What is the best battery to use for an auxiliary charging system?
I keep getting asked this question all the time, when being asked which is the best battery. I refer to marine or vehicle auxiliary charging batteries or domestic batteries. To say there is a lot of confusing literature about this subject would be the understatement of the year. The information in the literature tends to be correct, but it’s the bits which are not in the literature and the customers’ assumptions that cause the confusion and hence the problems. I will try to answer the question. But in order to save you time, I suggest you adopt the following attitude and make the person trying to sell you these things answer the questions below.
