Which type of batteries work best and last longer for digital cameras?

Rechargeables.

Lithium

energizer titanium.....expensive but well worth the price.

Rechargables. Get a couple sets so one is always ready to go. Otherwise you're just constantly filling up landfills. No batteries last long in that sort of application.

spend the extra money and get rechargable batteries. they last a lot longer in the camera than a regular battery, and you'll save money on batteries over time.

Lithiums (they economize flash pictures)theyre also lightweight

i would say the rechargable batteries would be good. try the rechargable duracells

the new 2700 range of rechargables

Yep, invest in a charger and get two sets of rechargable batteries. You'll save a ton of cash.

NIMH rechargables are the way to go, try and get the highest rating ie 2500 mah or better

If you live in the US go to Radio Shack, they have gd batteries

Lithium batteries work longest. Rechargeables, if your camera can use them, may be cheaper.

The Energizer Rechargeable 2500mAh batteries are by far the longest lasting. Wal-Mart sells a package deal with 4 batteries and a charger for $25. Pricier than others, but the batteries last the longest (and I have tried them all, rechargeable and single-use) and the charger is a quality one that will not overcharge or fry out your batteries.

The Energizer E2 lithium and titanium are also the best for single use, but honestly, single use batteries are a waste of money. I have been using the same batteries in my digital camera for the past months and I use it quite often.

Normal alkaline batteries just don't do it for digital cameras because of the high instantaneous current required to run a digital camera. (This includes all batteries such as "Duracell" and "Super Heavy Duty" etc) These types of batteries will appear to the camera to be flat even when they aren't because they just don't have the capacity to give the camera what it wants.

Some places still sell rechargeable Nickel Cadmium Batteries (NiCd), and these batteries cannot cut it for digital cameras. There are also rechargeable alkaline batteries and these aren't great either.

The only type of rechargeable to get is Nickel Metal Hydride (NiMH), and the higher capacity the better. This capacity is typically rated in milliamp hours. A medium capacity battery for a camera will have say 1600 MAH whereas a high capacity battery will have more than 2000 MAH. Some even go as high as 2600 MAH. Get the highest that you can.

One downside is that NiMH batteries go flat in the camera if you do not use them. In a camera that uses 2 batteries, this can happen in as little as a week.

My advice is get a couple of sets of high capacity NiMH rechargeable batteries (2000 MAH or higher) and use these as much as possible. Also however buy one or two sets of Lithium batteries (non rechargeable) these last a long time but are wickedly expensive. Have one set of lithiums for backup in case you need the shot but the rechargeables are all flat. Soon as you can put freshly recharged batteries in and again keep the lithiums in reserve. Unused lithium batteries will last for years.

Many cameras have a menu setting which can flatten the batteries for you prior to recharging. ONLY IF you are using NiMH batteries is this a good idea. Vendors tell you that NiMH are not prone to "memory effect" and therefore do not need to be totally flat before being recharged, but this is not true. NiMH batteries should be discharged before being recharged. If the camera can't automatically discharge them, then keep using the camera until it won't go anymore, then recharge them.

Hope this helps.

I buy my batteries from the link below
I buy the maha 2700's
they are the best

Either lithium [rechargeable or not rechargeable] or just rechargeable
