Holds power in storage for up to 20 years for trustworthy backup energy
Style:AA-8 New Energizer Ultimate Lithium batteries raise the bar on long-lasting power for today’s modern electronics. Earning the title “the world’s longest-lasting AA batteries in high-tech devices”, Ultimate Lithium helps ensure uninterrupted gaming, music, home safety systems and critical work tasks. With its ability to perform in extreme temperatures and last in storage for up to 20 years, Ultimate Lithium is the clear choice to dependably power the essential devices in your life.
Check shelf life dates. Several packages had 2026 dates meaning they had been on the self for 10 years already. We will use these first and keep the others with 2033 dates next. I had hoped to get new fresh batteries that would mean they would have 2036 dates. Still the best batteries for cold weather.
I’ve become a fan of lithium batteries like these for most uses. The main exceptions: their slightly higher voltage (about 1.8V new) can burn out LED flashlights intended for use with alkaline batteries (about 1.5V new); and devices where rechargeable batteries work well, such as portable shavers, beard trimmers, and the like.But for everything else: remote controls, clocks, incandescent flashlights, portable electronics, etc., they do just what they say: they last longer and shave off a bit of weight.
Bought to replace cheap Dollar store batteries in a Digital thermometer. The dollar store batteries at 25 cents each lasted 1 year before dying. These $8 batteries died after 1 year and 2 months. NOT worth the extra $7.75. Could have been a bad batch, but the company who sold them refused to exchange them, so who knows.
The Energizer Ultimate Lithium labeling states that the battery will last up to 9x longer. Compared to what I’m not sure. In my experience they do last significantly longer than alkaline, but perhaps two to as much as four times longer. Even with the longer life the Lithium batteries are more expensive to use, in my experience, than standard alkaline batteries. However, in certain applications the additional battery life and lighter weight of the Lithium batteries are well worth it.I buy the lithium batteries primarily for two uses: headlamps (I use AAA in this application) and GPS on extended backpacking and canoeing trips. The longer battery life means you simply have to carry less; and in particular on backpacking trips the lighter weight of these batteries is a very positive feature. In a hand-held GPS (I use a Garmin eTrex HcX) the Lithium batteries will provide perhaps 25 - 30 hours of operating time. So, on a 10 day trip I would probably bring (in addition to a fresh set of batteries in the GPS) four extra AA lithium batteries for the GPS. If I were using alkaline batteries I’d have to carry perhaps 10 to 16 extra AA batteries. This is a big difference in weight and a lot more hassle changing batteries.Bottom line, the Lithium batteries are lighter than alkaline and last significantly longer; they are also more expensive per hour use.
The gold standard for primary (non-rechargeable) lithium batteries. I use them in emergency flashlights that I keep in my cars, because they have a shelf life of many years, don’t leak, and work in sub-zero temperatures. With these batteries in my emergency flashlights, I’m very confident that they will work when I need them. However, these batteries are too expensive for frequently-used devices, for which rechargeable NiMH batteries like Eneloops are more suitable.
Out of the four batteries in the package, one of them did not work. How long does this stuff sit in a warehouse? Thankfully, my friend had an extra battery for me to borrow in order for me to take pix with my camera that requires these expensive batteries. Very unhappy customer here!
There are no better batteries – period, especially for instruments which require peak voltage throughout the battey life. Lithium batteries give it up fast in the end, but they hold their peak almost to that end, dropping voltage when 95% plus of the available charge is exhausted. For my uses, image stabilizing binoculars, digital microscopes, and similar applications, you cannot do better with today’s limited, self-contained technology than lithium encased (non-rechargeable batteries) – the Energizer brand name in particular tops them all. After trying the lot, it seems the old ‘Bunny’ does the job better… ***** star *****
These lithium AA cells (“batteries”) are absolutely fantastic. They weigh less than standard alkaline cells, they work in sub-zero temperatures and last a good 5 times longer than alkaline cells. The discharge curve is quite flat (that is, the cells work right up to the end, then quickly drop off rather than “slowly fading away” like alkaline cells do). These lithium cells also have a long shelf life. I once found a lost, unopened pack of four AA cells that was at least 5 to 8 years old. At first, I was surprised that they didn’t leak like “old batteries” do. Not only that, but these old cells still had a full charge and lasted as long as brand new ones do. I’m hooked on these lithium cells. I never buy alkaline cells anymore.
These met my expectations. Great for extreme temperature applications.
Great, long lasting batteries. These batteries are wonderful! We use them for an outdoor weather station gauge and they have lasted for well over a year.
Seems as though these batteries were nearly dead when I received them…
If you have outdoor thermometers these batteries are a MUST have. Cold weather kills alkaline batteries super quick.
My Canon SLR never worked well with the battery grip, until I put Ultimate Lithium Batteries in it. If I had found these batteries years ago I would have many more prize photos.
Great battery. Long lasting.
I got these and used them right away. Very good batteries! I don’t buy anything else but lithiums from energizer. Highly recommend!
I need long-lasting batteries to be used outdoors in cold Iowa winters. The previous set worked superbly for about a year, so I bought some more.
Found my NiCd batteries wouldn’t handle the cold during winter in NC in my hunting trail camera. Threw these in at the end of the year and continued getting pictures from the…
