I keep thinking there must be a better way to check battery SG. A good hydrometer is almost ideal, the issue I keep having is the top of the float wanting to rest on the glass making repeatable measurements problematic.
I have to agree with you on this ktmrfs. I tried a few times over the years to use my hydrometer but the float always sticks to the tube. Now I just take a voltage measurement and see if I'm around 12.7 when full.
After a few years goes by and it seems that the batteries are draining faster than normal when dry camping I just replace them. Yes I could spend time maintaining my batteries and extend their life from 5 years to 10. Maybe when I retire I'll pay more attention to my batteries. But in my current life usually I have too much going on to have time to worry about my weekender trailer batteries.
