A recent discussion among self-storage owners is the issue of storing lithium-ion batteries. It’s very likely that there are some of these batteries stored in every self-storage facility across the country. Since self-storage owners do not monitor what is stored and rely on the honor system of a binding contract, it’s impossible to know what’s being stored in a unit.
What is a lithium-ion battery?
According to the Clean Energy Institute, “The lithium-ion (Li-ion) battery is the predominant commercial form of rechargeable battery, widely used in portable electronics and electrified transportation. During a discharge cycle, lithium atoms in the anode are ionized and separated from their electrons. The lithium ions move from the anode and pass through the electrolyte until they reach the cathode, where they recombine with their electrons and are neutralized. The lithium ions are small enough to be able to move through a micro-permeable separator between the anode and cathode.”
Think of your scooters, electric bikes, electric vehicles, and even your cell phones. Those items all use lithium-ion batteries. Proper use and storage is required, or they can be potentially hazardous.
How can I properly store lithium-ion batteries?
According to the National Fire Protection Association, “lithium-ion batteries are increasingly found in devices and systems that the public and first responders use or interact with daily.” The NFPA also provides education and tips for usage, storage, and repairs.
- Purchase batteries that are only listed by a nationally recognized testing laboratory and labeled accordingly.
- Stop charging a battery once it is full.
- Use charging equipment that is only compatible with your device. To be safe, use only the charging equipment that is supplied with your device.
- Stop using your device if the battery shows signs of damage, such as an unusual odor, excessive heat, popping sounds, swelling, or a change in color.
- Have all repairs performed by a qualified professional.
What does this mean for self-storage businesses?
We recommend that business owners specifically address lithium-ion batteries in their storage contracts. As with other commonly prohibited items, such as food, flammable materials, wet goods, plants, or unregistered vehicles, you can choose to ban lithium-ion batteries in your facility, as many peers are starting to do. This decision can help reduce fire risk and liability.
It will be important to outline with each tenant what is permitted and what is not, and to go back to all current tenants and let them know that these types of batteries must be removed from storage.
In a recent visit to the local fire station, we asked what the number one issue they received calls for was in the area. The number one reason they are called to homes is bathroom fans, but they were quick to mention that the number two reason for calls is lithium batteries. The firemen said that many individuals will not follow the safety rules outlined above, which can lead to fires. Additionally, these batteries burn much faster and hotter than other batteries, making a dangerous situation worse.
