Why does my RV battery go dead?

Why does my RV battery go dead?

In your RV it’s possible for these parasitic loads to drain the battery when you don’t use or charge the battery for long periods of time. At this rate it won’t take long to completely discharge the battery, and you guessed it if the battery is not recharged sulfation starts forming and the battery will die.

What to do if your battery goes dead when plugged in?

If the voltage does not go up when plugged in, look for a blown fuse in the charge circuit in the converter/charger. Look also for any electronic disconnect switches that totally isolate the battery system.

Why do RV batteries go dead when plugged in?

RV Batteries Go Dead, Even While Plugged Into Shore Power. Regardless of the brand of motorhome, the brand and type of converter/charger installed and whether or not any disconnect devices are employed, it’s obvious the batteries are not receiving a charge while the coach is plugged in to shore power.

What happens to batteries when plugged in to shore power?

When plugged into shore power at the campground, presumably the AC to DC converter will charge the auxiliary battery bank. All the lamps, fans, water pump, etc., still operate on 12-volts DC, just that the DC electricity is provided by the converter instead of the batteries while plugged in.

Why does my coach battery go dead when plugged in?

If you can measure an increase in DC voltage at the battery bank when the coach is plugged in, then the battery charge circuit is at least complete and probably working. If the voltage does not go up when plugged in, look for a blown fuse in the charge circuit in the converter/charger.

What to do if your 50 amp battery is not charging?

If you aren’t familiar with 50 amp service, let us know and we will show you how to safely check it with a multitester. For the time being, just plug a drill or lamp into the standard household plug on the pedestal. 2. The batteries are shot, and will not take or hold a charge.
