CR2 Lithium Batteries (2 Pack), 3V Photo Battery, CR2 3V Battery | For garage door openers, keyless entry, cameras, and security devices; 12V 23A battery

These batteries worked exactly as expected and have held their charge well. I used them in a small device that requires A23 batteries, and they were easy to install and started working right away. I appreciate having a trusted brand for specialty batteries since they can sometimes be harder to find locally. So far, they've provided consistent performance without any issues. Overall, these are reliable, long-lasting batteries that get the job done.

Energizer A23 Batteries are exactly what you'd expect from a trusted brand — reliable, long-lasting, and consistently performing when you need them most. These small alkaline batteries are used in a variety of devices such as garage door openers, key fobs, doorbells, and small remote controls, and the Energizer A23s have worked flawlessly in every application I've used them for. The battery life is genuinely impressive for such a compact size. They've lasted considerably longer than generic or off-brand A23 batteries I've tried in the past. Once installed, I essentially forget about them — which is exactly the kind of reliability you want from a battery you don't think about until it dies. The 2-count pack is practical for most household needs. They arrive well-packaged and ready to use right out of the box. While the per-unit cost is slightly higher than no-name alternatives, the extended performance and peace of mind from using an Energizer product more than justifies the price. Energizer has built its reputation on quality and dependability across all battery types, and the A23 is no exception. Whether you're replacing a battery in a remote or a security sensor, these deliver consistent voltage and performance throughout their lifespan without the premature power drops you sometimes get with cheaper options. A straightforward, dependable product that does exactly what it's supposed to do. Will continue purchasing Energizer for all my specialty battery needs.

NEEDED THESE FOR GARAGE DOOR OPENER, AND HAVE BOUGHT MANY TIMES BEFORE.

These batteries can be hard to find so thankfully they have them on Amazon. I’ve had them for quite some time and they seem to last making them a good value for the money.

I picked up these Energizer A23 batteries for a few small gadgets, and overall I’m really impressed. Battery life has been solid — they’ve lasted through regular use in my remote, key fob, and a couple of other accessories without dying quickly, which is exactly what you want from small alkaline batteries. They’re easy to use right out of the package. The size is exactly what my devices call for, and they slide into slots without any struggle. Speaking of installation, that’s another plus — they just click into place with no fuss or awkward tugging. The look is classic Energizer: clean, professional branding that actually makes the batteries easy to identify in a drawer full of different types. Nothing flashy, but they look trustworthy and well-made. Longevity has been good so far in my experience. I haven’t had any fail early, and even in devices that sit unused for a while they still hold their charge well. I’ve always had good luck with Energizer, and these are no exception. Compatibility is spot on — they fit all the devices I bought them for (keyless entry remotes, mini LED lights, etc.) without any weird fit issues. If your gadget calls for A23, these plug right in and work every time. In short, reliable battery life, easy installation and use, solid look and build quality, and good compatibility with all my A23 devices. Totally worth it if you need dependable small batteries.

One of the 12-volt A23 batteries needed replacing in Annie's great doggie door bells that we got on Amazon three years ago [https://www.amazon.com/dp/B0B9X47GDH]. We have door bell on each side of the door. Two Energizers in a package with a 2-year shelf life expiration date are perfect. The batteries don't need replacing very often, so with these I will have the extra one on hand already for when the other one needs replacing.

Classic Engergizer batteries that work well and seem to last long.
