Highlander has been sitting a few days in the garage in Northern VA. Its been cold but not too bad. Went to start it this morning..gauges going crazy and heard a winding noise. No starter contact with flywheel. Battery terminals looked ok so I put the charger on it for 10 minutes. Started right up. Was going to replace the battery (original) in May or so but decided to replace it today. Went to COSTCO for their Interstate 24F 700 CCA battery $89.99 plus tax. Of course there is a refundable $15 core charge. Changed the battery in the parking lot ... 5 minute change out.. 1st start... engine stalles ... 2nd start ..engine starts, no issues. Runs good. Radio reset to 89 or so .... but saved stations were saved. Navigation saved addresses were all there. Probably could have gotten a little more time on the origonal battery, but 4 months shy of 5 years is probably about average.
