Greetings SE,



I own one of these and I'm assuming they have button batteries inside them. I have to press the button on mine sometimes 5 times or more now and I'm worried the battery is finally starting to die.

I have a few questions:
Is it possible to pry these things open and replace the battery myself?
Is there a different way to go about it?
What kind of battery is actually in there anyway? Is it a simple button battery i can buy in stores?
