Aux battery tray in a sprinter

Markopolo:

Thanks for the quick response and info. Very helpful. A MBZ converter in the San Fernando Valley (Los Angeles)uses a battery mount from MBZ. Perhaps that will work. I will check with MBZ.

John - those aren't my batteries. Just a photo of what is in a current model Roadtrek. I don't know where the battery tray comes from.

I think Roadtrek is currently using model 8AGC2 6v AGMs made by East Penn. The could have various brand labels.

If they are then the measurements would be approx. 10 1/2"L x 7 1/2"W x 10 1/2"H (each). Looks like they are side-by-side so the pair would be approximately 10 1/2"L x 15"W x 10 1/2"H.

Ideally, all the batteries in a battery bank would be the same type, brand, model, capacity and age. That said I think it would work OK. It's not perfect and you won't find anyone recommending mixing the batteries like that but I've been running a mixed bank for about two years now and all is well. My batteries aren't heavily used though - that might affect them differently.

Other forum members here might let you know about their experiences mixing different batteries in a battery bank.

Markopolo:

We have a 2013 RB 3500 Sprinter converted by Sportsmobile. Our house battery is a 12V AGM 4D 200AH sealed lead-acid battery (measures: L 20.75", W 8.11", H 8.43"). It is located under the van on the driver's side just behind the driver's door. We are looking to add another house battery. If one would fit under the hood and if it is compatible with our existing house battery, we would have the added house battery capacity we are looking for.

I don't know if the two 6 volt AGM house batteries that you have under the hood would be compatible with our 12V 4D AGM battery or not. Do you happen to know the overall measurements of the area occupied by the two batteries and who the manufacturer/supplier of the battery is (our battery was provided by Universal Power Group & Battery Systems)? Your input would be appreciated. Thanks.
John

Thanks, will look into the roadtrex arrangement.

Pete - Roadtrek puts two 6 volt AGM "house" or "coach" batteries under-the-hood on newer MB Spinters. (not chassis batteries)

OIC.I remember now. The newer models than mine ie the dualie models at 22.9 ft have the batteries where you mentioned. Sorry. First thing to go is memory next is--I really don't remember...
I have the big MB German battery for the engine, up front under the hood and it has been trucking along fine since new--ie since 2007!! I use a small solar battery plugged into my 12v and have it sitting on dash.Keeps battery happy.

Ah yes, the memory. Speaking of memory, I can't see how two batteries of any size can fit in the late models of the Mb chassis inthe eng.bay. iff you are moving often, the one battery is adequate. However,if you stay put in fall weather and run the furnace, one must use the generator. I've modified the Benny with resonator and suppertrapp which helps. I'm more concerned with effecting others camping experience. So, my only choice will be AGM batteries under the bed and adding solar panels which are not inexpensive or living with one battery. Really enjoy the Pleasureway and have found the factory support exceptional after my Airtstream experiences. By the way, how we're the steelhead runs this year?
Pete

Didn't catch any steelheads myself but the cohos were big and real scrappers. Campbell River is world renowned for salmon fishing. BTW the RV camping is very good in the area.I like the solar route which I am looking at myself. I use the small ones for trickle charging. cheers

Hi OKPETE. The Pleasure-way Plateau has one battery for the coach located under the rear carpet area on left side under the rear power couch or in one model the rear left side couch. The other battery is the truck battery under the hood. What model is your "2011 Sprinter"? It is true that excessive heat is not good for AGM batteries. I have yet to find a location for a 2nd coach battery, which is what you are talking about. I would like to have one too??

Hello,
All the info I have on the plateaus, indicates that the chassis battery is located under the drivers side floorboard, which is where my chassis battery is located. The location away from engine bay is an indication that MB feels heat is a problem. My coach battery is located on drivers side of engine bay and is a 105 amh german battery. I have a 2012 Pleasureway RB WITH 2011 CHASSIS. Absolutely love this floor plan, because we would leave the couch down anyway. Like being able to swivel both front seats for eating/tv ect. However, would love one more battery. Purchased the tire carrier to remove spare from under bed. Love the space and would rather not have AMG batteries taking up my newly acquired storage space. However, do check your chassis battery location. I've not seen a MB late model that didn't have the chassis battery under the driver side floorboard.
Thanks for your reply and have a good weekend.
Pete
