Around ~2005 one of our products was featured in a Duracell commercial.
In 2011 manufacturing for all but the 9V was moved to Tunisia and the design of the battery was changed. In pre-2011 batteries the cylinder was the negative terminal. In the newer design the cylinder is the positive. Look at the bottom of the newer ones and you will see a very small O-Ring separating the positive from the negative. It is very easy to breach this O-Ring when inserting a battery, resulting in it getting hot. Well over 100'F has been measured. The new design WILL leak.
Because of our commercial connection we discussed this with Duracell. The end result was "We don't care". Today they are riding on the reputation of the past.
We then evaluated all the batteries on the market at that time. Technically the Energizers and the RayOVacs came out the same, with the RayOVacs being cheaper we switched to those. Shortly there after Energizer bought RayOVac. Look at the Fine Print on the package today and it says they are made by Energizer.
Has anyone noticed the scam that Home Depot and Walmart, and probably others, are running? C and D cells are the same price. The marketing campaign tells us this is a Good Thing, without explaining how. If the energy density is not the same, then the price should not be the same.
