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
NEDA: 1811A
IEC: 3LR50
Panasonic: LR-V08

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.

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.

The little batteries were in no hurry to reach me, arriving toward the end of the expected delivery range. But when I saw the same package at Walmart for more than $5 higher price, the wait seemed well worth it. The battery is for a remote control on a ceiling fan. The original battery lasted almost 13 years, so I don't need 2, but even the Walmart package contains 2. I just can't avoid it. For the price, though, I think it is a very good deal.

Very disappointed. I purchased this on August 31, 2015, but have only just verified the voltages on my 6 2-pack A23 batteries from All Photo Inc. Get what you paid for...

Since the range on my community-gate remote control decreases very quickly, I decided to test the voltage on all my batteries. The voltage ranges between 8.8 to 9.1 volts for every battery; this is only 75% of capacity (if only rechargeables are made...). The A23 is supposed to be a 12-volt battery.... All unopened packages were dated 03/2018; it is currently November 4, 2016.

For reference, my Duracell AA battery is rated for 1.5-volt and dated 03/2025; it tested at 1.5V which is proper. My Energizer AAA battery, dated 03/2023, registered 1.5V which is also proper. My Desay AAA (included in some device I purchased) is dated 02/2015 and tested at 1.35V after brief usage; this is currently at 90% of its capacity.

Looks like I might need to purchase locally instead..

I purchased this product expecting 6 packs of two batteries exactly as pictured and described. Instead, I received 1 clear clamshell package with all 12 batteries in it, not sealed and no expiration date on the battery. I have no idea how old these batteries are or when they expire.

As for the batteries, so far they work but we'll see how long they work for. I use them in a garage remote, and a ceiling fan remote. I will update this post once my first battery dies.

On a side note, I was refunded the purchase price for the batteries.

If your keyless entry remote seems to be acting up (works intermittently) be sure to check the voltage that's left on it since the problem might be that the battery is about to run out. Mine didn't want to work half the time and sometimes it would only work from a really close distance. All my problems went away once I changed the battery.

This did not arrive as a two-pack of batteries. It arrived as two single packaged batteries (each in energizer packaging) in a zip lock bag. I installed the first battery and my device did not function. Upon checking the battery with my multimeter, the voltage was 8.9V, vice the 12V it should have been. When I order two batteries, both should be new, in date, and should provide the voltage required.

Save your money, buy it at wal mart.

Keeps my garage door remote doing what it's supposed to do for years and years.

Store the excess batteries in the fridge, and they'll be ready to go years down the road when you need them.

Bought these to power up a few small strips of LED lights, and they are great! The give it enough power and it lasts a long time. I've been using the fake Nightwing stun sticks I made on and off for the past week, and they are still going strong. Don't know how long exactly these will last, but I already bought extras in case. I like these a lot because they don't cause the LED lights to get hot like the power cord I have does. Then again, I'm new to this, so my power cord may just have too much voltage. Overall, I really like these and highly recommend them.

If you order the 12 pack, and it says 6 x 2 which to me means, 6 packages with 2 batteries in each package.

Well, with the 12 pack, all of the batteries came together in one plastic container. NO 6 packs of 2 each in each pack. It seems to me that I ordered a bulk order with all the twelve batteries arriving in one plastic container with me having no means to know when they were charged or manufactured. Kind of a bit of false advertisement with the 6 x 2 statement. In all fairness, I tested all the batteries when I got them and out of the 12 batteries, 5 of them registered slightly lower than a full charge of 12.65 volts. The rest were ok ....

I should have just ordered the other energizer package in Amazon for 8.91 which stated that all 12 batteries WERE in one package. I did not do that because I wanted to feel fairly certain I was getting fresh Energizer batteries. Instead, they got me for 11.00 and sent me the package for 8.91..
