CPY

​Certifications:​​ All batteries comply with UL 1642 (cell safety)1, UN38.3 (transportation)1, and RoHS standards. Full documentation (MSDS, UN labels) is provided for logistics.

​Prohibited Actions:​Never immerse batteries in water or expose to fire.Avoid reverse polarity (incorrect +/- connections)​

Charge Management:​Maintain SOC (State of Charge) between 20%-80% for daily use. Fully discharge to 15%-20% monthly to calibrate SOC accuracy35​Prioritize slow charging; limit fast charging to ≤2 sessions/week

​Temperature Control:​Charging:​​ Avoid charging in direct sunlight or above 40°C (104°F) High temperatures degrade cell chemistry
​Storage:​​ Keep in a dry, cool environment (15-25°C / 59-77°F)

​Long-Term Storage:​​

Maintain SOC at 40%-60% if unused for >7 days35. Recharge to 60% every 3 months to prevent deep discharge35

​Transportation:​​ Use original anti-shock packaging and reduce SOC to ≤30% before shipping

Abnormal Conditions:​​ If you notice swelling, leakage, or overheating:

Fire Response:​​ Use Class D fire extinguishers (dry powder) for lithium battery fires
