To minimize risks:

• Follow Manufacturer Guidelines: Adhere to usage and charging instructions.
• Temperature Awareness: Avoid extreme temperature exposure.
• Use Compatible Chargers: Specifically designed for lithium batteries.
• Regular Inspection: Check for damage or irregularities.
• Appropriate Storage: Use proper containers when not in use.

If a battery seems unsafe:

1. Stop Use: Immediately discontinue usage.
2. Safe Removal: Remove from device or charger carefully.
3. Safe Disposal: Place in fireproof container away from flammable materials.

Lastly, Proper Disposal: Recycle old or damaged batteries through retailer recycling programs for environmental and personal safety.

Understanding and addressing potential risks associated with lithium batteries are crucial steps in ensuring their safe usage and handling.

Signs that your lithium battery may be unsafe

1. Bulging or Swelling:
   • Internal Damage: Indicates potential issues and should not be overlooked.
2. Excessive Heat:
   • Abnormal Temperatures: While some heat is normal, extreme temperatures signal underlying problems in cells or circuitry.
3. Decreased Performance:
   • Reduced Capacity: Quick depletion or decreased charge-holding may signal a failing battery.
4. Leakage or Stains:
   • Electrolyte Leakage: Any leaks or stains on the casing can be highly dangerous due to electrolyte leakage.
5. Unusual Odors:
   • Strong, Uncommon Smells: Rotten egg-like odor might indicate internal gas release, needing immediate attention.

These signs aren’t definitive proof of danger but serve as critical warnings requiring prompt investigation. If you notice any, stop using the battery and seek professional guidance on handling it safely.

Proper care and maintenance for lithium batteries

1. Storage Conditions:
   • Temperature Control: Store in a cool, dry place away from direct sunlight or extreme temperatures.
   • Avoid Extremes: Keep batteries away from excessively hot or cold environments.
2. Charging Practices:
   • Avoid Over/Undercharging: Unplug devices once fully charged; don’t let batteries completely drain often.
   • Preserve Capacity: Prevents damage and maintains battery life.
3. Regular Inspection:
   • Check for Damage: Watch for swelling, leaks, or unusual odors as potential signs of trouble.
   • Immediate Action: Discontinue use and seek professional help if any issues arise.
4. Cleaning Contacts:
   • Maintain Connections: Regularly clean device and battery contacts with a soft cloth to ensure proper connectivity.
5. Safe Transportation:
   • Protective Measures: Use original packaging or appropriate materials during travel to prevent accidental short-circuits.

Following these care practices will extend the lifespan of your lithium batteries while ensuring safer and more efficient usage.

Steps to take if you suspect your lithium battery is unsafe

1. Remove the Battery:
   • Immediate Removal: Take it out from the device to prevent further harm.
   • Handle Carefully: Avoid damaging or puncturing the battery.
2. Inspect for Damage:
   • Physical Examination: Check for swelling, leaks, or unusual odors as signs of trouble.
   • Confirmation: These indicators could signal battery issues.
3. Cease Use and Disposal:
   • Stop Use: Avoid using or charging the battery if confirmed unsafe.
   • Safe Disposal: Follow local regulations for hazardous waste disposal or designated drop-off locations.
4. Manufacturer Contact:
   • Seek Guidance: Contact the device or battery manufacturer for advice on handling unsafe batteries.

Always prioritize safety when dealing with potentially unsafe lithium batteries. Following these steps can help reduce risks and ensure safety for you and those around you.
