Does anyone use these guys? I have one that is in the normal rotation and I haven't thought much of it, but I am doing 'hit counts' on all my batteries and I just did one on the DSE and it blew everything out of the water including the high cap (evo style) M401 batteries. It got into pen style territory. I am going to give it another test before I get too hasty but for those who have used the DSE401 batts do you notice that it goes on forever? Did I get a freak? To add to the mystery it is one of the older batteries I have.
