Okay so after 24 hours of rest inside my house I got a series reading of 12.64v.
12.7v is full correct?
What should my new Costco Interstate's be reading so I know the difference between a bad charger and a bad newly manufactured 6-month-old battery?
I just put them in the garage and clipped the shop charger to them.
Charging now at 14.78v. All six cells are bubbling while charging, the trailing battery in the series was doing so a bit more so than the leading one. ...not sure if that matters.
To confirm what everyone is saying (and as previously posted) my WFCO converter was charging at 13.67v yesterday. Then I saw THIS sticker on the power center
We dry camped perhaps 10-12 nights last year on weekender trips.
Four or five trips ranging 4-7 nights at family resorts & screaming kids parks with electric.
Should I worry about the 3 stage WFCO when it's less than a dozen nights without shore power per year?
I am thinking before I spend $200 on a good 4 stage converter I will just throw the shop charger into the pickup bed and charge the batteries that way.
If I do should I flip the battery disconnect on the TT so 14.7v volts dont harm my trailer?
12.65V is full charge on most all flooded cell batteries. Trojans are 12.72V. Specific gravity is a better indication than OCV.
