Battery life better than other brands
The only batteries that I use for many years. The battery life seems to last longer than other batteries. Power and packaging seems just like other brands.

Reliable, long-lasting battery power that’s worth
The Duracell MN21/23 Alkaline Battery delivers consistent performance and long-lasting durability. I’ve used it in small devices like remotes and key fobs, and it holds power for months without dropping off. The packaging is sturdy and easy to open, protecting the batteries well. It’s compatible with most of my devices and offers great value considering how long each on...

Durability, value, performance, packaging, compati
Duracell is outstanding for their products, I used many brands before but nothing can beat their performance and they are so value able to me. Their competitive with other brands is absolutely big win. Also, their packaging is on another level, no leak and well sealed.

Durable
While these ones may be a little pricey they tend to always do the job! They always last longer than other battery brands I have used and always work to the best of the ability I need!

Great battery
Great product that has powered all of my remotes. Would recommend for anything that requires the mn21/23 battery. The packaging is perfect for this single unit battery.

these are definitely worth
I bought the MN21/23 alkaline batteries for my garage door opener and they have been working great so far. the power seems strong and consistent. My old battery died pretty quickly, but this one has been holding up well for weeks Its nice not having to stand outside clicking the opener multiple times just to get it to work.

Reliable and long lasting
As always with Duracell you can’t really go wrong, Duracell is always my first choice when buying batteries, they are not the cheapest, but you get what you pay for and in this case, I’m happy to pay a bit extra for the quality of product.

They are very reliable
I picked up a couple of these Duracell MN21/23 batteries for my garage door remote after the old ones gave out. Honestly, I didn’t think too hard about it—just went with a brand I trust. And so far, I’m glad I did.
Right out of the pack, the remote started working again instantly, and it’s been running strong for months without a hiccup. I use that remote almost every ...

It does it's job.
Fine battery... does the job. But be aware that you are getting the size you need. I was looking for 21/23 size and somehow ended up getting a N size battery (very close size but 1.5 volt). It was a google search issue as it was the first choice on the search and I didn't read the small print. I will have to return that one to the store. This 21/23 size does the job...

Hard to Find But Easy to Get
These batteries are for a 44-year-old Sears Craftsmen garage door opener and are usually difficult to find. Google told me that Staples has them and I picked them up within 48 hours of ordering them. Great experience - thanks Staples!

I loved it! Because
I loved it! Because it lasts a long time, I used it to my electric teeth brush, and it stays the same as the first time, and yes!! It met my expectations, because I’ve bought some other batteries and they didn’t work as well as this one did!! I totally recommend them!!
