Long-lasting for digicams Sep 13, 2008
These specific make and model of lithium batteries seem to be the longest lasting in your typical digital camera. I've discovered that not all lithium batteries are the same. Look for this EXACT model of lithium battery; other Energizer lithiums I've tried are not quite as good in digital camera use.

Match those batteries with the correct application for best results Jan 01, 2008
The Energizer L91 Lithium AA cell is a fantastic power source. For high-drain applications, it offers great advantages over ordinary alkaline cell and rechargeable NiMH cell. However, it is also very expensive as a disposable battery. So it is important to recognize the strength of L91, and use it only in applications that give you the best results. Otherwise you'll be wasting your money.
According to data sheet published by Energizer, the capacity of the Lithium AA cell (L91) is 3000mAh. This number remains nearly constant with load current. In comparison, the ordinary Alkaline battery (such as the Energizer E91 AA) is rated as 2800mAh, but only at a very light load of 25mA. At a heavy load of 1000mA (typical for a digital camera or flash unit), its capacity drops to below 1000mAh. This number gets even worse at low temperature. At zero degree C and 1000mA load, the L91 can provide about seven times more energy compared to the E91. This is where the marketing claim of "Last up to 7 times longer" comes from.
When used in a digital camera at room temperature of 25 degree C, the L91 is more likely to last 3-4 times longer than alkaline. This is enough to justify its price, which is also around 3-4 times higher than alkaline. However, in low-drain applications (such as smoke detector, wireless mouse or remote control) alkaline cells will last just as long at a fraction of the cost.
The L91 also contains much higher energy when compared to an ordinary rechargeable NiMH cell such as the Energizer NH15-2500. This is partially due to its higher terminal voltage of 1.5V, which is 20% higher than that for NiMH.
Energy stored in NH15-2500 : 2.5Ah * 1.25V = 3.125Wh,
Energy stored in L91 : 3Ah * 1.5V = 4.5Wh (44% higher).
Higher terminal voltage for L91 is especially advantageous in digital camera applications, because your camera flash will recharge up to 20% faster. An added benefit is that the L91 weighs only 14.5 grams (0.5 oz) each, compared to 30 grams (1 oz) for NiMH. So your camera becomes much lighter.
The NH15-2500, like all ordinary NiMH cells, suffers from rapid self-discharge problem. If you charge up a set of those cells and leave them in your camera for a few weeks, you're likely to be greeted by 'Low Battery' sign when you try to take a photo. The new generation of 'ready-to-use' NiMH cells such as SANYO eneloop and Rayovac Hybrid solved this problem by having very low self discharge rate. But they have lower capacity of only 2000-2100mAh.
Bottom line: If you need AA batteries for a long hiking trip, then L91 is obviously your best choice. For most other situations, I recommend using low self-discharge NiMH cells for lower operating cost.

great for flash May 26, 2006
nothing in the digital camera world drains the battery faster than the external flash unit for dSRL. my flash (Canon FX430) takes 4 AA batteries and requires changing perhaps every so often. since 4 AA batteries are kind of heavy to carry in my camera pack, and since the flash unit is absolutely crucial in photography, i cannot afford running out of battery on it! ever since i bought these batteries however i had the peace of mind that my flash won't die on me, period. the peace of mind allows me to take as many flash photography as i want without any mental burden. i know every time i turn it on it will be ready to go. amazing.

Whole new world Sep 13, 2005
Wow! I'm probably going to change the way I look at batteries from now on. We stuck two of these in our Sony digital camera and put two more in the bag to use when these ran out, and went on vacation for two weeks. I'm not sure how many photos we took in two weeks, but after culling out maybe 50 that we didn't want, we wind up with 206. Many of these were taken using the flash. During the trip, I downloaded the pics to my laptop about 3 times directly from the camera, and that also takes a bunch of power. Since the trip, there was a social occasion where my wife took perhaps 20 pictures since she got conned into being the staff photographer.
After all that, the camera shows the battery as fully charged!!
We're about to go on a 18 day trip to So. America and what I'm going to do is to take the camera with the used batteries still in it, and take a spare pair. I WAS figuring on having to take my charger with an adapter plug which would have been just one more thing to lug to Peru. Not now.
I just ordered some more for the future. I doubt if I'll ever use rechargables again.
Yes, these are expensive. In my humble opinion, the cost is WAY outweighed by the convenience..
Pay for themselves Feb 18, 2005
I gave some of these to a friend to try, and she and her son loved them:
"The set I used in my digital camera (while I don't have an exact hour time to provide you with), lasted much longer than the
rechargable ones I am using. I can't explain it because I
didn't think they would be that different. The rechargable
ones seem to go really quickly and then I have to keep an
extra set (or two) with me when I remember. The game boy ones have lasted longer as well per Matthew."
I think they are well worth the extra price since you don't need to buy batteries as often.
