I'm thinking about my Duracell...

This is really spooky. When I left for Edinburgh I put two new Duracell batteries in my Sony CD MP3 Walkman Thing and split for the door. It's over a month and a half later and they show no signs of running out, down or dry and more and more signs of running anything. I've played this thing on average for two hours a day. No three. Do the math: 3 x 7 days a week x 6 weeks since I put them in... That's 126 hours! Plus I forgot to switch it off one night and woke to find it still playing. And for the last three days I've had it on continuosly in the hope of killing them off once and for all. It must be getting close to two hundred hours. This is really spooking me out. I'm just gonna throw them out, yeh that's what I'll do, throw 'em out, real easy like...
