What could be causing my rv battery to drain.

My rv batter keeps draining.


Answer by  noonespecial (235)

Leaving the RV on, or sometimes just leaving the batteries in, can cause them to drain faster. Alkaline batteries also don't last as long in electronics as rechargable batteries.

The battery may have a dead cell. Even new batteries are inadvertently sold with a dead cell. Replace the battery first then check the rv alternator. Either the battery or the alternator is bad.

Either an excessive load (too much electrical stuff turned on), or a failed generator. You might consider checking the alternator, or installing solar panels for when the RV isn't running.

Most likely cause is 12v drain from stuff that uses very minor amounts of power, or a dead short somewhere. Try switching 12v power to rig off (switch should be inside by outside door). Batteries drain a bit regardless, so if rig is parked for long periods, remove battery and have recharged before using.
