RV Battery Care

  • Visually inspect the battery regularly (once per month).
  • Clean battery terminals occasionally with baking soda and water solution or a commercially available battery terminal cleaner. Make this part of your routine maintenance schedule. Keeping battery terminals clean will extend the battery life.
  • Ensure terminal connections are tight and do not loosen over time. This will help prevent corrosion and unwanted discharge.
  • Coat terminal connections with grease or other lubricant to prevent unwanted discharge.
  • Ensure the battery is brought up to full charge when not being used. Batteries which fully discharge will have a shorter life and degraded performance.
  • Store battery in cool, dry place (68°F/20°C).
  • Recycle batteries, do not dispose.
