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

Great product at a great price

They arrived on time and in good condition.

These are the only batteries that seem to last in my Blink cameras. Regular batteries die within a week. Other lithium batteries die within 30 days. These last me (depending on camera usage) between 47 days and 98 days (I keep an Excel spreadsheet so I know if I need to switch em out).

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.

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.

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

Ordered these up to replace the batteries in all my Blink cameras, and they’ve been great. They’re lithium which Blink cameras say they need.The 20-pack is a solid value, so I could replace all the camera batteries at once. They work exactly as advertised and hold up well in the cold, which is a bonus since my cameras are outside (obviously)If you need reliable, long-lasting batteries, these are definitely worth grabbing. Now if only they could power my energy levels!

Great batteries but too costly.
