Customer in Napa: I have a wireless alarm system that needed battery replacement in the high activation area sensors after 3 months or so. These batteries tested at full 12V, fit perfect and were at an excellent price point. If you need more than just a few A23's, this 50 pack is an awesome value.
Follow up - It is three months since I replaced all sensor batteries with the ones from this 50 pack. Today I had two sensors throw low battery warnings, so it looks like I am getting the same life from these replacements, as I did from the original cells. Performance is about what I expected, and I am still happy with the purchase..

Amazon Customer: I purchased these In November, 2017, and installed them in 27 wireless sensors for my home alarm system on New Year's Day 2018.
Fast forward to today, in September 2018 - these batteries are still working just fine! The only exception has been a sensor for the front screen door, which is opened and closed many times each day, causing the sensor light to light up each time. I had to replace that one battery today, prompting me to write this review. So far, the life of these batteries in my sensors is 9 months, and based upon their performance so far I would not be surprised if they even get to a year.
I have had this alarm system for 3 years, and previously bought the cheaper batteries that are offered on Amazon. Those lasted anywhere from 3 to 6 months at most, depending on the brand.
Changing batteries is always a bit of a hassle for everyone, but having to change frequently 27 batteries in my alarm system sensors every few months is over the top. That is what I was doing regularly before I bought these batteries. I definitely recommend these Duracell batteries over any other 23A battieres listed on Amazon.
Once you calculate the higher price and low...
