Outline three cure and maintenance practices observed when handling a secondary cell?

1. Regular charging: Secondary cells should be charged regularly to maintain their capacity and prevent them from becoming completely discharged. Over-discharging a secondary cell can lead to irreversible damage and reduce its lifespan.

2. Proper storage: Secondary cells should be stored in a cool, dry place when not in use. Extreme temperatures can affect the performance and longevity of the cell. It is also important to store secondary cells in a safe and secure manner to prevent any damage or accidents.

3. Avoiding overcharging: Overcharging a secondary cell can lead to overheating, swelling, and potentially cause the cell to explode. It is important to monitor the charging process and disconnect the cell once it is fully charged to prevent any damage. Using a charger with overcharge protection can also help prevent overcharging.
