More lithium and lithium-ion batteries are being used in products today and just like any material, if we understand how to use it safely, it should not pose any problem. Lithium-containing batteries, when damaged, defective or used improperly, can present a fire and/or an explosion hazard.
⚡ TL;DR: Lithium batteries are classified as hazardous materials by DOT and EPA. Small electronics contain 6 cells; EVs contain 7,000+. Batteries must be ground-shipped only (no air cargo). Damaged or defective batteries cannot be thrown in trash. Businesses must follow strict DOT and EPA rules for disposal, shipping, and worker training.
The Lithium Battery Hazard
Small items such as a laptop can typically have 6 lithium cells in them, while an electric vehicle can use 7,000 lithium-ion cells. This change in size greatly increases the risk and effects of a fire. Lithium and water don’t get along—when a battery is damaged and moisture enters, or when thermal runaway occurs from overcharging, you get fire risk.
⚠️ Why this matters: Lithium battery fires in transport are no longer rare edge cases—they’re a critical safety and liability issue. In 2023, cargo aircraft fires linked to lithium battery shipping made headlines. DOT has tightened enforcement, and non-compliance carries significant penalties. If your business stores, disposes of, or ships lithium batteries without a documented compliance program, you’re exposed to: facility shutdowns, EPA and DOT fines ($10K–$50K+), and employee safety liability.
Battery Disposal and Shipping Rules
For Consumers: Regular citizens should take used, damaged, defective or recalled lithium-containing batteries to recycling facilities geared for accepting them, or your local household hazardous waste collection point. Do NOT throw them away with your other garbage.
For Businesses: If you are a business, there are a number of regulations you need to follow to properly deal with lithium-containing batteries. First, they can only be shipped by ground methods (truck, rail or vessel)—never air cargo. Your business must classify the battery as hazardous waste or hazmat depending on condition, track disposal in your waste records, and train employees who handle them.
Do you have a lithium battery compliance program in place? Many facilities discover gaps during an audit. iSi can help you establish documentation, train your team, and ensure proper handling and disposal procedures.
Frequently Asked Questions
Q: Why do lithium batteries present a fire and explosion hazard?
Lithium batteries can catch fire or explode when damaged, defective, or improperly charged because lithium reacts violently with water. When a battery is damaged and moisture enters the cell, or when thermal runaway occurs from overcharging, the battery temperature rises rapidly, triggering combustion. Electric vehicles with 7,000 lithium-ion cells present significantly higher fire risk than small electronics like laptops.
Q: What is DOT’s stance on shipping lithium batteries?
The Department of Transportation (DOT) has issued warnings about lithium battery shipping for recycling and waste, finding the issue has become critical due to fire incidents during transport. DOT restricts lithium battery shipments to ground methods only (truck, rail, or vessel) and prohibits air transportation of lithium batteries due to fire risks in aircraft cargo holds.
Q: How should consumers dispose of damaged or defective lithium batteries?
Consumers should never throw lithium batteries in the trash with regular garbage. Damaged, defective, or recalled lithium batteries must be taken to authorized recycling facilities or local household hazardous waste collection points. Proper disposal prevents fires in waste management facilities and landfills.
Q: What regulations apply to businesses handling lithium batteries?
Businesses must follow EPA and DOT regulations for lithium battery disposal and shipping. Lithium batteries can only be shipped by ground transportation methods, and handlers must follow EPA hazardous waste classification rules. iSi Environmental provides DOT hazardous materials training and shipping consultation for businesses managing lithium battery disposal and recycling operations.
💰 Cost of non-compliance: Regulatory fines for improper lithium battery handling: $15K–$75K per violation. A single incident of non-compliant shipment can trigger facility shutdown plus reputational damage. A full compliance program with auditing and training typically costs $5K–$15K—a fraction of a single enforcement action.
