Review on 🔋 High Performance Procell 9V Alkaline Battery Bulk Pack - 72 Batteries per Package: Long-lasting Power for Your Devices by Denise White

Not sure if these are "accidentally/negligently tossed in a brown box" specials or something, but the product line itself is no different from Duracell products. Standard Coppertop line. The difference is that Procells are only sold in bulk and not for retail. However, voltage and milliamps are tested in the same way. Whether they will be the last or a leak remains to be seen (just got mine). I note that these batteries purchased in November 2018 had an expiration date of March 2022. This is not even the expected shelf life of 3 years 4 months. :(
