Almost every handheld computer produced since early 2000s runs on a Li-ion battery. When you become serious about collecting handheld computers, you end up storing quite a large amount of batteries in your home. In this case you should consider taking safety measures for storing batteries, because a Li-ion battery is a potential fire hazard.
Here are the very basic principles of storing Li-ion batteries:
- Batteries should be stored in fireproof containers.
- Do not expose the batteries to high temperatures (e.g. direct sunlight).
- Prevent external short circuits (store batteries in separate insulating bags).
- Prevent internal short circuits (prevent mechanical damage).
- Batteries should not be stored with other products that could accelerate a fire.
And, of course, keeping a fire extinguisher in the vicinity of the storage area is also a good idea.
