To determine the type of battery you need for your RV, there are a few key factors to consider:
1. Battery Purpose
RVs typically require two different types of batteries - a starter battery and deep cycle battery(ies).
- Starter Battery: This is used specifically to start the engine of your RV or tow vehicle. It provides a high burst of power for a short time to crank the engine.
- Deep Cycle Battery: These are designed to provide steady power over an extended period for things like lights, appliances, electronics etc. when dry camping or boondocking.
2. Battery Type
The main types of deep cycle batteries for RVs are:
- Flooded Lead-Acid: Require periodic maintenance to check water levels. More affordable upfront.
- Absorbed Glass Mat (AGM): Sealed, maintenance-free design. More expensive but better longevity.
- Lithium: Lithium-ion batteries are lightweight and can handle deeper discharge cycles but are the most expensive option.
3. Battery Bank Size
The number of batteries you'll need depends on your power usage and how long you need to dry camp. Most RVs have a battery bank consisting of 2-6 deep cycle batteries wired together.
To determine the ideal battery(ies) for your RV's needs, consider:
- How often and for how long you dry camp
- Your power consumption from appliances, electronics, etc.
- Battery reserve capacity/amp-hour rating to meet your runtime requirements
Consulting with an RV dealer or battery expert can help analyze your specific power needs and recommend the most suitable battery type, size, and battery bank setup for your RV lifestyle.
