I have not needed one yet, knock wood. Just keep accessories turned off and you should be fine for the 15-20 minute flash. Also wise to make sure the battery is fully charged by taking s good drive suitable to recharge the battery. Maybe 30 minutes or longer depending on how long the car has been sitting around.
