Wallclock drains battery fast

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.

Use better batteries? Non-alkaline makes it sound like you are using cheap batteries, which aren't worth a whole lot. Some devices just don't work well when batteries can't supply enough current, and cheapo batteries power curves are worse than you think. A lot of battery powered devices like TV remotes have such low power requirements, they often mask how bad some batteries are.

Batteries have a finite amount of energy stored in them. If your batteries are the same in all of your clocks, obviously the clock that drains the battery faster is using more energy from the battery. If all of your clocks are also the same, you may have a defective clock.
