Hello All, I recently purchased a 35 foot chirs craft. The boat currently has two 4D battery's. Both battery's are just over a year old. The boats Battery charger is not functioning and after inspection does not appear is it will ever function, which means I need to purchase a new battery charger. My question is are the 4D battery's the correct battery for my application? I am installing a few TV's as well as a surround sound system LED surround lighting. I also plan on eventually installing a HVAC setup of some sort on the boat. Should I stick with the battery's I have or switch to something else. Also I noticed that most chargers that work on 4D and 8D do not work on anything else and vise versa.
