[QUOTE="Thnking, post: 2624706, member: 571105"] A high output alternator has a higher nominal voltage than multiple batteries have. Energy is also created by a mechanical to electrical conversion, which means the engine is suffering the energy loss (which is insignificant to the engine, and not related to the electrical circuit efficiency). A battery suffers from energy loss during recharge/discharge, so it increases the amount of energy needed to maintain a current and voltage level (the electrical circuit efficiency is decreased). This is compounded by adding more batteries. Batteries have a 2+V lower voltage than an alternator is regulated at. Meaning they are constantly being recharged, energy is constantly being lost. The only time I would add multiple batteries is when someone is competing or listen to music when the car is off. Competition uses very high short duration loads, and listening to music when the car is off requires a lot of stored energy. Most people find simply a H/O alternator is sufficient. [/QUOTE]
