I can relate to those who say "I would never install 8Ds again" but they do lend themselves to certain requirements which other types cannot fulfil. For instance on our boat there six 8D AGMs, racked two high, and a 4D in a low locker on the port side. Access is from the side of the companionway which is inboard of the locker. This location keeps them out of the engineroom and their weight offsets that of the pony engine on the starboard side. The batteries are simply slid into place with no top access needed. That space configuration could not be utilized by batteries which need servicing (water or terminals), and/or have terminals at each end. Heavy? Sure, but that's what hired help is for. Besides, at my age I need all the exercise I can get! Regards, John "Seahorse" **************Start the year off right.
