Questions & Answers

What is the expiration date for the product?

I ordered these in June of 2019 and received them in July of 2019. Only one day had passed since the expiration date. In five years, DEC 2020. For such high-priced batteries, this is inexcusable. And that they've been shipping out newer product for the past six months: It indicates that Amazon's inventory isn't being rotated properly. As a product distribution company, this is their job. That's all I have to say on the subject. If you buy batteries from Amazon and have them shipped to you, don't expect them to be brand new. (It's too bad.)

Is this a brand new battery? Or do they show up with only a year or two left on their expiration date?

The 22nd of March is the date on my batteries. According to the package, there is a 5-year storage guarantee. I get a lot more use out of this battery than any of the others I've tried. My TENS units are the only thing I use them for.

Can these charges be used in a Lithium-ion battery? Is there a charging bay for ion batteries?

Nope. They aren't being resurrected. to be paid

Is it possible to use these with a smoke alarm that requires a 640p 9v battery?

This battery should work fine in a smoke alarm.

BEWARE OF OLD BATTERIES
3/5

The "Quantum" 9v batteries have a best before date of December 2020 and were delivered in December 2019. These are advertised as having a 5-year warranty by Duracell. I've since discovered that Duracell discontinued the "Quantum" battery line in August, replacing it with the newer Optimum line, so I paid for premium batteries and received 4 year old discontinued batteries.

Batteries that have seen better days
3/5

Old batteries are definitely being sold on Amazon. My receipts are dated 3/2023, and I purchased them on January 1, 2020. A 10-year warranty should be included with the new Duracell batteries. There is a 5-year warranty on these old ones. Although they will most likely be fine, the description is technically incorrect.

BUYING IS A MISTAKE - SCAM! Customer who is extremely unhappy! This was purchased three months ago, and the battery has already died
3/5

Years later, the batteries I purchased at the store are still functional. The expiration date is December 2020, so there's no reason to believe this "better" product has already expired. This is the last time I'll buy from this seller.

Expired? No
3/5

However, there are no new batteries. The battery's expiration date is December 2020, which is one year away; these batteries are supposed to last 5 years if purchased new. br>The packaging appears to have spent some time on the shelf.

battery that has been used before I ordered these batteries to keep on hand for when I need them
3/5

In storage, these batteries are expected to last 5 years. These batteries were ordered in December of this year, but they will expire in December of 2020. I would not purchase these items again.

The batteries I got have a three-year shelf life! My package did not look exactly like the one in the picture
3/5

Take a look at the image I've included. br>br>More significantly, the batteries' expiration date - You can see it in my photograph once more - is December 2020, which means the battery will only last three years. I usually receive a 7-star rating. 10 years.

50% charge on new batteries because they are old batteries they are old batteries they are old batterie They include the battery checker to demonstrate that you are receiving three half-dead batteries
3/5

I checked them with another battery checker I own and they were indeed three half-dead batteries. batteries that are no longer functional.
