Not much to say about this battery yet, except that it restored my ADT Security key fobs to life. If your device uses any of the following batteries, this is what you are looking for;

Duracell: MN21
VARTA: V23GA
EVEREADY: A23
NEDA: 1811A

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!!!

I thought I was going to get the exact blister pack that was pictured but it wasn't, instead I got the retail single blister packs where the batteries are made in China. Both work but the twin blister packs are made in the USA and lasts at least 50% longer, next time I'll ask the seller if they are selling this exact blister pack or if they are selling the 2nd rate single retail blister packs. I won't return it for a few dollars but I would have paid an extra 2 bucks to get the originals with an expiration date printed. I hope this helps potential buyers of this product.

Batteries had expiration date of 9/13. I expected fresh batteries. With an expiration date that soon the batteries are hardly worth installing. I requested a replacement or refund and was instructed to ship the batteries back. It cost $1.95 to ship the batteries back plus the hassle of packing and going to the post office. Hardly worth the trouble for a $3.25 item. As of this date I am out $5.20 and have not received a replacement or refund. What a waste of time and money.

Got these as a replacement for the battery used in a garage door opener. After just a few days of work, the garage door opener stopped working. I checked the voltage and sure enough, it was 7 volts, instead of 12. Energizer typically makes very good quality batteries, so this set was probably just a lemon. But still, waste of my time and money.

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

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 a package of two A23 batteries as replacements for the one that died in my garage door opener. The first one I put in only lasted as long as two uses. Thinking it was just a defective battery, I put the other one in. It lasted as long as about 8-10 uses. Good thing I was at Auto Zone that same day and they had one pack left of the A23 batteries. Yes, I paid the full retail price, but at least I haven't been let down since I put them in about 2 months ago. I don't know how you check battery life before you buy batteries online, but I guess you just take that risk.

Purchased these for my garage door opener. I was having to go pretty close to my garage door before it would open and thought new batteries would do the trick. After installing the new batteries my range increased tremendously... FOR TWO DAYS! Then my range fell back to the way it was before installing these. Could it be a defect in my remote thats sucking the life out of batteries? Possibly, but seems like they would be dead in no time if this were the case.
