Maintenance
Proper maintenance ensures longevity and optimal performance of your battery:
- Cleaning: Keep the battery terminals clean and free of debris. Use a clean, dry cloth to wipe the battery. Do not use solvents or harsh chemicals.
- Storage: For long-term storage, store the battery in a cool, dry place, away from moisture and direct sunlight. It is recommended to store NiCd batteries fully discharged to prevent memory effect, though some modern NiCd batteries are less susceptible.
- Charging cycles: NiCd batteries benefit from full discharge and recharge cycles to maintain capacity and prevent "memory effect."
- Avoid extreme temperatures: Do not store or charge the battery in extreme hot or cold conditions, as this can reduce battery life and performance.
