Welcome to Sunline Owners Club! Congrats to you on your "new" Sunline.
The battery, if you are buying a new one, look for one that is called "Deep Cycle". There are 3 basic types in the lead acid world of batteries.
Starter Battery: This is the one in your auto. Lots of quick power.
Marine/Deep cycle: This is a hybrid between a starter battery and a true deep cycle battery. It can be used on a TT and often times is. This type was geared for boating that sort of did both worlds, started the boat motor and had long drain cycles.
Deep Cycle: This is the better one if you can find them for a TT. You are not starting an engine with it and you are able to do constant discharges and not hurt the battery as long as you do not over drain it. They are made for deep discharges or long periods of use and not hurt them. Starter batteries are made for high power short uses.
As Clueless Camper stated Wal-Mart sells them and the last I knew Johnson Controls made them for Wal-Mart. There are 3 types at Wal-Mart
Group 24 Deep Cycle. This is the standard size battery that would come on a new Sunline even. If you are not doing a lot of boondocking then this battery size will do you well.
Group 27 Deep Cycle. This has more capacity then the Group 24. It has more amp hours of power reserve. It is also a larger case size and most times will not drop into the battery tray on the front of the camper. Not a big deal but you may/most likely will have to make a conversion systm to hold the larger battery.
Group 29 Deep Cycle. This one is even bigger then the Group 27. Again more reserve amps to go longer or be able to use more power and it has a larger case then the Grp 27
I my self have 2 group 27's batteries because we do go camping without electricity often and one of them is a Wal-Mart battery. I did have to make special mount for the TT tongue and needed new battery boxes.
After learning more... if your really serious about camping off the grid, then going to multiple 6 volt batteries offers more power.
So this all comes back to what are your camper needs? We used the standard Group 24 battery system with no issues at all for several years but we also have shore power at the campsites and could plug in. Unless you are wanting to get into boondocking the grp 24 will serve all your needs.
Hope this helps
