-
Never charge at currents exceeding 1C (4500mA) without proper -ΔV detection.
-
Avoid charging at temperatures below 0°C or above 45°C.
-
Ensure proper ventilation during charging.
Discharging
- Avoid deep discharge below 1.0V per cell.
-
Do not short-circuit terminals.
-
Monitor battery temperature during high-rate discharge.
-
Replace batteries when capacity drops below 80% of original.
Storage & Handling
- Store at room temperature (20°C) with 40-50% charge state
-
Avoid storage in fully charged or fully discharged state
-
Keep away from direct sunlight and heat sources
-
Store in dry conditions to prevent terminal corrosion
-
Implement regular testing for emergency applications
