Why Is My Battery Draining While Plugged In?

by Phil Borges // in Car

One of the most frustrating situations RV owners face is returning to their parked RV only to find out that their battery is drained even though the RV is plugged into a power source. The issue can be caused by several factors, including faulty wiring, old batteries, or a failing converter.

Why are my RV batteries not charging when plugged into shore power?

If your RV batteries are not charging when connected to shore power, there could be various reasons why. It could be due to a tripped circuit breaker or blown fuse, faulty wiring, a malfunctioning converter, or even an issue with your RV’s battery disconnect switch.

How do I know if my RV converter is charging my battery?

To determine if your RV converter is charging your battery, you can use a multimeter to measure the voltage at the battery terminals. If the voltage reading is between 13.2 and 14.5 volts, then your battery is being charged. You can also check the converter’s LED status lights, which should indicate if the converter is functioning correctly.

Will RV battery charge when plugged in power?

Yes, RV batteries should charge when plugged into power, provided that the power source is functioning correctly, and there are no issues with the RV’s electrical system. However, it’s important to note that a fully depleted battery could take several hours or even days to fully charge, depending on the battery’s capacity and the power source’s output.

In conclusion, RV battery draining while plugged in can be a frustrating experience, but it’s essential to identify the root cause of the issue to prevent it from happening in the future. By understanding how your RV’s electrical system works and regularly maintaining your batteries and converter, you can ensure that your RV is always ready to go when you are.
