Battery Maintenance

Why is battery maintenance important?

Proper battery maintenance is crucial for an RV because the battery powers essential systems when you're not connected to shore power. From lights and water pumps to refrigerators and furnace fans, a healthy battery ensures comfort and functionality on the road or at a campsite. Without regular maintenance—like checking fluid levels, cleaning terminals, and ensuring a full charge—batteries can degrade quickly, leaving you without power when you need it most. Maintaining your RV battery not only extends its lifespan but also helps prevent unexpected breakdowns and costly replacements.

• If you need assistance in maintaining your batteries or have more in-depth questions reach out to your local RV Dealership Service or Parts Department for more details.

Best ways to maintain your RV batteries

• Check Water Levels (for lead-acid batteries): Regularly inspect and top off with distilled water to keep the electrolyte levels above the plates.

• Clean Battery Terminals: Remove corrosion with a mixture of baking soda and water, and apply terminal protectant to prevent buildup.

• Fully Charge Regularly: Keep batteries charged to avoid sulfation, especially during storage or long periods of non-use.

• Avoid Overcharging: Use a smart charger or charge controller to prevent overheating and overcharging, which can shorten battery life.

• Disconnect When Not in Use: Use a battery disconnect switch to prevent phantom power drains from RV electronics when stored.

• Store in a Cool, Dry Place: Heat can reduce battery lifespan, so keep them out of direct sunlight or high-heat environments.

• Use a Battery Monitor: Install a battery monitor to track charge levels, health, and usage patterns more precisely.

• Equalize Periodically (for flooded lead-acid batteries): Perform an equalizing charge to balance the cells and prevent stratification.

• Inspect for Damage: Regularly check for bulges, cracks, or leaks in the battery casing.

• Know Your Battery Type: Maintain AGM, lithium, and flooded lead-acid batteries according to their specific care needs—they’re not one-size-fits-all.
