You'd think so but every device around my house that I "put batteries in it and forget it" when I need it I find the batteries have exploded and the device is ruined (regardless of the decade on the expiry-date label of the battery). So my plan now is to keep the device separate from the batteries like it's a freaking handgun and make sure my phone is charged so I can use its light to make my way to the drawer where we keep the batteries.
Alkaline batteries are the crappy ones that leak. Get the more expensive lithium batteries, or go full on rechargeable ones, and you can leave them in without worrying about your device getting ruined.
Lkline leaks, lithium explodes
Yeah but at least you'll know exactly when the lithium ones go bad...
Rechargeable batteries self-discharge and get damaged if left unplugged for too long, and explode if left plugged in. They are not ideal for something you want to pack away in an emergency kit.
Almost everything in an emergency kit expires. But many name brand alkaline and non rechargeable lithiums are now rated for ten years shelf life. In addition there are rechargeable eneloop branded batteries rated for slower discharge rate.
Yes, but there's a difference between "expires" and "leaks all over the inside of my emergency radio". And they don't make it to half their stated lifespans once put into a flashlight and the flashlight goes into storage.
