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.

I use these in wireless microphones and bodypacks. I don't buy any other batteries. These last longer than copper tops and cost half as much.

I go through these a lot working in live production. These are the best batteries and are super dependable.

Perfect for our trail cams. Long lasting batteries for the price.

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.

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!

Used these batteries at my place of work.. they seem to last as long as the top named brands, but, cost less...i will definitely keep buying...

Every other one was bad, most had corrosion on the bottom. Never again
