Well, I'm a bit ashamed to have to admit this, but I assumed that with a new camper, the batteries would be fully charged. Not only were they not charged (6.3v) but I found out that the batteries were severely lacking battery fluid! One took 16oz. of distilled water, and the other took 20oz! I called my local battery supplier (ironically one that sells this same brand of batteries), and they told me the only way batteries could be this low in fluid is if they were overcharged and boiled dry, or they were very old. They then advised me how to find out when they were made. Their mfgr. date was Feb. 2016!
No wonder the poor things couldn't raise the camper!!!!!
Boy, I'm learning SO much having this new camper!!!!
