I can't comment on the battery life yet, but will when my ADT Security key fobs die again. The Duracells lasted 6 months before having limited range, and then another 2 months before croaking altogether. The thing that suprised me was that they both died at the same time, in spite of one getting used much more than the other.
Wish there was a longer life equivalent, such as a lithium, but I have been unable to find one.
Edit;
Just hit 10 months and the key fobs are still going strong. Looks like battery life is much better than the Duracell!
For those who have thanked me in comments, You're very welcome!!! Energizer A23 Battery, 12 Volt - 2 Pack
I originally went looking at local stores for the A23 Lithium batteries and found them much more expensive. I found these cheapest at Amazon & they work great for my garage door openers. I just wish there was a rechargeable version & recharger.
I bought these batteries for the button cells inside. Those normally sell for $3-5 a piece. And inside each of these 12Vs are 8 button cell batteries (watch batteries).
So do the math.
Average button cell price: $4.00
Number of button cells inside: 16 (total)
Total savings: $64.00 - $3.15 = $60.85
Good product. Thanks
My garage remote opener battery died about a week ago, so I decided to go to the local megastore to get a new one. I didn't bother checking the details of my battery's characteristics, assuming that a "short skinny battery" would be all I needed to remember. I found a couple of batteries that more or less looked like my garage door's battery so I bought them, only to discover that they were the wrong kind. I went back to the store, this time bringing my battery with me, only to discover that they did not carry this particular kind. That's when I decided to look for it on Amazon. I found the exact battery that I used thus far - Duracell A21/23, but then I also came across these Energizer A23s. They were somewhat cheaper, but I was not sure if A23 is exactly the same as A21/23. The batteries were pretty cheap though, so I decided to give it a try. I am happy to report that they fit into my remote opener perfectly and they worked without a hitch from the get go. I am so glad that I don't have to call home from my cell phone while driving any more, asking my wife to open the garage door for me!
I liked the fact that there were no shipping charges for these batteries. They seem to last for at least four to five years with my level of usage, but I decided to get an extra pair just in case. In case that they run out of power uncharacteristically early, I will write an update to this review.
I bought this on this site as they used to be hard to find in stores. After waiting ages for them to arrive i found them in the local supermarket for $2.99, so they are now vastly overpriced here. And have gone down here $2 since i ordered them earlier this month. Annoying! - Energizer - Remote Control Batteries - Energizer A23'
