Does anyone know what the best kind of batteries to use in a digital camera?

Rechargeables are the best, but spend the money and get a good brand, its worth it.
However, if you need to run out and buy disposables, you have to get either Duracell or Energizer brand, any other brand will not last more than a few pictures. The name brands are strong enough to last for the duration of a party, but not much longer.

Energizer rechargeables.

I don't know but I'll be watching to see what you find out cause the batteries in mine don't seem to last very long.....

In critical situations with flash, use alkaline batteries, they will cycle the flash quicker, else use rechargeables. Keep an alkaline set around for spares, when you need the camera, the rechargebles may not be so fresh. Good Luck!

it depends what kind of camera you have and what kind of batteries it accept. But lithium ion rechargeable batteries are the best.

Many cameras use different batteries. Many brands including sony uses , it's own proprietary batteries. Some brands you find in some general stores for cheap uses AAA, or AA batteries.
You should be able to open the battery cover and see what kind of battery it uses!! If you can't see the battery at all, then it's a non-replaceable battery that will last for couple years or a little more. Usually such cameras are the really cheap ones (Less than $50) you can pickup in some general stores.

Rechargable are the best for the camera. But always have a set of alkaline just in case you run low because digitals drain batteries fast. Also, don't keep the batteries in the camera when you are not using the camera. It's not good for either the batteries or the camera. Leakage will ruin a camera and as expensive as those things are. Good luck.

Typically it is alkaline batteries. In the process of being used, it does not use up part of the battery case to make the electricity. It reduces the chances of the battery leaking inside the camera.

I have had good experience with rechargeable batteries, but I would go with the camera manufacture recommendations.

When it comes to power, the ability to use a variety of battery types can be more important than any single type a camera may use.

For instance, lithium-ion rechargeable batteries generally last the longest, but if you're out in the woods, you have no way to recharge them, and you'd probably rather have a backpack full of disposables.

Your best bet is a camera that interchangeably supports rechargeables and long-life disposables.


Model-specific

Batteries designed specifically for a particular model or product line.

Chemistry: Lithium-ion or nickel-metal hydride (NiMH)

Advantages:

鈥?Tend to last the longest.
鈥?Make ultracompact designs possible.
鈥?Allow for more intelligent battery gauges that more
accurately measure remaining capacity.
鈥?Better for the environment than disposables.
鈥?Less expensive in the long run than disposables.


Disadvantages:

鈥?Require electricity to recharge.
鈥?Need to keep charged extras on hand.
鈥?Can't use in other cameras or electronic devices.
鈥?Don't always have third-party alternatives.


Universal rechargeable

Rechargeable batteries that adhere to standard conventions and sizes.

Chemistry: Nickel-metal hydride (NiMH)

Advantages:

鈥?Long-lived.
鈥?Better for the environment than disposables.
鈥?Can be bought from many sources.
鈥?Less expensive in the long run than disposables.


Disadvantages:

鈥?Usually require at least two AA-size units to power a camera, which adds to weight.

Disposable

Single-use batteries adhere to standard conventions and sizes.

Chemistry: Lithium, alkaline, oxy-alkaline

Advantages:

鈥?Lithium tend to last the longest and
make cameras speedier.
鈥?Readily available in stores.
鈥?Light.


Disadvantages:

鈥?Alkalines don't last long.
鈥?Not good for the environment

For rechargeable at a resaonable price, I'd use NiMh types with a mAh rating of 2500. There ARE LiON rechargeable batteries out there but they're still very expensive... in the professional photographer who-can-write-them-off range.

For non-rechargeable AA's the Energizer E2 LiON are a good way to go.... up to 4x the life of a non-rechargeable NiCad
