One of my neighbors has a VW Lupo 1.2 or 1.4 her battery was flat so i jump started her car and she said i could go for a drive to re-charge it, i drove it for about 35 minutes and did about 40 Km ( 25 miles ) , on the highway with the engine at about 4k rpm, Would that be enough to re charge it to some extent so it'll start next time?
