The above suggests the batteries were at 13V in the morning with no source of external charge. Unlikely, and that doesn't tell us anything about the batteries real state or their ability to support a somewhat heavy load.
I'd want to know the age of the batteries and their condition via SG and possibly a load test, not voltage.
