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 does it mean when your RV battery goes dead?
The fact that the lights got brighter when you started the engine is an indication that the batteries are indeed very low, if not completely dead. The engine alternator was simply providing the DC voltage while the engine was running.
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.

Why do car batteries die all the time?
Corrosion Can Cause Battery Death Battery acid is corrosive. That might sound obvious, but one of the other reasons why car batteries repeatedly die is due to corrosion at the connections. Check under your hood.
What happens to the battery when you charge your phone overnight?
During overnight charging, your phone constantly uses battery to stay functional, much like all things living; and when consumption happens, recharging happens. And this opens up to a hell of short-lived battery for whoever couldn’t bear to replace their phones every year or two.
Is it normal for a car battery to drain after 30min?
Ok, so that is definitely a ‘normal’ draw. 180mA is a little steep for 30min IMHO but shouldn’t flatten any healthy car battery. So I think you can rule out parasitic drain by the car electrics.

Why is it bad to charge phone at half charge?
The worst of all, the buildup blooms like wildflowers after rainy days at higher battery levels and temperatures. Certainly, maintaining a high battery level longer will degrade the battery faster. And this is even more harmful than cycling a battery. Which is why many, including Apple, recommend storing your battery at half charge …
