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.

If you like an extremely long life for batteries this is it. That said, I'll compare. I use these AA Energizer Lithium batteries in my wireless Xbox 360 controller. Typical life in controller with regular alkaline batteries is 2 weeks, or 3 tops. With the Lithium, it lasts about 2.5-3 months. These batteries rock. And they have incredible shelf life. I bought a 12 pack of them about 3 yrs ago and they expire on 3/2027

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.

These Energizer batteries are excellent for cameras and other outdoor electronics. Works very well in cold conditions so you don't have to worry about cold nights running the batteries down. They are not any smaller or bigger than other batteries so no issues with fitment.

I used these lithium batteries in my trail cameras that require 12 of them. With alkaline batteries, I normally get 5000 - 6000 images before they die. These lithium batteries failed between 2000 - 3000 images. When they failed I tested them. The problem was consistent. 2 - 4 of the batteries registered 0.0 volts while the remaining batteries were in the 1.4 - 1.6 volt range. Failures were distributed across 2 manufacturing lot numbers. I will never purchase them again. A friend used a different brand lithium battery and had similar issue.

Could not find these batteries with the other batteries. Found the AAA versions but not the AA version. Asked a number of Sam's Associates but they were no help. I told one associate the store inventory showed them in the store but was told inventories were delayed by as much as three days. So I ordered these batteries for curbside pickup the next day. Second day I made a trip to curbside pickup and got the batteries.

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.

Bought a second pack while on sale. I love the life of the batteries in my CD player and radio. I will not use anything else in my electronics but this brand of batteries. I wish that Sam's Club would carry the AAA version of these batteries in the value pack size like this.

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

I use these for my outside cameras. Overall they work great but they don't last long with recording. I'd say I have to change the batteries roughly every 1-2 months. If I leave my cameras on consistent record they last about 2 weeks- so battery life could be better, but for the price point they're not bad.
