DX 1253 keychain runtime?

[pbs357]

Hey all,

Does anyone know how long these little keychains will stay lit on a fresh battery? These seem like a no-brainer keychain light but I was wondering if there would be any point in ordering a bunch to strategically stow away for emergencies, etc. Thanks! :wave:

It's an exponential runtime. However, they are great to stash all around the home or office. They are cheap enough to put absolutely everywhere, and are there when you need them.
