In my company we are trying to understand how can you reverse the polarity of an alkaline battery and then come up with a solution for that. We have a product that uses three AA batteries (the brand is Energizer Industrial...but it's really a normal battery). The thing is that, in some cases, we have found that the customer gets it dead on arrival. When we get the product back for investigation and we test the batteries, we find that two are somewhere in the 0.8 V range, but there is one that is always like -0.2 V. And it's always the same one (the one at the bottom - the battery housing is vertical). Nobody has been able to really answer how is that possible. We called Energizer and they cannot figure that one out either. I checked in several forums an found that customers have also had the same problem with a certain model of Canon camera. So this proves that it can happen. But, how does it happen? Why does it happen? What could solve the problem?
