As you are making a purchase decision, we suggest that you take the time to read some En-EL3e Nikon Battery reviews in order to see what other consumers have to say about the product. Here are some user reviews to help you make your shopping decision:

This battery is backwards compatible with the D50, D70/70s, and is used in the D80 and D200. So if you have any Nikon DSLR and want a second battery, you want to get this one so that when you upgrade your camera you can use the battery.

This battery has built-in circuitry that tells you the actual charge status of the battery, and it is accurate. This is a big deal; *if you are using the D200 or D80* it lets you know when your really do need to switch batteries or charge up. This is the first battery I've seen that is accurate in this regard. Kudos to Nikon. (This feature does not work in the D50/70/70s but the battery otherwise works fine).

The new Nikon EN-EL3e battery is a slight update for the Nikon EN-EL3 provided with earlier dSLR models such as the D70. It adds a contact that allows new cameras to determine how much charge is left in the battery. The battery is grey to distinguish it from the black EN-EL3.

The EN-EL3e is backwards compatible with the EN-EL3: you can put it in your D70 or D50. The reverse is not true.

The number of pictures that the battery gives you depends on a lot of factors, including shooting style, LCD usage, and of course, camera. (The 2.5" LCD on the D200 will use up the battery much quicker than the smaller D70.) It is sufficient for a day of shooting. Unless you are using a D200 in some professional capacity, in which case, you'll probably be investing in at least one backup battery.

Over the years I've bought several off-brand batteries for my Nikon digital cameras. Now I will only buy Nikon brand batteries. Never had one fail. I am very pleased with how many shots you can get from the EN-EL3e.

I used my new Nikon D200 this past weekend at a Renaissance Faire in high heat, and the EL3e performed like a champ (as did the camera itself). I couldn't believe that I got through three full days of picture-taking (using fill flash after five pm or so) on one battery charge. I finally ran out of juice late on the third day, after approximately 500 exposures.

(One caveat: I don't use auto-focus. At all. Ever. So, you know, YMMV.)

I purchased an additional Nikon brand EN-EL3e battery for my Nikon D90. It works just as Nikon said it would. I feel confident using this product since it is the same as the battery supplied with my camera. Therefore I know I can expect the same quality as I get with all Nikon products. Buying off-brand may save you a few bucks initially but if the off-brand battery damages your expensive camera Nikon will not help you. The few bucks you might save buying an off-brand may just end up not being the bargain you thought you might be getting. Stick with the brand name.

I have used Nikon batteries for about 4 1/2 years. I also bought two cheap chinese imitations for 1/2 the Nikon price. They didn't hold up for 1/20 as much time, and I've read some inferior batteries are possible fire hazzards. One completely failed after 4 months.

Save time and frustration - buy the best available power for your Nikon camera. The original batteries last many years, and take hundreds of re-charges. I have Nikon batteries purchased back to 2004 that still hold good charges. I've taken over 30,000 shots during this time.
