Hi all,
 
	 
 
	Currently in the process of buying a new battery for my car, I'm unsure of the cold cranking amps for the car + the hourly amp rate.
 
	I've got an aftermarket head unit in the car.
 
	The few battery sites I've tried the terminals are the wrong way round and I don't want to stretch the cables too much.
 
	When I popped into Halfords they weren't much help either.
 
	 
 
	Thanks!
