new battery dead while pluged in
My camper (keystone VR1) stays plugged in on a shore power 30amp hooked to my house. i went the other day and noticed that the battery was low, so after checking all the fuses, i removed it and purch...

If the converter has no 13-14vdc output.
(If any of this in unfamiliar to you, get a qualified electrician!)
Check:
1. In the distribution panel with cover removed, check the 120vac circuit breaker feeding the converter. (Check for 120vac on the output of the turned on breaker. If not, Bad breaker. Also, look for a broken/loose/burned wire on the breaker or on the neutral bar. I've seen plenty burned/broken wires from loose terminations.)
2. Disconnect the battery. Check for 13vdc on the output side of the converter. (Check it at the Main 12vdc fuse in the distribution panel. No voltage on the input side of the fuse(with 120v feeding the converter) means bad converter and replace with a better multi-stage unit. If voltage is present on the input side of the fuse but not on the output side, then replace fuse.)
Here is a Meter you can plug into a 12v outlet and keep an eye on the batteries when everything is working.
Letting the battery voltage drop below 12.00Vdc(50% charge state) will shorten the life of the battery.
Here is a 12v battery voltage State of Charge chart:
12.6+ = 100%
12.50 = 90%
12.42 = 80%
12.32 = 70%
12.20 = 60%
12.06 = 50%
11.90 = 40%
11.75 = 30%
11.58 = 20%
11.31 = 10%
10.5 = 0%
