Warnings & Precautions
Charging
-
Use a Dedicated Charger: ALWAYS use a Li-ion/Li-Po specific charger designed for the correct CC/CV method and the precise charge voltage.
-
Never Overcharge: Do not leave the battery connected to the charger indefinitely after it is fully charged.
-
Charge in a Safe Area: Always charge on a non-flammable surface in a well-ventilated area. Never charge unattended or while sleeping.
-
Respect Temperature Limits: Charge only within the specified temperature range (0°C to 45°C). Do not charge below 0°C.
Discharging
-
Prevent Over-Discharge: Never discharge the cell below the 3.0V cut-off voltage. Continuous over-discharge will cause permanent damage and is a safety hazard .
-
Avoid Extreme Loads: Do not exceed the specified maximum continuous discharge current.
-
Temperature Management: If the battery becomes excessively hot (e.g., >60°C) during use, stop the operation immediately and allow it to cool down in a safe place.
Storage
-
Optimal Storage State: For long-term storage (>1 month), condition the battery to a 30%-50% state of charge (approx. 3.7V - 3.8V) .
-
Storage Environment: Store in a cool, dry place away from direct sunlight, heat sources, and flammable materials.
-
Transport Precautions: Protect terminals from short circuits by covering them with insulating tape or using individual plastic storage bags.
