3 batts on H31
I have a three-battery system. Two house and one starting. I have a two bank charger that I use to top off the batteries before and after sailing, but I don't leave it on while I'm away from the boat during the week. I don't have a refrigerator and have found this system to handle the water pump and lights with no problem. I recently purchased a new starting battery. I read about them in the various catalogs, but ended-up with one from Wal-Mart. It will be interesting to see how long it lasts, but the price was right. I can buy 3-4 of them for the cost of something fancy, like an Optima.
