Additional Battery Guidance
Types of Batteries
There are many kinds of batteries available today and several are regulated as hazardous materials in transportation that may only be shipped by contract hazmat shippers.
Lead-acid batteries
Common in cars, electric wheelchairs, some continuous computer power sources, and other applications. These batteries contain highly corrosive acid and can cause fires from short circuits.
Non-spillable batteries
Tested, proven non-spillable batteries are allowed to be shipped as non-hazardous within the U.S. Batteries and packaging must be marked "NONSPILLABLE" or "NONSPILLABLE BATTERY".
Lithium and lithium ion batteries
Both rechargeable and non-rechargeable power sources, common in computers, cell phones, cameras and other small electronic devices. If dropped, crushed or short-circuited, these batteries can release dangerous amounts of heat and may ignite, and are dangerous in fires. Special regulations apply to shipping these batteries.
Other Batteries
Although common dry cell (e.g., AA, C, D batteries) may not be regulated as hazardous materials, all batteries can cause fires from short circuits if batteries and terminals are not protected.
Protect Batteries and Terminals
When shipping batteries, you must protect all terminals against short circuits by completely covering the terminals with an insulating material (e.g., by using electrical tape or enclosing each battery separately in a plastic bag).
• Short circuits can cause fires.
• Package the batteries to keep them from being crushed or damaged, and to keep them from shifting during handling.
• Always keep metal objects or other materials that can short circuit battery terminals securely away from the batteries - e.g., by using separate inner box for the batteries.
Prevent Fires

Any device with installed batteries must not turn on while in transport. Protect switches that can be accidentally
activated, or remove the batteries and protect the terminals.

- Even very simple devices like flashlights or rechargeable drills can generate a dangerous quantity of heat if
accidentally activated.
Recalled or Recycled Batteries
Never ship recalled or recycled batteries by air.
Electronic Items for Repair
Repair items, such as computers and cell phones, should be sent without batteries.
