I've had problems with the battery since a phone car kit was removed from my Boxster recently. Problem seems to occur when I leave the CD changer door open for long periods but I'm not sure if this is the root cause
So I need to diagnose the leak. But my first problem is the procedure to recharge the battery. Last time it went flat the alarm went off when I opened the doors and I couldnt stop it
Anyone got any guidance on steps to getting out and recharging the battery
Thanks
