18650 Battery Safety

Plastic & silicone cases and wraps are good for transportation, a fireproof case is meant for home STORAGE, hence my initial recommendation. Only you can determine your tolerance for safety. Always make sure you have FIRE INSURANCE for home or apartment, and hope your neighbors follow proper battery safety storage and usage guidelines.

There are many products that have evolved since I bought the “BatSafe” brand, so do your own research.
I keep my BatSafe box in my unused fireplace as added insurance, hopefully you’ll never experience a lithium battery fire, taking all safety precautions as you can might be worth more in the end, then yet another vape device you probably don’t need……

I'm telling my wife what you said about her kitchen counter

I only have 1 18650 that came with my device. Now that I have an external charger with 4 ports. I am looking to get some extras. I have read that you should stay away from amazon, so can someone direct me to the best online seller for reliable 18650s? I am in the US if that matters.

What's the best way to store new batteries?
I bought a fresh batch and don't want to bring them all in rotation at the same time. Was thinking to just keep them like they came (so no charging), in a battery box in a cool room.
Or are there better ways?
How long can they be stored before they start to degrade from not being used?

From the horse’s mouth:

Lithium batteries have a supposed shelf life of approximately 10 years.
Best long term storage is to charge them to about 3.8 volts, and store in refrigerator.

Alternatively, try Battery University, but that requires more reading, thinking, and general paying attention than most of us want to put in.

I mean what’s the worse that could happen?
