2. Keep Terminals Clean:
   Keeping terminals clean involves removing corrosion and dirt that can accumulate on battery posts and cables. This corrosion can hinder the battery’s performance. A mixture of baking soda and water can effectively clean terminals. A well-maintained terminal connection can improve conductivity and prolong battery life by up to 30%, as noted by the Battery Council International.

3. Store the Battery Properly:
   Storing the battery properly means placing it in a cool, dry environment when not in use. A temperature range of 32°F to 80°F is ideal. Storing in extreme temperatures can cause battery degradation. According to the National Renewable Energy Laboratory, batteries stored in cooler conditions retain charge better than those in heat.

4. Avoid Extreme Temperatures:
   Avoiding extreme temperatures refers to keeping the battery out of prolonged heat and freezing conditions. High temperatures can accelerate chemical reactions in the battery, leading to faster wear. Conversely, cold temperatures can inhibit performance. Research by the California Energy Commission shows that batteries exposed to excessive heat can lose up to 50% of their capacity over time.

5. Use the Battery Regularly:
   Using the battery regularly means ensuring it is charged and discharged periodically. Infrequent use can lead to inactivity, which can cause sulfation. A report from the Electric Power Research Institute suggests that regular cycling helps maintain the battery’s active material and keeps it healthy, thus extending its life.

6. Inspect the Battery Regularly:
   Inspecting the battery regularly involves checking for damage, leaks, or swelling. Visual inspections can reveal issues before they become serious problems. Regular checks can prevent failures in the field, which can be costly. The American National Standards Institute recommends a routine inspection at least every few months to ensure optimal battery health.
