Following the suggestion here that the charging voltage for Circuit C
was too high

I checked with an accurate meter. The voltage was 13.86V. That accords
with the very low residual charge rate. As I suspected, the van's
voltmeter is reading a bit high.

That's still high for a float charge. Should be more like 13v.

But the charge rate is 0.01A

That suggests the battery is fully charged and the current is there to
offset the self-discharge current.
