    4.0 out of 5 stars Shelf life of the batteries
    Reviewed in Canada on February 7, 2022
    Verified Purchase
    Ordered two packs of these batteries as I believed that being in original energizer packaging might give me a reasonable expiry date. No such luck on 8-10 years. Got them feb7/22 and expiry date is march/23. So will unlikely get full use of them.Obviously the supplying company is supplying near expired batteries at a discount. (Am presuming they’re cheaper). Also being near expiry date they may not last nearly as long. I really think this is fraudulent selling as one does normally expect about 10 years of shelf life. I would not buy batteries again through 鶹. The presumed lower price is not worth getting only 10% of normal expected shelf life. Just tried to use the batteries and none worked . They are 12 V batteries and all tested between 7-9 V, way too low. Supplier was “My battery supplies” via amazon. Don’t waste time with their batteries. I sent them back for refund.

    5.0 out of 5 stars Reliable Power in a Small Package—Perfect for Small Electronics
    Reviewed in the United States on August 17, 2024
    Verified Purchase
    **Energizer Miniature Alkaline Watch/Electronic Battery A23bp-2, 2-Count**

    **Reliable Power in a Small Package—Perfect for Small Electronics**

    I recently purchased the Energizer Miniature Alkaline Watch/Electronic Battery A23bp-2, 2-Count, for use in a couple of small devices around the house, and they’ve performed exactly as expected. Energizer is a brand I trust for reliable batteries, and these have not disappointed.

    **What I Liked:**
    - **Dependable Power**: These batteries deliver consistent power, which is crucial for small electronic devices like remote controls, key fobs, and other gadgets. They’ve provided reliable performance from the moment I installed them, keeping my devices running smoothly without any issues.
    - **Long-Lasting**: One of the standout features of Energizer batteries is their longevity. These A23 batteries have been going strong since I installed them, and I haven’t noticed any drop in performance. This is especially important for devices that are used frequently, as it reduces the need for constant replacements.
    - **Perfect for a Variety of Devices**: These batteries are versatile and can be used in a range of small electronics. I’ve used them in a garage door opener and a keyless entry remote, and they’ve worked perfectly in both. The size and power are ideal for these types of devices.
    - **Convenient Packaging**: The 2-count pack is convenient and ensures I have a spare battery on hand when needed. The packaging is easy to open, and the batteries are clearly marked, so there’s no confusion when it comes to installation.
    - **Trusted Brand**: Energizer is a brand I’ve relied on for years, and their products consistently deliver quality and reliability. These batteries are no exception, and I’m confident in their ability to keep my devices powered for a long time.

    **What I Didn’t Like:**
    - **A Bit Pricey for the Size**: While the quality is excellent, these batteries are slightly more expensive than some other brands. However, considering the reliability and longevity they offer, I believe they’re worth the extra cost. Still, if you’re looking for a budget option, you might find cheaper alternatives, though they may not last as long.
    - **Limited Use**: These A23 batteries are specialized for small electronics, so their use is somewhat limited compared to more common battery sizes like AA or AAA. If you don’t have many devices that require this specific battery type, you might not need them often. However, for those specific devices, they’re a must-have.
    - **Not Rechargeable**: Like most miniature batteries, these are not rechargeable, which means they’ll need to be replaced once they run out of power. It’s important to dispose of them properly and have replacements ready when needed.

    **Bottom Line:**
    The Energizer Miniature Alkaline Watch/Electronic Battery A23bp-2, 2-Count, is a reliable and long-lasting power source for a variety of small electronic devices. While they’re a bit more expensive than some alternatives, their dependable performance and the trusted Energizer brand make them a worthwhile investment. If you need a battery that you can count on for your remote controls, key fobs, or other small gadgets, these are an excellent choice. I’m very satisfied with their performance and would recommend them to anyone looking for high-quality, reliable batteries for their small electronics.
