Battery type and location

I have an 07 400SS with Volvo Diesels and 5 batteries. I would like to know what each one does, location and the correct type/model each one should be. I have called Formula and they cannot tell me. They are saying that their drawings do not include where each battery size should go. They can tell me what I need, but not the location. It has been over a day now and nothing. I would like to get the correct sized battery in the correct spot/location. Any help would be greatly appreciated.
 
I have a 40pc, also with five (5) batteries. I'm not sure it's the same but, here goes:

I have four (4) batteries in the engine room - Three (3) are Type 31. They are connected as follows: Two (2) are on the port engine in parallel and they act as the house battery bank, along with starting the port engine. One (1) is connected to the starboard engine and it acts as a starting battery. The fourth battery is a Type 24 and it is connected to the generator as a starting battery.

The fifth battery is a Type 31 located under the forward berth and is used for the bow thruster and/or anchor windlass. In my case, all of the batteries are AGM type. From the factory, they are all flooded lead/acid batteries except for the one under the berth which is an AGM battery. The Type 31's, in the engine room, are marine dual purpose and the Type 24 is a marine starting battery. My main battery charger (80 amp) is a three (3) leg type connected to the port engine room bank, the starboard starting battery and the AGM battery located under the forward berth. The generator starting battery has its own small battery charger mounted on the engine room bulkhead just over the battery.

I believe it is the same for you.
 
Thank you for your response. All of my batteries are in the engine room. One by the generator, one on the outside of the starboard engine and a bank of three in front of the port engine. Formula told me that they do not set this up like this and that one of the batteries should be on the outside of the port engine. I have the electric oil changer pump set as well. I need to know what each of these batteries do and what size/type they should be. I will let you know when and if I find out.
 
After 2 days with Formula, they finally figured out what I need and where the batteries go. Below is what they said I need. The bottom battery is for the starboard side and it starts that engine. The 3 batteries that are the same are located together in a bank in front of the port engine and they start that engine. The last one is the generator battery. All is well in NH.


These are the batteries that were issued to your boat:
(1)Deka 24M-6 (Generator)
(3) Deka Deep Cycle 8T31DT
(1) Deka 1231 MF 1150 CCA
 
One last question before I start installing these new batteries.

The starboard starting single battery is located right next to the generator and it is a standard battery. The port engine has two starting batteries are 650 CCA and are deep cycle. The last one is the generator battery.

The problem with the boat is that the starboard single starting battery has too many things that it is required to run and therefore does not have sufficient power to start the boat due to the load. It starts, but it is under powered.

Here is my question, I know the deep cycle batteries are not designed for starting, but they are doing it on the port engine. Does it makes sense to get a high CCA deep cycle battery for the starboard engine because it runs so many electronics?
 
If you're replacing your batteries, do yourself a favor and get AGM. They last longer, discharge lower without damage and don't require any maintenance. I have a 2006 400SS diesel and replaced my 4 type 31 with Sears branded AGMs two years ago and they run like new. The single battery on the starboard motor works just fine. Look for them to go on sale. I paid $180/ea. Don't get the expensive Lifeline brand. It's not worth it.

I also removed the isolator on the port bank and run all three parallel. I relocated the starboard battery to the starboard side between the holding tank and the macerator. This freed up room next to the generator for a secured storage box and shifted some weight to starboard where it's needed.

Thank you all for your responses. I replaced the 4 batteries myself yesterday. The port side spins very fast, while the starboard side labors. I called the second owner of the boat and he says that the design of the batteries was poor and under powered for the starboard side for the 07's. He recommended to put the batteries is parallel and when i did that, the starboard side spins like there is no tomorrow. It is all good.
 
I realize this is an old thread. But what the heck. Could use some help with understanding the batteries in my boat and purpose. I submitted a new thread for this too.

Gents, can anyone tell me the different batteries and their purpose on my 2007 Formula 400SS with VP diesels and genset? I lost my windlass this weekend due to a dead battery of 2-years old. Not fun cranking 60' of chain and anchor in by hand. Also wondering if I may have a shore power charger issue as I've read about some relay that may go bad and the windlass/bow thruster battery goes dead as a result.

There are 5 batteries total. I have 3 batteries on the port-side, one battery on the starboard-side, and one battery near the middle between the genset and holding tank. Can anyone help me identify them and their purpose? Anyone else have this issue with this battery and/or shore power relay? Lastly, what brand and size batteries did you guys go with?

Thanks for your help.
 
Just to close this out. I replaced the charger relay that is mounted on the port-side just forward the engine in the bilge last fall. I noticed we didn't attach one of the sensing lead wires that manages the charging between the port bank of batteries to the others. After we hooked up the lead wire, the windlass/thruster is now getting charged and is working awesome. Even the starboard engine fires up just like the port engine without running batteries in parallel.
