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

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

Great product just as described

So long as Duracell makes these Procell's, I'll get them. I started getting them while a musician in LA because they were the only ones we could rely on while touring. They've never let me down in all of my year since. IYKYK.

been using these now for 3 seasons and I wouldn't use anything else. these batteries are made for trail cams. I run 18 cameras from May thru December and one set of batteries last the whole season. when you buy in bulk, they are a real bargain.

Best for wireless microphone. We use them in church for hour to hour and 20 min, and they last 4-5 services which is over a month for us whereas the regular batteries would not last us 1 full hour. Only for microphones, we have used them for in-ear monitors and the battery drains faster

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

Years ago, I did battery research and found that Procell was generally listed as the best, even better than Duracell Coppertop, their sister brand. After trying many brands, including the Coppertop and Energizer ones, I found that Procell lasted far longer. In fact, in my indoor sensor lights, they last 2 to 4 times longer than regular batteries and 1.5 to 2 times longer than other premium batteries. This has allowed me to add multiple extra lights which otherwise have cost too much to operate. Every time I foolishly fall prey to a sale or fancy advertising on another brand, I end up back with the Procell. I highly recommend them!

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.
