How To Safely Handle Rechargeable Lithium-Ion Batteries on Campus

This piece originally appeared on United Educator’s website as “Safely Handle Rechargeable Lithium-Ion Batteries” in September 2025 and has been adapted for NBOA’s Net Assets magazine.

You’ve seen the headlines about batteries exploding in planes. You may have seen happy smiles of eBike- and eScooter-riders grace your campus. If you’ve seen the latter, you may not be connecting it to the former. E-vehicles that are gaining in popularity can reduce carbon emissions, traffic congestion and, if they are small, parking lot needs, but they are not without their own risks and considerations.

Lithium-ion batteries, which can also be used in robotics classes, research labs and even campus vehicles like golf carts, can combust if they aren’t charged or stored properly. Considering their growing use on independent school campuses, educating your community on safe practices is crucial.

Educate Battery Users

Consider creating a comprehensive guide for charging and storing lithium-ion batteries on campus. Include in the guide:

• Requirements that lab managers and instructors review safety guidelines if they plan to use such batteries in their labs.
• Information for drivers of rechargeable campus vehicles on proper charging and storage practices as well as location(s) of safe charging zones, which should be outside buildings, including outside residence halls, and away from fire hazards.
• Requirements that those who bring campus vehicles that use rechargeable batteries to campus register them with the school and store them properly on campus.

Safe Charging and Storage Practices

Ensure the batteries that your institution purchases have been tested at a nationally recognized laboratory, such as Underwriters Laboratories.

In addition, include these tips in your battery safety guidance:

• Use manufacturer-provided charging equipment, not equipment intended for another device or any improvised charging device.
• Charge batteries in accordance with manufacturer instructions.
• Avoid charging devices near flammable items, especially bedding.
• Don’t charge batteries overnight.
• Remain present during charging.
• Unplug batteries once they’re fully charged.

Offer safe storage suggestions:

• Store batteries in a dry environment at room temperature, away from direct sunlight and fire hazards.
• Don’t store batteries touching each other.
• Consider using fireproof bags for storage.

Instruct users to stop using a battery and call for help if they notice:

• Odors or smoke from the battery.
• Hissing, popping or other odd noises.
• Swelling or changes in shape.
• Leaking.
• Overheating.
• Visible corrosion or damage to the battery.
