PROCELL Constant AA Long-Lasting Alkaline Batteries (144 Pack) 10-Year Shelf Life, Bulk Value Pack for Consistent Moderate Drain Professional Devices

There isn’t much to say beyond the fact that these batteries do what they’re supposed to do. They arrived in good condition, installed easily, and immediately powered the device without any issues. No signs of being old stock, no weak startup, and no leakage. Performance has been steady and consistent so far, which is really all you can ask for with batteries. If you’re looking for a straightforward, reliable replacement option that works right out of the package, these get the job done.

These are top notch, long lasting batteries at a great price.

quality battery, purchasing bulk at 39 cents per battery vs. 90 cents

We love these batteries and go through 24 every Sunday for church services. Strong enough to get us through Sunday services and the following Thursday rehearsal as well. Wireless mics, body packs, in war monitors.

Great professional grade and use batteries. Have used them for years! Bill Mahon Photo, Video and Drone

There's very little to say about batteries that work. Recommended.

Used these in multiple different timered lights. They drained faster than my amazon batteries which are far less expensive.

Gone are the days when Duracell were made in Connecticut, USA, where quality control and consistent storage environment helped guarantee having good batteries by the time they reached the buyer. Although poorly marked, careful examination shows these AA cells are Made in Belgium, and imported to the U.S. via a subsidiary in Australia. I have not encountered any problems from freezing or overheating during transport, but I already have habit of testing and examining each cell for leakage and expected voltage. Just the way it is these days. The Procell line from Duracell originally offered wholesale pricing to users who would buy large quantities at a time. Procell saved money by using plain packaging and minimal advertising. Lately the parent corporation has succumbed to market pressure, now offering these branded "Constant" cells, and a variation called "Intense" or something like that. The technical charts on Duracell's website show very little difference in practice, which should encourage people to instead pursue the best deal rather than falling for the hype of products that show a difference only under controlled laboratory conditions. I shall stick with Procell for the time being. They're better than Energizer Industrial for cell-to-cell consistency and best running time in the powered device.
