I have a 2011 Honda Accord coupe battery keeps going dead, replaced battery alternator was tested by Honda...still having the same
My car has 103146 miles.
My car has an automatic transmission.
If the battery is new (or has passed a load test) and charging system output has been measured and is within specifications, the only reason a battery will discharge is if the car sits for a long period of time (batteries will self-discharge even if not used) or if there are parasitic (excess) loads on any of the car’s electrical circuits. If there is excess current flow that is slowly draining the battery, a Mechanic would use an ammeter to test all of the various circuits until the faulty circuit is found. Then that circuit is traced to find the fault and repair it.
