use Nickle Metal Hydride (NiMH) batteries for everything now. They are pricey, but have great power and last a long time if you remember to fully drain them before a recharge, and fully charge them each time you recharge them.

My digital camera has it's own rechargable batteries, which are also NiMH. I've had my camera for nearly 6 years now, and am still using the original pair of rechargables I bought with the camera. I think I may have to get a new set some time in the next few months. They don't seem to be holding a charge nearly as long as they once did. But, hey! Six years on one pair of batteries... not bad at all.

Lithium Ion are the best ones to use they last longer, but they are a bit expensive. Depending on the camera & the user even regular batteries can work well. What I mean by the user is that if you keep the camera display on the whole time as opposed to someone who doesn't, it won't matter what batteries you use you'll certainly cut down on their lasting time. Personally I prefer rechargable Rayovac batteries & I like to have two sets with me just in case. I haven't tried Duracell rechargables so I can't comment on them but in my opinion Rayovac lasts longer than Energizers recharagables. Whatever you decide to use just remember to turn off the cameras display when you're not using it & anyelse that drains the batteries when possible. If it doesn't need to be on then turn the camera off. If you have an AC adapter then try to use it whenever possible.

My camera has a lithium ion battery and I've been extremely happy with it. I just ordered a digital SLR that uses rechargeable AA batteries. I hope it's not a step backwards.
