Duracell Procell 9 Volt Batteries, Pack of 12 (Packaging May Vary)

If you are like me, you must hate buying batteries at the store because: a.) they are grossly overpriced. b.) most stores do not sell them in bulk. c.) most stores have a poor selection of brands available. I needed to replace the 9v batteries in all of my smoke detectors and didn't have much time to shop around, so I stopped in at the local rite-aid store that was closest to my house, and was disappointed to find that the best deal was a 4-pack for about 12$. Begrudgingly, I purchased those, went home, and immediately went online and ordered the Duracell ProCell 12 pack for about $16 which was much more cost effective. It will be hard to beat this price (~1.3$/cell) at almost any store. I paid ~4$/cell at the local drugstore. Sure, maybe walmart or a hardware store may have bulkier options at a better price than a drug store. Even if they were the same price as the Duracell Procell batteries, you still cannot beat the fact that these will ship straight to your door at the click of a button and save you a whole trip, gas and more importantly valuable time. But, are the Duracell Procell a quality set of 9v batteries, as well as cost effective? Quite honestly, this is the first time I've been impressed by a pack of batteries before, but these 9v batteries have many features that show attention to detail and prove that these batteries are of the highest quality. - The batteries are assembled in the USA (Link for Assembled vs. Made in USA http://www.nspa.com/documents/AssembledvsMadeinUSA.pdf) - Expiration Date: Every battery was rated until Mar 2020. - Size: Standard 9v Cell, Fit perfectly inside my Smoke Detectors and dimensions matched the previous energizer 9v cell exactly. - Voltage: No Load - Every battery measured 9.62v on my voltmeter. - Protected terminals: Each cell is equipped with a protective plastic cover to prevent inadvertent discharge and maximize lifetime of the battery. - Satisfaction is Guaranteed: On the side of the box is a guarantee against any material and workmanship defects, and an offer to replace any item that was damaged by these batteries. There is a phone number listed; however, based on the superior quality of this product I expect the company is losing money by hiring an employee to man phones that never ring. Overall, the price, packaging, and quality of these batteries is excellent! I've noticed a few 1 stars due to issues with the quantity received, or 1 or 2 with low capacity. My recommendation if you do happen to have this issue would be to contact the seller, see if they will resolve it, and if its an issue with capacity contact the service phone number on the box. The caps on top of these batteries make it very easy to measure their voltage with a voltmeter when you get them.

Duracell Procell 9 Volt Batteries are the best 9 volt batteries I have found so far. They are powerful, long lasting, and dependable. Amazon offered these batteries at a bargain price, far cheaper than any local brick and mortar store. This pack of twelve 9 volt batteries means I have a ready supply on hand when I need them. And where I live, having a ready supply is more than just a convenience. I live in the middle of 100 wooded acres, and my rural location is quite far from a town. So not only is a trip to town sometimes inconvenient, during times of severe weather when trees here fall and block my driveway or heavy snow makes leaving here difficult, it's nice to have staples like these Duracell Procell 9 Volt Batteries stocked and readily available. And being an Amazon Prime Member, I get these Duracell Procell 9 Volt Batteries delivered to my residence with free shipping. How great is that?

Needed to replace a dozen smoke detector batteries and these are perfect. PRO’s: - Eleven of 12 batteries tested at 9.73 Volts (I did not test the one that went into a beeping detector at 4AM this morning - why do the old ones ALWAYS fail in the middle of the night?!?) - Duracell brand (Procell is the “For Profession Use Only” version) - Total cost was only $1.60 per battery - Bulk packaging is SO MUCH easier than blister packs, I like the plastic terminal covers - Purchased July 2022, Shelf Life Date on Batteries Mar 2027 (close to 5 Years) CON’s: - Made in China (I’ve been trying to boycott that, too bad it’s not possible…) NEUTRAL’s: - Warranty is not usable for retail users (fine by me) - I don’t have any load testing data, but these worked fine in my detectors and I trust the Duracell brand - These are labeled for “Low Drain Devices” (again, fine by me) Overall: 5 Stars.

I bought these batteries for my equipment, and I am very satisfied with their performance. They are long lasting alkaline power cells that deliver consistent and reliable power for various devices. They are also easy to install and remove, and they do not leak or corrode. I use these batteries for my tools, machines, lights and other applications. They work well in different temperatures and conditions, and they have a long shelf life. They are also affordable and come in a convenient pack of 12. I trust Duracell porcello batteries to keep my equipment running smoothly and efficiently.

Fresh and Good! TOP Quality round cell 9v battery!!

Excellent value for replacing batteries for the time changes.

For the record, the ONLY difference between Procell and Coppertops is packaging and marketing. They are the same battery otherwise, spec for spec, graph per graph... look them up. Procell batteries are aimed at "professionals" who don't need retail packaging. Only Coppertops come in blister packs that can be hung on store shelves. Procell batteries come in bulk packaging for easy use, distribution and access. All this aside, they are great batteries. My warning to online buyers is that you don't know how old your batteries are. These batteries have a 7 year shelf life, quoted from the Duracell website: "Procell batteries deliver outstanding performance with a 7-year freshness guarantee backed up with date coding." Knowning that, I would really like most of that life to be on my shelf, not the store/warehouse. I received batteries on 5-1-2012, they are date marked to be good til 2015. That means my batteries have been sitting around for 4 years. Knowing I'd like to get at least 1 year life out of the batteries I should really use them by 2014. That shouldn't be hard since this house has at least 10 smoke detectors. But just be warned if you are buying in bulk and check the date upon arrival. I appreciate sellers that list the expiration date. Beware of really low prices, as they may have batteries with only a year or so left. Hope some of this clears up the misinformation out there. Before you buy, check out this product and see if its a better price... it is the same thing: DURACELL 9 Volt PROCELL Professional Alkaline Battery, Pack of 12

Well, every single one of the 12 9 Volt batteries came completely dead, that is, no charge. I tested every single one of the 12 batteries with -- not one but two -- properly working battery testers. How do I know my battery testers are working properly? Well, I know because I use them on a weekly basis. I've uploaded photos showing the battery charge status of 10 out of the 12 batteries. I have difficulty believing that it's just coincidence that all the batteries were dead. I think the seller is trying (or tried) to get rid of old product, hence the discounted price. And, please no one insult me with a retort such as "well, you should have known." I believe the expectation in any civilized society is that there are some reasonable man's standard of what is considered acceptable ethical or moral behavior -- even in business. I don't believe that anyone intends to buy batteries that are dead on arrival. To make matters worse, when I tried to return the item through the amazon.com web site, the message appeared that said "no returns on this item." I can only hope that I will in fact get a full refund as I requested (no gift card but full refund). I'll follow up with another post to inform the community of the outcome. I recommend avoiding this seller like the plague.

Las utilizo para el funcionamiento de micrófonos inalámbricos en instrumentos musicales ofrecen un excelente rendimiento y duración

Son baterías profesionales, soy músico y las utilizo en la guitarra y sistemas inalambricos de in ears e instrumentos, gran calidad a muy bajo precio.

Buen precio y duración

A bit pricey compared to other 9V batteries but hopefully will provide a higher grade of service. Will be using in critical applications such as smoke and carbon monoxide alarms.

Batteries work great, no concerns
