Perfect for Optics
These Energizer A23 batteries are excellent. I use them in my optics, and they deliver consistent, reliable power every time. They last longer than cheaper alternatives, and I’ve never had issues with performance. The packaging is secure, and the batteries are fresh when they arrive. If you need dependable A23 batteries for scopes, sights, or other devices, these are a solid choice. Worth the price for the peace of mind and quality.

Classic and can’t go wrong
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 battery for my gate opener and one battery for a spare!
I ordered these for my gate opener, because I found that they tend to last longer than the other brands. Energizer is a brand name that you can trust. I've never had one corrode inside a device. Battery life is excellent and they're a great value. And Energizer carries just about every size battery you could want or need!

Exactly What I Needed for a Small Mod – Good Value
These are funny little batteries, but they were exactly what I needed for a 24v modification for my bass guitar where A23s were required. They dropped right in, worked immediately, and have been holding their charge well so far. The biggest win for me is the price — these were about 50% cheaper than buying locally at Walmart, which is great considering they’re name-brand alkaline batteries. No leaks, no issues, and they do exactly what they’re supposed to do. If you need A23 batteries for remotes, electronics, or small mods, these are a solid, affordable option.

Small batteries with big reliability
These Energizer A23 batteries do exactly what they’re supposed to do, and they do it well. I’ve used cheaper off brand versions before, and they never last, but these Energizers have been consistent and dependable every time. Perfect power output, no random failures, and they hold their charge like champs. For small devices, remotes, or anything that needs an A23, these are the ones worth buying. No surprises, no headaches just reliable batteries that actually last.

Great key fob battery
Its a battery, what can I say. Key fob died, its battery was 5 years old so I ordered this package. It's a great price and fob works again.
