4D and 8D batteries are a size, not a kind. Depending on the manufacturer, they can be found in both 'starting' and 'deep discharge' designs as well as normal 'flooded cell' and AGM construction.

In a deep discharge design, the 4D batteries I have offer about 200 amp-hours capacity. The somewhat wider 8D model offers 240 amp-hours of capacity.

Here is the brochure from the manufacturer of he batteries I have

Dan, 8D batteries are usually used for starting, and I am not sure that they would be a good choice to use as house batteries. They are expensive however, and if you wanted to replace them with alternative starting batts. you may try these. I have a 1981 Eagle Model 10 with a 8V71, that came from the factory with (3) group 31 batts connected in parallel, each with its own cutoff so you can check for a bad batt. When I replaced these a few yrs. ago I bought the ones with the highest amp ratings that I could find. They have lasted a lot longer than the cheap ones that the P.O. used.

Jon, The older coaches used the same batteries for starting and dry camping. That is really not a good idea because then you will be trying to start the coach with low voltage batteries after a night of dry camping and that is bad for the starter. Right now I have two 8D batteries plus a generator battery in my coach. It takes two 8D's because one is not enough CCA to start the 8v92. Each one has 1300 CCA. What I would like to do, but I don't know how to do it, is add two more high amp starting batteries just for starting the engine and separate the 8D's to be used for house batteries. That way the starting batteries should always be at full voltage and the house batteries can be run low and then charged by the engine alternator. I think the six volt batteries were an attempt to get more camping amp hours out of the battery bank but the bigger problem with older coaches is the single battery bank IMO.

There was a thread on here about battery's just about a week ago and I

was wondering why can't you use single 12 volt batterys in our
coaches? Of course they would be the type that hold a charge for
longer durations than a standard 12 volt. I would also install
another set of a batterys for the generator itself. Jon
