I find that these batteries are not fully stocked in most stores due to the wireless technology that drives a lot of the electronics for which these are used. When you need this specific type of battery, however, this is one of the best deals you will find for them. In stores, possibly because of the low demand for them, they typically cost $6.00-$7.00 USD for a package that contains either two or just one battery. Six batteries for this price is an absolute steal. You may find other deals on Amazon where there is a boastful amount of batteries for a low price, but these often come in unmarked boxes where the quality and usage of the battery cannot be easily determined. It is always best to choose the item that is properly packaged.

Additionally, while a lot of competing brands such a Energizer boast their exponential output, I have always found Duracell to be far more reliable. You can find this same battery made by other brands, but Duracell is just a personal preference for their continuous reliability.

I gave this 4 stars instead of 5 is that while the listing is for the Duracell Duralock version of these batteries, I only received the normal version (as pictured with the photo attached). If you have this problem or suspect this might be an issue, message the seller before purchasing them as it is the seller's responsibility to deliver the correct product. On the plus side, these batteries were definitely not old and have an expiration date of 03/2019. While I would have preferred the Duralock batteries, I am at least happy the ones I receive have a fair shelf life.

If this review was helpful to you, feedback would be appreciated. :)

These batteries in the store cost more for one single, than this two-pack online, delivered (I bought with other items and got super saver free shipping). The shelf life was well into the future, and they are a well known name. I use this battery for a wireless bike computer.

Unfortunately, the negative reviews are correct. The batteries have a limited shelf life, far less "fresh" than those you can purchase in retail stores.

Update to the original review below: The supplier contacted me very quickly when I complained, and offered me my choice of a refund or replacement. I chose a replacement, and they also arrived very quickly. The package was intact, no damage, and although the batteries were slightly less than I would like for brand new 12V batteries (12.10 and 12.19 V), they were still above 12.00. I have updated my original 2-star rating to a 4-star on this product, and I credit the supplier with such rapid response and trying hard to satisfy me, and would recommend working with them.
=====

When I opened the shipping package, I found the batteries loose inside. Also loose was the Duracell paperboard package and the plastic blister. The date code on the package said the year 2015, but the voltages were less than 12V: 11.98 and 11.90V. They should have been substantially above 12.00, such as 12.30-12.70. Either these batteries were not truly originally in the package, or they were factory seconds with less than specified voltages.

Great batteries from Duracell that I use in a Coyote call. I check the voltage on all batteries that I by now because I recently bought a 48 pk. of AA batteries w/a 2023 expiration date and found 18 of them below 1.5 VDC. one was actually measured 0.03 VDC. I called P&G to tell them about it and they made it right w/replacements.

I use these batteries for my garage door opener and they are not sold everywhere. It was much easier to find them on line and order them. The great thing was I got them for an excellent price. I will continue returning here for all my battery needs.

It's so convenient buying through Amazon....these are a size battery that I would need to make a special trip to a big chain Home Improvement store. Good value also....Duracell is almost always my first choice in a battery!
