[QUOTE="loopkiller, post: 5846510, member: 601690"] You have to be very careful with gel batteries. They are very fragile when compared to other battery technologies. And to be absolutely clear here, Optima is an AGM battery, not gel. Now to answer your question directly, yes adding additional batteries is an additional load for your alt. Is it a small addition or a large addition is the real question that you should ask. Two Optima batteries would have a relatively small ESR compared to a single flooded battery. So in that sense, the two AGMs would present a smaller load. But, if you drained both of the Optima batteries with the key off, then started the car, they would for sure draw much more than your single flooded battery. So in this case, yes they would be a much larger load. Sometimes questions are not as simple as you would like them to be. It is not a black/white question. It depends on many other factors.
