Well this surprised me! The Rayovac (I should say, This Rayovac, with the blue label) followed the discharge path of Duracell pretty closely. Much closer than the Energizer. We will see how it holds up under a constant current of 400mA.
I was going to wait until tomorrow to add the results of the 400mA constant current discharge, but It was done when I woke up so I decided to post it as well before heading off to work.
This test would almost make you wonder if Rayovac is just Duracell in different clothing. It's not, the mechanics of the case are different enough between them. Still, those discharge curves are Close!
