For a battery in active use (being discharged by a load) 11.8V represents about 50% discharged. It's neither good or bad, it just is. If I was 3 days into a 10 day off-grid trip I would call it "bad". If it was like my last trip where I was around 50% after 3 days into a 3 day trip, check the box I made it with lots to spare. Knowing what your capacity is and expected loads is the gauge to use for assigning any particular state of charge as "good" or "bad".Is is bad to be at 11.8 and be using power...???
