The TSA limits for batteries include voltage and watt-hour ratings for safe air travel.
TSA Battery Regulations
The Transportation Security Administration (TSA) has specific regulations concerning batteries in carry-on and checked baggage to ensure safety during air travel. These regulations primarily focus on the battery's voltage and watt-hour (Wh) rating.
Key Limits:
- Voltage Limit: The battery voltage must not exceed 12 volts.
- Watt-Hour Limit: The battery watt-hour rating must not exceed 100 watt hours.
Additional Safety Measures:
Besides the voltage and watt-hour limits, the TSA requires that battery-powered equipment is protected against:
- Accidental activation
- The evolution of heat
- Damage to the terminal posts
This can typically be achieved by:
- Ensuring the device is switched off.
- Using recessed on/off switches or a switch lock.
- Removing the battery.
- Covering exposed terminals with tape or placing each battery in a separate protective pouch or case.
