Hi all ive not been using my car for about 4 months thought i would go today and give it a turn over the battery has been on a trickle charger and it read on the charger it was in good health but it wouldnt turn it over so presume this will be a new battery. As it is a racing battery do i need the same or is there an alternative for my car ? Also would like to know whats the best thing to do about the fuel in the car when leaving it for so many months, full tank, empty tank use a additive not sure.
