Customer Ratings & Reviews

Because Lithium "primary" cells last longer than Alkalines, AND can deliver more current, AND have very long "shelf lives", I've switched to using them in my remote controls and Anything Else that uses Alkalines. Yes, they cost more than Alkalines, but I haven't had to worry about BATTERY LEAKAGE like I do with Alkalines and I have high confidence the Lithium-powered device will still work even if it's been "idle" for months at a time.

We have found these Ultimate Lithium AA batts last about 2x longer than the standard Energizer AA battery. We have the Yale Smart Lock 2 with wifi and fingerprint. This requires 4 of the AA batteries. The product docs say about 3 months for battery life, which is about what we got with Energizer regular alkaline AAs. Compare to the Ultimate Lithium AA that gave us about 6.5 months. Worth the price difference in this case!

These work great for wireless cameras; the last between 1-2 yrs depending on how often the camera is activated.

Great Batteries. Useful in Wifi door lock, keeps working in cold better than alkaline batteries.

Started using these on my Blink doorbell/cameras. Use them on everything now. Lasts longer than any other.

They work a long time you do get your use out of them if you use them correctly

I love these batteries they work perfect for my camera

Had a $10 coupon from Best buy these were also on sale couldn't pass it up very good batteries especially for cameras

Work great. I get them for my Blink cameras that for some reason don't use a rechargeable battery. Whatever.

Very helpful for outdoor and indoor cameras, not too expensive and get the job done.

The battery pack is the best value in comparison to the other stores and we get them delivered

Batteries are good just a little bit pricey for batteries.

**Nest Protect is calibrated for these specific batteries. They will last WAYYYYY longer (iirc like 6+ months instead of ~1 month)** I kept changing my batteries way too soon for my Nest Protect. Thought maybe it was because I bought cheaper Insignia batteries. Killed off the 20+ pack, then bought Duracell instead, but runtime was the same on those next 2 sets. I researched to find the Nest Protect specifically calls for this particular battery. (I mean a lot of products call for something specific, but it almost never matters) THEN I bought multiple packs from different sources on Amazon Prime. Looking closely, each pack was fake. Most of the time, the application of their battery wrap (protective logo sleeve on actual battery) was a pretty easy giveaway, and often the physical cell was a different shape. Just save yourself the headache and buy them from Best Buy. Yeah, these batteries are expensive for AA’s, but if you’re buying lithium batteries, they’re obviously for something worth that little premium.

I needed non-rechargable batteries for my doorbell camera. I didn't understand why they couldn't be rechargeable until I did some deep digging. Rechargeable batteries, evidently, don’t hold a charge well when cold weather sets in. These batteries have worked fine for my needs.

The best and required for Blink cameras. Lithiums are always more expensive, but they last long enough to make it worthwhile.

Didn't realize the type of battery and possibly the brand made a true difference in the working of a product. At first I had bought cheap, then read instructions which stated the required battery to function. It did matter.

I have had it with alkaline batteries leaking in my equipment. I am converting everything to these lithium batteries for that reason alone. They are expensive, but replacing equipment because of a leaking battery is a lot more expensive. Other than the high cost of these jewels, they also die suddenly without warning, unlike alkaline batteries that slowly deteroriate over time. But these batteries are the best I can find for my needs. They also have a very long shelf life, if you don't need to use them right away.

These are the best and o my batteries I use on my Cannon flash. They are a bit pricey these days but last for a full days if I am shooting in specific light conditions. I can’t finde them everywhere but Beat. It always has them in stock.

Definitely buy lithium batteries over alkaline. They last 3 times longer. I have tried different knock off brands from amazon but duracell last the longest by far.

This is a good product, nice battery life, I fully recommend
