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.

Key fob battery, what else can I say? It replaced a dead battery.

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.

Amazon is a good source for batteries and good value too.

I installed these batteries expecting absolutely nothing—and that’s exactly what I got, in the best possible way. The device powered on immediately. No hesitation. No flickering. No moment of doubt where you wonder if the batteries are already halfway dead. Just instant, consistent performance. Days passed. Then weeks. The device kept working. No drop-off, no weird behavior, no unexpected failure. These are the kind of products you forget about entirely because they never give you a reason to think about them. They just sit there, quietly doing their job like professionals who don’t need recognition. If you’ve ever dealt with unreliable batteries, you know how valuable that is.
