EnergizerUltimate Lithium AA Batteries, World's Longest Lasting Battery for High-Tech Devices (4 Each), Black (EVEL91BP4)

These are definitely great for certain electronics where you need the lithium battery over rechargeable or alkaline. I use these in my wireless thermostat for my AC and it’s great. Before I was going through alkaline batteries like once a month and rechargeable just didn’t work. These last easily 6+ months

Just what I needed for my Blink video doorbell. Funny thing is I didn't know that the old Energizer E2 Lithium batteries had changed names to the Ultimate Lithium, so it took me awhile to realize why I couldn't find the E2 ones anymore. These are the best batteries for various weather conditions that these video doorbells have to deal with.

Work great!

Great for outdoor cameras or indoor

I use these in my remote control units they last a long time. Great priceQuality:

They work good in the cold. Don't last as long as I hoped.

Love these batteries. They last a long time these batteries have a long shelf life

I was being thrifty and decided to use alkaline batteries in my doorbell. Well that was a big mistake because it zapped the power in no time. Once i put these bad boys in it worked as intended. The brand is trusted and has indeed “kept going,and going,and going” amazon had them slightly cheaper than the retail stores. They fit nicely in the battery compartments and felt more weighty than the alkaline. They are not rechargeable in which i already have loads of those.
