Which digital camera of battery type is better: Rechargeable Li-ion Battery or AA Alkaline batteries?

You get lots more shots using AA rechargeables(NiMH on each one of them). So, why are you comparing AA alkaline versus Li-ion batteries. I know of no one who's camera uses AA batteries that uses AA alkaline. They use AA Rechargeable batteries and bought themselves a charger.

I am assuming since you are comparing AA Alkaline to AA Li-ion batteries.

If so, these won't be a suitable substitute for your camera.

Rechargeable Lithium-ion batteries are a different chemistry from non-rechargeable Lithium (Lithium Iron Disulfide) batteries, which can confuse a lot of people.

Li-ion AA batteries have a voltage of 3.6V per cell, whereas typical AA batteries (Alkaline, non-rechargeable Lithium) batteries are 1.5V ( or 1.25V in the case of NiMh). If you put a set of 4 Li-ion AA batteries in your camera, you risk damaging it.

However, most camera rechargeable battery packs these days are Li-ion, but the camera and battery packs are designed to work together.

In general terms, Li-ion batteries are the best rechargeable batteries. Unfortunately, if your camera does not have a Li-ion battery pack, it cannot use them.

If your camera uses AA batteries, there are generally three different batteries you can use; Alkaline and Lithium (Lithium Iron Disulfide), which are non-rechargeable, and NiMH, which are rechargeable.

But there is a caution. The characteristics of the three battery types are different enough that the camera may or may not be able to efficiently use a particular type. Most cameras that allow the use of the three types have a setting in the menu to allow you to set up the camera for that battery. You will have to check your owner's manual for sure.

Lastly, some cameras may not be able to use NiMH batteries. Compared to Alkaline and Lithium batteries, NiMH batteries cannot supply as much current as the other two. This is different than capacity. Capacity is the amount of energy stored in the battery, while the current is how much of that energy can be supplied at any one time.

Your owner's manual should tell you if you can use NiMH batteries or not. Many owner's manuals also have a chart depicting how many photos you can take with each battery type. That way, you can determine which battery is most cost effective in your situation.

I am supplying a link to an article I wrote on AA batteries. While the article provides a recommendation on powering portable electronics found on a boat, it is generic enough to apply to camera gear.

If you use AA alkaline batteries you would have to replace them everytime they die down unless you want to spend around $12.00 buying a charger for AA alkaline rechargeable batteries. However AA Alkaline batteries are good to go out of the box.

Rechargeable Li-ion battery can be recharged usually by an adapter to an outlet or by USB (rarely). Rechargeable Li-ion batteries can constantly be reused until it becomes very old (5 years estimate).

The battery lasting time for both of them depend on how much power the camera absorbs to take a picture or take a video and how long or how much you use it. So their pretty equal on that point.

I would say Rechargeable Li-ion batteries because of the constant re-use you can apply to it. But if you dont plan on using the camera a whole lot and the alkaline costs less than the rechargeable li-ion, save your money and go with AA alkaline

The two types of batteries you mentioned are AA size batteries and proprietary Lithium Ion (Li-on) rechargeable battery. Both of them have strength and weakness. AA battery strength: - Available everywhere, if you ever ran out when you're on vacation, you can find them everywhere. - Lithium AA batteries, although expensive, last very long. - Rechargable NiMH AA batteries will save you a lot of money in the long run. AA battery weakness: - Very heavy. - If you don't use rechargables, it will cost you a lot of money buying batteries if you shoot a lot. - Alkaline AA battery will leak and it will spoil your camera if you don't take them out when not using it. Lithium Ion battery strength: - Lightweight, thin. Camera can be made very thin. - Holds more energy per weight (lighter, but store more power) - Usually charges very fast. Lithium Ion battery weakness: - Expensive to replace - Somewhat dangerous, if the protection/control circuit fails (rarely happens) it will blow up upon overcharge. - If you ran out of power, you can't replace it with generic batteries like AA batteries, you must charge them (so you must bring charger with you on vacation)

Rechargeable li-ion batteries last a heck of a lot longer, but AAs are better in terms of availability. You can find them more easily when you're on the go.

I think you'll find you'll get long life from the Li-ion batteries. Be sure to buy a charger that is for the specific batteries you get. Any mis match can cause over heating and in worst case, fire. Don't risk trying an old charger on new batteries.
