What causes an RV battery to 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 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 happens when you use a lead battery?
While each draws a small charge, they can completely kill a battery when combined. Picking up a battery disconnect switch to stop chronic drain for good. Whenever you use a lead battery, small crystals of sulfuric acid start forming on the metal plates inside. The crystals disappear when the battery’s charged.
What causes a microwave battery to go dead?
If the converter charging module (or the breaker for the converter), is turned off, or if you have some type of battery disconnect solenoid engaged, the batteries will not be able to receive a charge. Your microwave, by the way, is powered by 120-volts AC only, which is why the clock still works.
What to do if your slide out camper battery is dead?

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.
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.
Why does my RV battery keep dying at low charge?
But when a battery stays at a low charge (below 12.5 volts) for a long time, the crystals get too large to break down and the battery is busted–who knew? Charge your battery fully and frequently, and never let it drain below 50%. Your RV battery is 64% water.
