How to Store Lithium-Ion Batteries
“By minimizing exposure to the conditions that accelerate degradation, batteries can last longer.” -Greg Keoleian, Director, University of Michigan Center for Sustainable Systems, School for Environment and Sustainability.
I love batteries and you love them too, so in order to make sure they last long and stay safe, batteries need to be stored properly. The obvious tips are: Avoid high-moisture, avoid mechanical damage like smashing and puncturing, avoid extreme temperatures, avoid corrosive chemicals, basic common sense things like that. What else do I need to know about storing my lithium ion batteries?
It's recommended for batteries be stored away from sunlight, heat, and humidity in a storage area that is ventilated and dry, maintaining a relatively steady temperature. Ideal battery storage temperature is ~59°F (15°C). High humidity is bad for batteries, so the ideal humidity is 35% to 65%.
State of Charge
Store your batteries at~50% charge, but if you're not going to recharge in a few months then store fully charged.
Do not store your batteries in any plain ol' metal container, instead use a plastic battery box. Make sure to avoid coins or other metals in the same box. Use tape or plastic caps to cover the terminals if you can't guarantee the positive terminals won't be in contact with the negative ones (if batteries come in contact with metals, they can start conducting electricity). News flash! Batteries can be dangerous. Storing batteries inside your home is not ideal. An unattached outside shed is a better idea. Whatever the location, for max safety use a battery storage cabinet.
Organize and separate your batteries. Mixing new and old batteries can be dangerous, so keep track of how long you’ve had your batteries by labeling them.
