They last a long time

I use these for some battery operated smart devices, like my doorbell and my smart lock. Usually the batteries drain quite quickly but these last about 10X as long, I found.

These batteries are one of a kind and last forever. We have them in stock at all times when needed. We use them in our smoke detectors to our gaming controllers. Won’t buy any other brand.

Energizer Ultimate Lithium AA batteries are lightweight and easy to handle, making them convenient for devices of all sizes. Their consistency is excellent, delivering reliable power across multiple devices without unexpected drops in performance. Discharge is slow and steady, so electronics last much longer compared to standard alkaline batteries. Disposal is simple, as they contain no mercury or heavy metals, though recycling is recommended when possible. Overall, they feel durable in hand, perform consistently, and maintain their charge impressively over time, making them a top choice for high-drain or essential devices.

These are some of the best batteries you can buy. They last forever. I have been buying them the last couple years to put in my battery powered window lights for Christmas. They last basically from thanksgiving to after Christmas when I take the lights down and still have power left in them.

In the hopes of having my battery operated Christmas lights last throughout the season, I purchased an 18 pak of the AA Energizer ultimate lithium batteries. I bought these from my local Sam's Club. My light strands were either fairy or micro led lights and required 3 AA batteries each. The number of led bulbs ranged from 18 (micro) to 30 (fairy lights). I used all 18 lithium batteries in 6 strands. These were all on timers (5-6 hours) and I wouldn't consider them as high drain. Much to my surprise, they only lasted a little over a week. The regular AA alkaline Energizer batteries at least lasted two or more weeks. How do you explain this? The packaging claims "%231 longest lasting batteries". I paid $34.99 for this pack of 18 batteries !!! That was $10.00 more than a 48 pack of regular AA Energizer alkaline batteries. This was a total waste of money and I definitely don't recommend! Not sure if this is typical or I just purchased a bad batch of batteries. I sent an email to Energizer customer support for their input.

I will NEVER EVER use another alkaLEAK, (too many ruined toys) i use Only recgargeables in high useage items, and i use these 20yr shelflife Lithiums in all low use , easily fogotten items like odd remotes and emergency flashlites, wall clocks, multimeters etc, etc. Note: try in item first, some electronics dont like the higher voltage when new about 1.8v

These batteries are perfect for your camera, MP3 player, etc. I also love them in my battery operated toothbrush. With regular batteries, I had to change them out every 2-3 weeks. These last 4 months before my toothbrush slows down. Wonderful! They're expensive, so I only use them in my cameras and toothbrush, and use cheaper ones for everything else.

The price increase to $32.98 from $21.98 (when I bought them last fall) seems highly excessive and Energizer (and Sams) ought to be ashamed of themselves for this 50% price increase. I am not in favor of rewarding companies for this kind of price hike.

I use a lot of AA Lithium Batteries every Fall and Winter on Trail Cameras. We're talking about 84 per year. Have researched it and this is the best price you will get anywhere. I ordered enough for all my cameras and got free shipping without having to drive 20 miles to the store to get them. Will do this every year.
