- Avoid Over-Discharge: Do not leave the battery completely discharged for extended periods, as this can reduce its lifespan.

- Storage: If storing the battery for an extended period, charge it to about 50% capacity and store it in a cool, dry place. Recharge it every few months to prevent deep discharge.
