Maintenance Tips for Cylindrical Lithium Batteries

Here are recommended maintenance guidelines for cylindrical lithium batteries, written in English:

Maintenance Tips for Cylindrical Lithium Batteries

1. Avoid Extreme Temperatures
   Store and use the battery in environments between 0°C and 40°C (32°F–104°F). Extreme heat accelerates aging, while freezing temperatures can reduce performance and cause internal damage.

2. Charge Properly

• Use a compatible charger and avoid fast-charging too often, as it increases heat and long-term wear.

• Disconnect the battery once fully charged to prevent overcharging.

• Maintain the battery between 20% and 80% charge for optimal longevity.

3. Prevent Deep Discharge
   Do not let the battery drop below 10% or stay completely drained for a long period. Deep discharge can cause irreversible damage.

4. Store Correctly
   If not used for an extended period:

• Store at around 40–60% charge.

• Keep in a cool, dry place, away from direct sunlight.

• Check and recharge every 3–6 months to maintain health.

5. Avoid Physical Damage
   Do not crush, puncture, or drop the battery. Any deformation can compromise internal safety mechanisms.

6. Keep Contacts Clean
   Periodically wipe battery terminals with a dry cloth to ensure stable electrical contact.

7. Use Within Recommended Limits
   Do not exceed the battery’s rated current, voltage, or load. Operating beyond specification can cause overheating or shortened lifespan.

8. Monitor Battery Health
   Signs such as swelling, unusual heat, or reduced capacity indicate the battery should be replaced immediately.
