Energizer 123 Lithium Batteries (2 Pack), 3V Photo Batteries

I have used engerizer lithium batteries for many years ... from trail cameras to remote controls and other areas when replacing alkaline requires replacing too often, corrosion, and more in the landfill. These batteries last longer and perform very well and are a perfect fit. They pop right in and don't leak or corrode like alkaline. This particular size is in smoke and carbon monoxide detectors that are wireless for me. They last more than a year in that application. Since this is an odd size there aren't many options and lithium has increased in price a lot in recent years.

Fantastic batteries! The lithium type lasts forever so well worth the extra cost. My front door lock is still at 100% 2 months after changing to these batteries.

I purchased these batteries for my home fire alarm and CO₂ detector, which I replace about once every five years. The battery life is long-lasting and offers better value for the money compared to store prices. They are easy to install, but it’s important to check the size and length of the battery before purchasing to ensure compatibility. Overall, I’m happy with buying these batteries online and would definitely recommend them for devices that require reliable, long-term power.

He just keeps going and going and going.... You know how the story goes but yeah, excellent batteries at a great price, I was happy with the performance of my weapons mounted light with my old borrowed battery, but when I tossed one of these bad boys in there the light output was definitely better. Never underestimate the Energizer bunny!!!!

Batteries are batteries…

Haven’t had any issues with the batteries. They fit my security door sensor and popped right in. these were a little cheaper than purchasing from my local home improvement store.

Battery works as it should. Often easier to shop Amazon for odd sized batteries. Use in Simplisafe equipment.

Good price good quality

Came early, worked perfect. Thank you.

Quite why such confusing name, no idea, but they are CR123A in my book, 3V lithium 10year life, that fits in my CR123A devices. Originally designed for digital cameras, now popular in alarm and security devices. Mine are used in motion detectors. Couple of reviews have commented on poor dates, robbing them of battery life, and voltage. Mine are dated with 9 years and 11 months left, so happy there, voltage looks good at 3.27V, my devices have powered up ok. But you will have to wait for longevity feedback, I'll comeback and update after "hopefully a year or so", if I'm back sooner, then probably bad news. But very hopeful at the moment.

Beste Qualität! Wurden mir selbst von einem Fachmann empfohlen, wurde nicht enttäuscht. Sehr langlebige Batterien!

Je ne sais pas pourquoi vous indiquez que le colis est perdu car je l'ai bien reçu en temps et en heure.

So expensive everywhere else but perfect price here
