Van has been sitting in a field all winter, no hookup.

Looking ok?

Acceptable, given the winter temperatures you are averaging a 6ah self discharge. If was me, for long periods of storage, I would drop the float to 13.2v and reduce the absorption time under a hr if possible. Since you start evrey morning with full battery voltage, excessive bulk and high float in storage it just accelerates unnecessary corrosion.

Many thanks for the reply as I am not a techie, I have no understanding of your reply my fault not yours, but I do thank you..

The battery hasn’t gone below fully charged so looks ok to me

Reminds me of the time I practiced my schoolboy French in a Bakery Boulangerie last time we were in France, couldn't understand the reply!

I find the same when I try English south of Watford
