Battery ?
 

Hi guys I have naught a v60 1.6d rdesign 2012 I've had for two months ,since ive had it the stop start hasn't worked so I looked at the my car screen whit says it's disabled as battery is charging , so I got a set of testers from my work .car not running read 12.4v car running read 15.3 but the tester also indicated the battery was knackered. Could the regulator on the alternator be faulty as I think that reading is high . I did take pics and video :speechless-
