   If not in use for extended periods, remove batteries or store them at around 50% charge.

4. Avoid Extreme Temperatures
   Both heat and cold degrade battery performance over time.

5. Regularly Maintain Contacts
   Clean terminals periodically to prevent corrosion which can reduce efficiency.

6. Use Correct Chargers
   Always use chargers recommended by manufacturers to avoid damaging cells.
