Ultimate Lithium AA Batteries (4 Pack), 1.5V Lithium Double A Batteries

We use these Energizer Ultimate Lithium AA batteries in our Kwikset Halo deadbolts, and the battery life has been amazing. With regular generic alkaline batteries, we were replacing them every couple of months. After switching to these, they are still showing 100% battery life after 3 months of use. They definitely work better than generic batteries, especially in high-drain devices. If you have something that goes through batteries quickly, these are absolutely worth trying. Yes, they cost more upfront, but the longevity more than makes up for it. Highly recommend.

These lithium AA batteries are excellent. They last much longer than regular alkaline batteries and provide consistent power, even in high-drain devices. I’ve used them in cameras, remotes, and kids’ toys with great results. They also hold their charge well when stored. Great quality for the price and very reliable — I’ll definitely keep buying these.

These Energizer Ultimate Lithium AA batteries are incredibly dependable, especially for devices that need consistent, long‑term power. They last noticeably longer than standard alkaline batteries, and they hold up beautifully in cold weather — perfect for flashlights, outdoor gear, cameras, and anything you don’t want dying at the wrong moment. They’re lightweight, leak‑resistant, and maintain strong performance even after long storage. If you rely on battery‑powered devices or just want something you don’t have to replace constantly, these are absolutely worth it. If you want power you can trust, these are some of the best AA batteries you can buy.

These ultimate lithium double a batteries from Energizer are probably the best I have ever used especially for using in cameras that provide security around my home they last really long on inside cameras without the stress of weather. I especially like the fact that Energizer advertises that they could possibly last up to 25 years in storage if needed before use.

These are an exact replacement for original equipment batteries in Blink doorbell cameras. Like the batteries that come packaged with the Blink doorbell, these don't last very long, ~3 months in a wired doorbell.

Energizer, always the best! Never leaks, and lasts the longest!

Got these batteries for my blink doorbell camera. They work well at cold temperatures. Easy to install just like any battery. We live in a neighborhood with kids so the camera stays busy. The batteries lasted a sufficient amount of time as expected with the business of the camera. Bought on Amazon as the value was better than local stores. Will buy again when needed.

Long lasting use in our wireless cameras pricey though
