This is a bit off-topic from computers and other electronics. I'm just wondering why a wall clock dries out a battery faster than other clocks. You see, I have 5 wall clocks in my house and there's this certain clock that needs replacing the battery quite frequently than the others. All the other 4 clocks need replacing the battery maybe around 5 to 9 months, and this one dries out at around 2 to 3 months. I wonder why? All clocks run on single aa regular non-alkaline batteries. And no, all clocks don't have any other functions but to tic-toc. Thanks for any incoming replies.
