How to Store Lithium Ion Batteries

by Erica Roth

Rechargeable lithium ion batteries are commonly used in electronics, including computers, cell phones and other portable devices. The batteries can be stored when not installed in an appliance, for a period of time without irreparable harm. If lithium ion batteries are stored in conditions that are too hot or cold, or without any charge, they may not be able to be revived when needed.

Using a battery charger that is meant for lithium ion batteries, charge your batteries. Lithium ion batteries should be charged at least at 40 percent to avoid future charging problems. If you battery is completely without a charge, you will need to charge it for about half an hour to get to 40 percent.

Find a cool, dry place to store your lithium ion batteries. Avoid storing your batteries in the basement, bathroom or other areas of your house that are or may become wet. Ideal temperature ranges for storage are between 0 and 60 degrees F.

Refrigerate your batteries if you do not have any other place to keep them that is temperature-controlled. Remember to use the fridge part only and not the freezer, which can become too cold.

Avoid placing your batteries in a drawer that is in direct sunlight for any part of the day. Lithium ion batteries may explode if they are exposed to extreme heat or light.

Take out your batteries and partially charge them or use them in an electronic device, however briefly, every few months. This will revive the charge and prolong the battery's life. A lithium battery slowly loses its charge even when it is stored.
