ProCell 12 Alkaline Batteries, 9V, 12/Box

Our entire family uses these based off their performance in our homes, as well as one of our family members that uses them at work. Great value and long-lasting, I recommend them to my friends. The value pack allows you to replace all the 9v in our smoke alarms at once, with enough left over to do it at the next solstice and crafts/other needs along the way.

Just received a 12 pack of these barriers. To help the next person, when you get your barriers, you can find the date on the side of the barriers (see picture). These are good thru March 2030, ordered them on 12/29/25.

Made by and as good as Duracell, but less expensive.

Great batteries for my active basses/guitars. Voltage read good on the 4 or 5 randoms I pulled. Discounted boxes are usually older like mine, but still work well.

First, important to note that there is likely some variation with some users experiences due to the source - different stock has different expiration date/ages, some may actually not be authentic, and some may have some other factor rendering them less than able to perform well. Make sure you always buy from a reputable seller, of course Amazon directly but if not from an authorized dealer or someone with a great history. Otherwise it is possible you may get poor quality ones or fakes etc. That being said - we have been buying these Procells (not just 9V, all the sizes of the Procell line) for many years now and have been consistently pleased with their performance. They are used in both home and work environments and with some being put to the test (10+ hours of consistent use, very hot outside weather environment and so on) and have had nothing but a great turnout with all of them. Pricing is slightly higher but they are somewhat easy to find from both Amazon and other SBA and similar sellers at a lower cost - however - worth every penny even if you're paying a premium. I believe the lowest we have paid for this box of $12 was around a dollar a battery, and the normal price looks to be around $15 which again is totally worth the little extra over some other brands. We will continue to buy the Procell line but definitely sticking to sold by Amazon just to make sure what we are getting is real and fresh :) Also, just to note - the thumbnail here shows the old red and black box, we got (5/2016) the new yellow/black box.

The only thing I generally need replacement 9V batteries for are my Smoke Detectors. I have 12 foot ceilings and 9 detectors so I'm not anxious to replace them more than necessary. I know the "rule of thumb" is to replace the batteries every year on your birthday (easy to remember). But, at my age, I'm not wanting to be on a ladder much any more. So, what I have been doing is to wait for "one" of the detectors to start squealing the "low battery" tone. Then, I replace all 9 at the same time. I do use a marker to record the replacement date on each battery for whatever later reference. The last time I replaced these was about January 2017. They then have lasted about 3 1/2 years before the first one started "squealing". The "use before date" on the pullouts was "March 2019", about a year before this recent replacement. Therefore, I have been quite satisfied with the longevity of these batteries. Longevity is one thing but "leaking" is more important as it can damage, sometimes permanently, expensive devices. I have never had a Duracell Procell leak. I do use "cheaper" batteries, including Amazon Basic cells, in some things without trouble. I don't really have any quantitative data, but, over the years I would say that Duracells leaked less and "Bunny" batteries more. I'm sure manufactures are continually trying to improve battery performance, but, there's always cost-reduction efforts and "outsourcing" which can affect performance. When possible, I remove batteries from devices not in frequent use. Then, I tend to only use cheaper batteries in devices I really don't care too much about, like home Christmas displays.

Great Product, just what was needed.

Good deal with good delivery time.

as a musician I use these 9 volts for pedals or smoke detectors.this last batch,the power drops fast ,used fade out more slowly but still good value!

I was happy with the general transaction. My only comment is that the self life on the batteries is June 2024. A lot of the batteries I have ordered have a shelf life of 2028+ So it seems like it may be old stock ?

De las mejores baterías que puedas encontrar

*** Great Product ***

These are the best batteries I ever used and don’t seem to be as sensitive to cooler weather as most batteries
