Energizer Ultimate Lithium AA Size Batteries - 20 Pack (5-4packs)

The batteries in my smoke and carbon monoxide detectors finally died, and these were a great replacement option. Nice to have my detectors back up and running.

Good

Work great so far!

These batteries do great in any devices using lithium, batteries, including my Blink outdoor cameras. Last longer than others I’ve tried.

I’ve always trusted Energizer for my battery needs, and their lithium batteries certainly get the job done. They last a decent amount of time and perform well in high-drain devices like cameras and flashlights. The biggest plus? They’re much lighter than traditional alkaline batteries, which is great for portability, especially in gadgets that you need to carry around.That said, they’re not necessarily mind-blowing. I’ve found that while they last longer than standard batteries, they don’t necessarily outshine other lithium options on the market, especially when you factor in the price. Sure, they work well, but they’re also a little more expensive, and I’ve had comparable performance with other brands.Overall, they’re reliable and efficient, but I wouldn't say they offer anything that makes them stand out from the crowd. If you’re already a fan of Energizer, you’ll like these. If not, you might want to shop around for a better deal.

Lithium batteries are great, never leak and last a long time. Also good for outside devices that see freezing weather. The ones in my weather station and Blink cameras last for years.

While these batteries are great in general, they are great batteries to have as backups, due to the extended shelf life.
