DID YOU KNOW?
Sony created the first commercial cylindrical lithium polymer battery in 1996. [2] Today, LiPo (lithium polymer) batteries power everything from drones to power tools — but they also come with serious fire risks if stored or charged improperly.
KNOW THE RISK
- Lithium polymer (LiPo) batteries are lightweight and powerful, making them ideal for many electronics and tools. [1]
- However, their chemical composition makes them more volatile than other battery types, with a risk of swelling, fire, or explosion when damaged or overcharged. [1]
- Improper charging, punctures, or exposure to extreme temperatures can all trigger thermal runaway — a chain reaction that causes batteries to catch fire. That’s why special storage and handling is essential.
MITIGATE THE RISK
1. Never Leave Batteries Unattended While Charging
- LiPo batteries can fail suddenly if overcharged or damaged. Always stay nearby when charging and remove them from power when finished. [1]
2. Use Fire-Safe Containers
- Charge and store batteries in a fireproof LiPo bag or metal ammo box with ventilation holes. Never charge on combustible surfaces. [1]
3. Keep an Extinguisher Nearby
- If charging near a work area, have a Class D or dry chemical extinguisher on hand and know how to use it in case of a battery fire. [1]
4. Keep Batteries Away from Children and Pets
- Even small batteries can be dangerous if punctured, chewed, or swallowed. Store them out of reach in clearly labeled containers. [1]
BATTERY SAFETY REMINDER
Battery power comes with responsibility. Improper storage or charging of lithium batteries can lead to fires, explosions, or toxic fumes. Handle with care, follow manufacturer guidelines, and always store them with fire safety in mind.
