The first time I heard about how dangerous lithium batteries can be was on a plane. The airline mentioned that you can’t store lithium batteries, especially underneath the plane, because they could overheat and explode, causing a fire. That doesn’t sound good for a flight!
The airline industry realized there were issues with lithium batteries and started issuing notices, particularly from TSA agents, warning passengers not to put them in their luggage. They go through a specific process because these batteries can experience something called thermal runaway, which can cause them to catch fire. They can overheat from being overcharged. I often find myself in a situation where my son says, “Mom, stop overcharging things!” I want to ensure that I have a reasonable charge on my devices before getting on the plane. He worries about it because he knows that overheating could damage my nice computer.
Talk to Your Customers About Storing Lithium Batteries

I think it’s essential to reflect on what your customers are storing, especially after learning that. At a minimum, I recommend having clear signage around the property. For example, you could put up a sign that states, “No lithium batteries allowed in storage spaces.” This is important because storage owners should inform customers about potential risks. If they are storing e-bikes or similar items that could pose a fire hazard, it’s crucial to communicate these concerns.
Fire incidents have occurred in storage facilities, so don’t assume that it can’t happen to you; it can, especially in hot regions like Arizona, where temperatures can reach 118°F. The inside of a storage unit could be even hotter depending on its construction. When talking to your customers, consider these factors and ensure you have adequate signage around the property.
Be Prepared!
Additionally, it would be beneficial to have fire suppressants readily available on-site. For instance, you might consider using an extinguishing agent that displaces oxygen, effectively suffocating the fire and preventing it from reigniting. Having something like this in your maintenance unit could allow for an early response if a fire does occur. This agent absorbs thermal energy, which is key in controlling a small overheated situation before it escalates.
Put a Clause in Your Rental Agreement about Lithium Batteries in Storage Spaces
It’s also crucial to update your rental agreement regularly. Many owners tend to keep it unchanged, but I believe it’s important to review and modify it yearly. My trusted attorneys in the self-storage industry advise me on these updates. For example, adding a clause about potential fire hazards, especially in non-climate-controlled units, is vital given the risks in areas like Arizona.
