Just a quick question, I'm looking at house batteries and I don't know what a 6D battery is?
Is it an 8D in 6 volts , or is 6D just another group size.
Thanks
Pat
Group size between 4D and 8D.

Thank you! Great battery reference chart.
4D and 8D are both 12 volts. I have never heard of 6D. The 4 and the 8 is a size reference. In all my years working with heavy equipment 8D is the most common.
Used in many newer coaches as house batteries.

Bet that is a typo. Suspect 8D's.

But, has anyone seen a 6D installed in a motorhome by any RV manufacturer???
Learn something every day.
The 6D 6v 120ah battery is commonly used in India in railway cars for lighting and air conditioning.
The 6D 12V appears to be between the 4D and 8D in size. See battery group size chart below.
If you saw it in reference to a US made RV, probably should be a 8D or 4D, which are both 12V.
I've sold high end Newmar King Aire RVs, Country Coach, Monaco, some on Pevost Chassis, and have never seen a 6D battery that I know of. I've seen many other group sizes, never a 6D. My guess, maybe a typo, could have been 6 (the number of) 8Ds.
I have seen 6V batteries connected in combination of parallel and series to yield 12V from 6V batteries, but never any called 6D. And yes the recent King Aires have 16 6V batteries. In fact all their recent diesels use 6V batteries.

Lot of typos then, OP has a 07. MOT ad for an 08 and a 2011

With all electric coaches, 2 or 3 8D's is marginal. They might use six 6D's because they cannot fit in six 8D's
And yes have seen either 4D's or 6D's in a King Aire at MOT last year.
I stand corrected. This is from the Newmar owners manual. All their diesels use 6V.
"The House Battery Bank is necessary to operate everything a customer may require in order to live in the unit. These batteries can be either 6 Volt deep cycle (all diesel coaches) or 12 Volt deep cycle, depending on the model and brand of the coach".

Think we need to hear from pibutler again and see why he is looking for 6D batteries.
Believe newer King Aire's use sixteen 6 volt batteries, probably easier to change out than six 8D's :D :D

Hi,
Thanks for the great feedback, there's a 2013 40' Nimbus at MOH that shows it has 4 6D Batteries. The chart jcus posted does show 6D Batteries. I was just curious if that was correct, but the chart does show 12 volt 6D.

(4) BCI Group 6D batteries are a little skinnier and a little taller than a what may be more common 8D, but either way you will have quite a few amp-hours to draw upon. What with that electric cook top and all.
The only downside I see is if those really are BCI 6D battery cases, you won't be able to slide in a set of BCI 8D batteries.
Does your Seagrave have a big pump in front with an air dome?
Good picture of the battery bay. But 8D's, 6D's, and 4D's are so close in size, You would probably have to actually see a label, or measure battery to be sure.
4D batteries are quite a bit narrower than 8D batteries, 31/2 inches narrower and 6D batteries I don't know anything about them.
BCI Group Size lists the widths as 8 3/4, 10, and 11 1/8 inches wide. The heights are 9 7/8, 10 1.4, 9 78 inches tall. And they're all 20 3/4 inches long.
Thanks for all the great feedback.
"Does your Seagrave have a big pump in front with an air dome?" No pump up front but it does have a large mechanical siren. Seagraves are the best made fire engines.
Congratulations on your Seagrave but the piston pump models seem alive when working, as does the original Curved Dash Oldsmobile at idle, rocking gently upon its springs.
When do you pick up, your new to you, 2017 IH45, now that it has already the taken initial depreciation hit and has enough miles on it to be sorted out?
Just talked to Aubrey Lee at MOT. Aubrey used to be the electrical guru at FOT. He told me Foretravel has never used 6D's in its coaches. Generally 8D's or 4D's only. Must be a new guy making the ads.
