What I meant by 3 hours is that the car has not been driven since the new brushes (indicating that tey could not need replacement again). I drove it all of 5 miles since the new brushes (car has been driven LESS than 200 miles in the last year). The battery however is brand new and is the second new battery for the car in a year. I thought the battery I bought last year may have gone bad, so I got a new one last week.
