If you own an RV, you're likely familiar with the frustration of a dead or nearly dead battery. This is a common issue faced by many RV owners, often due to parasitic loads from various electrical components like CO and propane detectors, stereos, and LED lights. These components can continue to drain power, even when the OEM battery switch is off.
Understanding Parasitic Drain in RV Batteries
It's surprising how these drains stay active in most RVs, regardless of the battery switch position. Some components, such as stereo systems and detectors, remain on to maintain their functionality. This constant drain can lead to severe battery depletion, especially during storage.
The Consequences of Neglecting Battery Maintenance
Many RV owners store their vehicles with batteries inside, leading to significant discharge. In extreme cases, this can result in batteries freezing and cracking, causing leaks and necessitating replacements.
Effective Solutions for Battery Maintenance and Storage
Charging During Storage: When storing your RV, it's crucial to keep the batteries charged. This can be done through shore power or a solar charging system. If opting for solar, ensure it's powerful enough to counteract the parasitic loads.
Regular Maintenance: Keep the battery tops clean and the cells filled with distilled water. Avoid mineral-charged water as it can damage the batteries over time.
Alternative Storage Solutions: For long-term non-use, consider removing the batteries and storing them in a controlled environment, ideally on a wooden or rubber shelf above the floor.
