Yesterday I was working with batteries and our 6300 or 7300 (1992 era) float is up to 14.1 from 13.2 or so. It is due to the aging batteries I expect making it look like they need more charging but due to their health that can not happen.
This is the reason we start having to add more water and then even more water at them.
The MH has two 12v batteries but the GC has six 6v Trojan T-105's dated Oct 2006 and is on a smart charger and is on a high end tender 24/7 and some have cells that loose water at a faster rate than others.
From my experience neither dumb or smart charges can deal well with batteries at their end of life cycle but both are OK with sound batteries.
Dumb charges I think kill by over charging and smart chargers kill by under charging so one can choose the poison of their choice. The old chargers do equalize by default I have found.
Still my go to charger for the most info is a $30 total manual 6v/6amp, 12v/2 amp and 12v/6amp charger. On a 12 volt battery set on 12/6 amp setting if over night it has not tapered to 1 amp of output I know the battery is nearing the fail point 100% of the time.
RV batteries for the most part take too much abuse to live a long life. As I get older I wish I had not spent so many hours obsessing over RV and other batteries life. Like us they are born dying so use them before you loss them. :)
