Warnings & Precautions
Charging
- Use only NiCd-specific chargers with proper voltage/current regulation.
-
Never exceed maximum charge voltage of 15.0V.
-
Avoid charging at temperatures below 0°C or above 45°C.
-
Ensure proper ventilation during charging.
Discharging
- Avoid deep discharge below 10.0V (pack voltage).
-
Do not short-circuit terminals.
-
Monitor battery temperature during high-rate discharge.
-
Replace battery 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 rotation for backup applications.
