There are only a few things more frustrating than gearing up for a road trip only to find your RV battery completely dead. You had everything packed, the route planned, and snacks ready. But without power, comes no journey at all.
Whether you’re storing your RV for a season or just a few weeks, knowing how to keep your RV battery charged in storage is essential. Proper maintenance not only saves you from inconvenient surprises but also extends your battery’s life and protects one of your RV’s most vital components.
Here’s how you can do it right.
Why RV Batteries Die in Storage
Even when your RV is sitting idle, certain systems continue to draw power. These are called parasitic loads, and they include things like:
- CO and propane detectors
- Stereo memory settings
- Clocks
- Control boards in appliances
Over time, these small power drains can fully deplete your battery, especially if your RV is stored outdoors or in a location without easy access to electricity.
And let’s not start about the weather. Cold temperatures can freeze a depleted battery, while extreme heat accelerates internal chemical breakdown, leading to reduced battery capacity.
Tips on How to Keep RV Battery Charged in Storage
To keep your RV battery healthy and ready to go, follow these smart storage practices:
1. Disconnect the Battery for Long-Term Storage
If your RV will be unused for more than a few weeks, disconnecting the battery is a simple first step. This prevents parasitic drains and slows down the discharge rate. Just remember to store the battery in a cool, dry place.
2. Use a Trickle Charger or Battery Maintainer
One of the most effective ways to maintain charge is with a trickle charger or battery maintainer. These devices supply a small, steady current that keeps the battery at an optimal level without overcharging. If your RV is parked near an outlet, it’s an easy solution.
3. Try a Solar Battery Charger
If shore power isn’t an option, solar chargers can be a game-changer. A small panel mounted on the roof or dashboard can deliver just enough power to maintain charge, particularly in sunny climates. Just be sure to use a solar charge controller to prevent overcharging.
4. Remove and Store the Battery in a Temperature-Controlled Space
In extreme cold or heat, it’s better to remove the battery and store it somewhere like a garage or climate controlled storage unit. This reduces exposure to damaging temperatures and slows the rate of self-discharge.
5. Inspect and Maintain Battery Health Regularly
Even in storage, your battery needs periodic attention. Check voltage every 3–4 weeks. If it drops below 12.4 volts, it’s time to recharge. Clean terminals and apply dielectric grease to prevent corrosion.
The Role of Storage Facilities in Battery Maintenance
Where you store your RV plays a major role in battery care. At Straub Road RV and Self Storage, we offer both old-fashioned non-climate-controlled and climate-controlled RV storage options, which help regulate temperature and reduce the stress on your RV’s systems—including the battery.
By choosing the right storage conditions, you reduce the likelihood of extreme weather affecting battery performance. Covered spaces help shield your RV from direct sunlight, while enclosed units offer complete protection from heat, cold, and moisture. And if you follow the tips above, you can also opt for the pocket-friendly, non-climate-controlled option.
Additional Tips for Long-Term RV Storage
In addition to battery care, consider these quick maintenance checks:
- Turn off the main power switch
- Check and refill battery water levels if applicable
- Use a multimeter to monitor battery charge levels
- Label wires if disconnecting multiple batteries for easy reinstallation
- Keep a record of maintenance dates to avoid guesswork
These small steps go a long way in ensuring your RV is road-ready when you need it most.
