so i want to put another battary in my car to run thongs like my accessoriey extra stuff i put in,such as neons/fog lights/subs+amp/ect. i started to think about it and i thought it seemed like a good idea til i though of posible problems. The only thing i could think of as a proble would be how would i be able to keep it charged? I wouldnt wanna hook it up to the alternator with the battery for the car itself becuase i dont know how much that can hold and i really dont wanna pucs too much power on the cars electronics. so could there be another way such as somehow install another alternator or would i have to sit with a car charger every day or so to keep it charged?
