I once left my disconnect switch on in my TT when I was storing it, and when I came back a few weeks later, the batteries were down to a couple of lights on the control panel. I disconnected and we p...

I noticed when the electrolyte gets under 60F/15C, the SG goes up. Right now they're around 1.300. Last year at this time the SG was about the same.
And after doing this procedure, on a normal sunny So Cal 70F temp day, will your Specific Gravity show up at around 1.265 pretty consistently plus or minus .005 or less being preferred? Because that's pretty much what I expect out of my batteries.
EDIT: I've also noticed that the battery temp can lag air temp if it's been cold the night before. Ex: the last reading I took (a month ago), it was 55F/13C but battery temp was 47F/8C. It was below freezing the night before. I can raise the battery temp up by opening the compartment door. In the summer, they are usually within a couple degrees.

Does anyone make a digital hydrometer?
