Hey members,
I've been full solar offgrid for nearly 18 months in a 420sqft cabin/tinyhome.
My battery bank is 4 deep cycles wired in parallel. Here is a link to the batteries I'm using (http://www.walmart.ca/en/ip/1643906-.../6000016951063) they were $100 at Walmart and were basically all I could afford when I began my offgrid adventure.
Recently it appears as though my battery bank is acting strange. My controllers and voltmeter both report to me that my batteries are reaching 12.7v (full) by the time the sun goes down and within a few hours of no/slight use my batteries seem to go down to 11.9v. I checked the water levels today, many seemed low. I used up nearly 1 gallon of distilled water to top them back up. It was the first time I ever checked them.
So Ive been reading that because my water levels were low and we had sub zero celcius temperatures recently that maybe they have been damaged or sulphated? Maybe these are just **** batteries to begin with? Any ideas about whats going on and what I can do to fix them?
