Energizer Ultimate Lithium AA Batteries (2 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 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.

Great batteries. Lasts a long time. Great fit, perfect size. Good value and great connection.

I immediately bought these batteries for my Blink doorbell and Blink cameras. They work wonderfully, and the longevity is impressive. They can last over a year or more, which is great value for money. The durability is also excellent. I highly recommend these batteries; they last much longer than regular batteries. I had them in my doorbell and cameras, and if your camera is super sensitive and picks up a lot of noise, your battery may not last as long. However, I still recommend buying these batteries.

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 Ultimate Lithium AA Batteries (4 Pack), 1.5V Lithium Double A Batteries I run these in my Blink cameras, and they’ve been great. I’m getting about a year of active use out of a set, which saves a lot of time not having to constantly swap batteries. They hold up well in all weather conditions—heat, cold, doesn’t seem to matter. That’s a big deal for outdoor cameras where reliability matters. If you’re tired of chasing battery changes all the time, these are definitely worth it. Set It and Forget It Power.

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.

Works great in Blink doorbell
