I have searced the archives. I know this topic has been discussed before but I can't find the answer. My 2002 360 wouldn't start today. There is enough power in the battery to run all the lights, radio, dash lights, guages etc. but not enough power to turn the motor over. I called the dealer and of course the service dept. is closed on Saturday but the service manager did pick up the phone. He told me to use the Battery Tender Plus to recharge the battery. According to the instruction manual it could take "days" to charge the battery. The service manager told me NOT to jump start the car under any circumstances. So if the Battery Tender doesn't do the job the car will have to be towed in on Monday. My questions are: Has anyone had any success with these type of chargers actually recharging a battery enough to start the car? Or should I go to the local auto store and buy one of the quick charge devices that plug into the lighter? Could these devices cause any damage to the electrical system? I'm trying to avoid towing the car into the shop because it's a hassel.
