[This review was collected as part of a promotion.] The Energizer 123 Lithium Batteries are a must in my household. Its so important to have them around to replace batteries on my smoke and carbon monoxide detectors. My alarm recently went off (turns out the batteries needed replacing) and I don’t want to be caught off guard again! The batteries are powerful and keep my devices working for a long time. The packaging is great and makes it easy to store until needed.

[This review was collected as part of a promotion.] These energizer CR123 lithium batteries have an excellent in my SureFire 6PX Pro. They deliver consistent 3V power with strong output and reliable performance, especially when using the higher brightness settings. The flashlight feels just as bright and responsive as it should with no flickering or weak output. Battery life has also been solid and they seem to hold their charge well in storage compared to cheaper alternatives. I trust these for both everyday use and emergency situations because they've been dependable every time I've needed them. Definitely a great choice for high performance flashlights.

[This review was collected as part of a promotion.] I didn’t realize how much battery performance mattered until my smart door lock started chewing through them. I was swapping batteries way more often than I should’ve been, which is not exactly ideal when you’re relying on a smart lock for every day security. Switching to Energizer 123 lithium 3V batteries made a noticeable difference almost immediately. They last significantly longer, and I’m not constantly worrying about whether my lock is going to lose power at the worst possible moment. That peace of mind is huge. These batteries have been incredibly consistent, holding power well and performing exactly how I need them to. If you’re tired of constantly replacing batteries in your smart locks these are absolutely worth it. They’ve made my setup feel way more dependable and that’s exactly what you want from anything tied to your home security.

[This review was collected as part of a promotion.] These batteries are known for long shelf life and that definitely shows they’re reliable, even if you don’t use them right away. they are compact, but powerful for things like flashlight camera security systems. The only downside is they’re more expensive than other batteries. but you do get what you pay for.

This DOES NOT replace the CR123a batteries. The bottom of the packaging state it is a replacement for the CR123a.

these are CR2 Batteries. i ordered 123 batteries. i have no use for these.
