PROCELL Alkaline 9V Batteries

Big fan of these. Blown through nearly a thousand and haven't been disappointed yet using them in mission-critical mics. Can't speak to how long they last (we pop in new ones every night), except that we now have a growing pile of "partially used" batteries and we never used to have extras when we used regular Duracells. Cheap, reliable, and come with nice little plastic covers that help us tell which ones haven't been used yet. I've bought a ton, and I will continue to buy them.

We use these batteries for swim meets in conjunction with the Colorado Dolphin Wireless Swim Timing system. Each wireless timing device takes 1-battery and there are up to 18-devices on deck. That's a bunch of batteries for each swim meet. So buying them in bulk is the best option. We have not experienced any dead or low batteries out of the box. Really happy with the product. I'm certain we'll be ordering another box once these get low.

... I never thought I'd grow up to review a 72 pack of batteries, but here we are. At least 20 of them are good :) - as they are in units currently. The others are awaiting their trial by fire.

We use these for a microphone system at church. Constantly going through batteries, we had issues with the low priced options available locally. The packaging is great since they take up little space in the desk drawer. Can't get too excited over batteries. Cost per battery was better than the lower priced items and I no longer had to keep running out to get more.

Found this available a little while ago for just over $0.51/pc. Best deal I've ever seen for 9V batteries and being the commercial ProCells seemed too good to be true. The price was just too good to pass up. Placed the order and received everything with dates of 2020 expiration which was my biggest concern. So far so good.

Not sure if these are “randomly/loosely thrown in the brown box” specials or what, but the product line itself is no different than Duracell's standard Coppertop line. The difference is the Procells are sold in bulk only and not for retail sale. The voltage and milliamps test the same, though. Whether or not these last or leak remains to be seen (just received mine). I will note that, these batteries being purchased in November 2018, were dated to expire in March 2022. That's not even 3 year 4 month shelf life expected. :(

We go through a lot of 9v batteries to power our wireless microphones in our video-multimedia business. And the cost of the regular brands has gone right through the roof. The Duracell-ProCell brand has been very reliable, at a fraction of the cost of the regular Duracell's and other brands.

Better price on Amazon than I have been able to source elsewhere. Overall a great battery for commercial or personal applications
