New 6 volt batteries, problem?
Hey everyone,
Hoping for some input on the new battery situation. We have a 2015 class C, about one year old next month. I’ve replaced the converter in my WFCO 8955 with a Progressive Dynamics 9270 already.
In the last week I purchased two new 6 volt US Battery 2200’s to replace the factory 12v’s house batteries that came with it. Date stamp on the new batteries was Feb (IIRC) 2016. When I installed them, voltage on each was around 6.2, and 12.4 when wired up. I figured no problem, and left the RV connected to shore power for about 3 days before our trip this weekend.
Upon unplugging and driving to our campsite today (less than 20 miles), my volt meter shows still 12.4 on the batteries. Any idea what gives? Shouldn’t I be seeing 12.7+ on a full charge still with two 6v batts in series?
I did notice the other day that the electrolyte level on the new batteries was not close to the bottom of the fill neck, but about halfway down to the plates. I estimate 1/2” above the plates, and 1/2” below the fill neck. I did not get a chance to top them off, but assumed they would be fine for the moment. I assume this should be the typical 1/8” or so just below the fill neck on these as well? The RV was level while charging, and is level at the campsite.
I did not check voltage after unplugging from shore power, before leaving. I only did prior to unplugging and the PD9270 was in storage mode at the time, it was around 13.2v if I recall, but I know it charged these batteries in all stages. The converter had no issues charging the previous 12v batteries.
Had to run back to work for the rest of the day but will be back this evening to see how they are doing, with the family using them. I don’t have a hydrometer but I think that may be next on my list.
Thank you for any input!
