When storing your RV for an extended period, it's generally recommended to turn off the battery disconnect switch. This helps to prevent any parasitic loads from draining the battery. Here's a breakdown of the reasons:
- Parasitic Drains: Even when you think everything in your RV is off, some devices might still draw a tiny amount of power. Examples include the propane leak detector, radio memory, or any other small electrical components that stay on. Over time, these drains can deplete the battery.
- Battery Lifespan: Constantly exposing the battery to small drains can reduce its lifespan.
- Safety: Disconnecting the battery minimizes the risk of any accidental short-circuits or other electrical issues that can arise when an RV is in storage.
However, there are some things to consider:
- Battery Maintenance: Lead-acid batteries (like the ones commonly used in RVs) naturally self-discharge over time, even if they are disconnected. If you're storing the RV for a long time, you'll want to ensure the batteries remain charged. A depleted battery can freeze in cold temperatures, leading to potential damage.
- Charging Solutions: If you have access to power where the RV is stored, consider using a trickle charger or a battery maintainer. This will keep the battery topped up without overcharging it.
- Check Fluid Levels: If you have a flooded lead-acid battery, you'll want to check the fluid levels periodically and top up with distilled water if needed.
- Remove the Battery: If you're storing the RV in extremely cold conditions for an extended period, consider removing the battery and storing it in a warmer, dry location. This can help extend the battery's life.
In conclusion, if you're putting your RV in storage, it's a good practice to turn off the battery disconnect switch. Just make sure you have a plan for maintaining the battery's charge during storage.
