Energizer Ultimate Lithium AA Batteries
Amazing product... except for the price.
Bought both AA and AAA Ultimate Lithium batteries from Energizer - my first purchase from this manufacturer, ever. I really have to tell you: these batteries are absolutely extraordinary! Extremely long shelve life (mine - made in Singapore - will expire around 2026 (!!!) - if I'm still alive - otherwise these batteries will outlive me!), absurdly light weight (in fact, these are the lightest AA and AAA batteries I've ever seen), very good-looking (love the chrome 'n' blue graphic design style) and very stable (thermally and mechanically). The only thing that makes me sad, is for the fact that not all torches/flashlights out there are 'lithium battery compatible'. Indeed, my also extraordinary Fenix LD01 flashlight, states that 'lithium batteries are not recommended' and that I should stick to alkaline or rechargeable batteries which are FAR heavier than the Ultimate Lithium (buy one of each, weight them on your hands and you'll see what I mean...) - and I really regret this, since these batteries are so much lighter and long-lasting than any alkaline/rechargeable combo out there. Perfect for EDC or critical/survival gear - if these can accept lithium batteries, that is. On the other hand, price is steep and one should think through before buying, but for survival gear you really don't want to compromise your life on it. The absolutely best batteries from Energizer, in my opinion, and the brand's best technical achievement so far. Well done, Energizer. Well done.

didnt last more than a three uses
I bought pack of 8 for my 3 and 6yr olds LeapPad and they have been charged a total of 2 times and 4 out of the 8 are no longer usable. This is the second set I bought I thought well maybe it was just the my imagination they lasted longer than what they seemed to but I don't think so considering these didn't last long either. Will not buy again and wouldn't recommend.

I honestly had no idea what batteries I was using in my digital camera. I make a lot of videos on trips and stuff like that ranging between 10-20 minutes long. My battery is just now starting to die and I opened it up and found out that it was these Ultimate Lithium batteries. Just perfect! I think I've had these batteries in my camera since August and they're just now dying. 6 months of not having to change my camera batteries is simply amazing. Definitely recommend!

Do not last long at all
I have bought 8 of them now, not one of them lasted in a xbox controller for more than 5 days, of heavy use. Regular duracells seem to last as long and are a lot cheaper. The Energizer rechargeable on the other hand is a battery that lasts long with heavy use and is not to expensive. Only problem with them is they are a tad bit larger than a normal aa battery and can fit to tight.

Overall great, but has a fatal flaw
I ran a science fair experiment with these and they came within 20 minutes of being the best, however, 10 hours in, one battery died and the other was still going, it quickly died afterwards.
before that, it kept max. charge and performed amazingly well in the toothbrushes I used. I do recommend this but my experiment had shown that 1. It is not the best battery and it was outperformed by the Duracell Ultra Powers.

Use these batteries exclusively
I purchased a new Nikon digital camera for $300.00 in May and I had purchased a high priced energizer battery and the camera did not work took it back to the store thinking it was the camera, the store associate tried the batteries in another Nikon camera same model same results. I decided to bite the bullet and purchase the Energizer Utimate Lithium batteries and viola. Works wonderfully. I just recently placed new batteries in the camera as they were running low. I also recently purchased The Energizer Instant Charger made specifically for Ipod & Iphome and this came with the Energizer Ultimate Lithium Batteries and works fantastic am very pleased so much so I purchased 3 more more stocking stuffers for the kids for Christmas, $24.00 is well worth it portable to carry in your purse or briefcase.

Very poor when compared to Max product
We did a head to head comparison for a school project. Alkaline v Lithium, Energizer Ultimate v Energizer Max. To our surprise, the Max outlasted the Ultimate by 12 minutes!
