Re: [VAL] Battery Charging or lack thereof

[William Kerfoot <wkerfoot@xxxxxxxxxxxx>]

Blair,

I have two group 27 RV deep cycle batteries, one about three years old 
and one a year old.  I pulled both of them out tonight, they are not 
dry, the water is above the plates.  I have never had to add water in 
the 2 1/2 years that we have had the trailer.  I don't think that the 
problem is overcharging, I think that the problem is not charging.  At 
Uwe's suggestion, in a phone conversation with him, I am charging both 
batteries, now at 12.5V, I will then reinstall them, check the voltage, 
the plug in and recheck the voltage.  Uwe thinks that the voltage should 
be 14+ with the trailer plugged in, if not then the univolt is not 
working on charge circuit.  Any comments?

Remember, I have a 1979 trailer.  Were there changes and improvements to 
the univolts from the time they were introduced in the 60's to the age 
of my trailer and beyond?  Also, when was the univolt discontinued and 
what replaced it?

I want to know the reason for the lack of charging before I start 
replacing parts just to replace parts.

Inept in electrical, ept in mechanical.
