I'll be interested in the outcome. I've got a 430 that eats batteries. I put one in and it last 6 weeks or so... then starts reporting low battery again. Been through this a few times.
I'm getting tempted to bring the wires out the back so I can use a couple AAA's and be able to change them without pulling and opening the box each time.
