[QUOTE="audioarsonal, post: 4488643, member: 576393"] I know the alt is the main supply once the vehicle is started.However I was speaking from the standpoint that once a second battery is added the first battery isn't required to work as hard when voltage drops to below alt output. As Ignore said it becomes one big battery and doesn't have to dischrage and recharge as much had there only been one battery. [/QUOTE]
