Product Description

All of Energizer e2 Lithium batteries' advantages combine to make them the World's Best AA batteries in high tech devices. First, they are the longest lasting AA batteries in high-tech devices, bar none. Second, both the Energizer e2 Lithium AA are 33 percent lighter than their alkaline counterparts. The increased portability afforded the user make them ideal for travel and situations where every ounce counts. Third, Energizer e2 Lithium batteries perform well in extreme temperatures, allowing digital cameras, flashes, CD players or MP3 players to work from the Arctic to the Sahara. Lastly, Energizer e2 Lithium batteries have a shelf life of up to 15 years vs. 7 years with ordinary alkaline, guaranteeing that they will perform when needed.

Product Details

• Brand: Energizer
• Model: L91
• Number of items: 1
• Dimensions: .80" h x 3.80" w x 4.50" l, .20 pounds

Features

• Power lasts up to 7-times longer than similar alkaline battery
• Battery chemistry and construction differ in the two systems. Energizer e2 Lithium batteries are built in a spirally wound construction. This design helps the battery meet the high current drains of many of today's devices
• Since lithium is a very active material, it provides a great deal of power relative to the amount of material used. Lithium is not considered a heavy metal
• When powering a device, you should only use a lithium battery with other lithium batteries - not compatible for use alongside an alkaline
• This battery is not rechargeable

Amazon.com Product Description
The Energizer AA lithium battery lasts five times as long as alkaline batteries in digital cameras, three times as long as batteries in other cameras and flash applications, and weighs less than typical AA batteries. It performs in extreme temperatures, from -40 degrees to 140 degrees F. Pack of four.

Customer Reviews

Depends on the application.
I love these batteries!

Something to consider tho, is that a Warehouse Club 48-pack of regular 2800ma alkalines are about the same price. So for low-current applications where maximum life, cold weather performance, weight, etc. isn't critical, there are much more cost-effective choices.

AND speaking of critical, I had a little digital safe at the office (for postage stamps, the checkbook, spare car keys, and such) that ran on AA's. I used it for years on regular alkalines and replaced them every 3 months or so. When the alkalines got low, it would still weakly open 5 or 10 times to give me plenty of time to change them. When I switched to a set of these lithiums (to reduce how often I had to do the replacement procedure) they lasted just over twice as long, BUT when they died, they were totally gone-ola. I think they're way better at putting out full voltage to the end - which is ordinarily what you want out of a battery, unless you lock the manual-opening keys in the safe itself!

Good
The best battery that you can ever find!if you simply calculate,you wil understand that it's cheaper than Alkaline!

The Absolute Best Non-Rechargable Batteries
If you are going to a foreign country and need long lasting (but non-rechargable) batteries for your digital camera (assuming it uses standard batteries), get a few packs of lithium batteries from Amazon. Yes, they are somewhat more expensive but they will last MUCH MUCH longer than any comparable non-rechargable battery. Remember, if you use rechargable batteries overseas you will need a compatible plug-in charger for the country you are in. That can be a real hassle. Lithium batteries also have unbelievably long storage times...many many years!
