Precautions for using lithium battery

Precautions for using lithium battery

Lithium batteries are widely used in various electronic devices due to their high energy 

density and long lifespan. However, improper use can lead to safety hazards such as 

overheating, fires, or even explosions. Taking our 603040 li-po battery as an example here:

Our batteries usually undergo corresponding safety performance tests before leaving the factory. 

Including Short-Circuit Test、HeatingTest、Over Charging Test、Low Pressure Test and so on.

1. Charging Precautions

Use the Correct Charger: Always use the charger designed for your specific battery or device. 

Using an incompatible charger can cause overcharging or overheating.

Avoid Overcharging: Do not leave the battery charging unattended for extended periods. 

Disconnect it once fully charged to prevent stress on the battery.

Charge in a Safe Environment: Charge the battery in a cool, dry place away from flammable materials. 

Avoid charging on beds, sofas, or inside enclosed spaces.

Do Not Charge Damaged Batteries: If the battery is swollen, leaking, or damaged, do not 

charge it—replace it immediately.

2. Temperature Management

Avoid Extreme Temperatures: Do not expose lithium-ion batteries to very high or very low temperatures.

Prevent Overheating: Keep batteries away from direct sunlight, heaters, or other heat sources. 

Overheating can cause thermal runaway (a dangerous chain reaction leading to fire).

Allow Cooling Before Charging: If the battery is hot from use, let it cool down before recharging.

3. Physical Handling & Storage

Avoid Physical Damage: Dropping, puncturing, or crushing the battery can lead to internal short circuits, 

causing fires or explosions.

Store Properly: If storing for a long time, keep the battery at around 40-60% charge in a cool, dry place. 

Avoid storing at full charge or complete discharge.

Keep Away from Metal Objects: Prevent contact with keys, coins, or other conductive materials that 

could short-circuit the terminals.

4. Usage Precautions

Do Not Over-Discharge: Avoid draining the battery completely (below 2.5V per cell), as this can 

permanently damage it.

Follow Manufacturer Guidelines: Adhere to the device’s recommended voltage, current, and usage limits.

Avoid Water Exposure: Lithium-ion batteries should not be submerged in water or exposed to high humidity.

5. Disposal

Do Not Throw in Regular Trash: Lithium-ion batteries should be recycled at designated e-waste facilities.

Tape Terminals Before Disposal: To prevent short circuits during disposal, cover the battery terminals with 

insulating tape.

6. Emergency Measures in Case of Battery Fire

Use a Class D Fire Extinguisher or sand to smother flames. Water is ineffective and can worsen a lithium battery 

fire. Evacuate and Call Emergency Service if the fire is uncontrollable.

By following these precautions, you can maximize the lifespan of your lithium-ion batteries while minimizing safety risks.

 Always prioritize safety when handling and storing these batteries.
