Let's talk about these LiCB A23 batteries. I've been using them in my garage door opener and doorbell for months, and here's the real tea.
The good? These little guys deliver solid 12V power right out the package. My garage door opener that was struggling with weak signals suddenly worked like new again - no more awkwardly standing in the driveway pressing the button repeatedly!
Price-wise, this 5-pack is a steal compared to buying singles at local stores. I paid nearly double for just two batteries at Walmart last year. The blister packaging keeps them fresh too - no corrosion issues so far.
Now the not-so-good: One pack I ordered last year had a dud battery that was completely dead on arrival. Quality control might be hit-or-miss. Also, while most worked great in low-drain devices like remotes, I wouldn't trust them for anything high-drain.
Pro tip: These are perfect for ceiling fan remotes, doorbells, and key fobs where you need reliable but not constant power. The 3-year shelf life means your extras won't go bad waiting to be used.
Final verdict? For the price and convenience (hello Prime shipping!), they're worth it despite occasional quality issues. Just don't expect miracles from budget alkaline batteries.
