What group battery

[MWbirdLOVER70]

Hey guys asking for a friend and for my knowledge. What’s proper group battery for A12 with automatic? Group 24 or 27? My brain says 27

 

[Dave6T4]

Your brain is right!

The A12's were originally 383 Road Runners and Super Bees. The vast majority of these cars left the assembly line with a Group 24 battery with yellow caps. Some of the cars sold to spec for a dealer order may be fitted with a Group 27 with red caps, but that would be an upgrade and shown on the broadcast sheet.

A12 was generally a group 24. Original magazine road test photos back this up.

24 yellow

I learn something new all the time. I thought an A12 would have had a Group 27 like most 440-equipped B-bodies. I never thought about them being 383 cars, originally. Thanks for the info.

I agree and thank you very much

Found my A12's broadcast sheet. It shows a 24. I was surprised too. I'm pretty sure it has a 27 sized battery box, and it's got a 27 in it now. Now I have to go look.......

Another one of those,"Never say Never when it comes to Ma Mopar"
I too have always seen 27's in them.

24 and 27 used the same battery tray.

24 and 27 used the same battery tray.

...and THAT is why you see 27s in em! That and the fact that a 27 is bigger, stronger, and fits.

And C-bodies

This "never say never with mopar" is way overused.

The facts are that the A12 broadcast sheets call out a 24 battery because of the 383 engine. And they are lighter for racing.

Not a mistake or assembly line substitution

I agree as I have been saying it for over 50 years.
Guess I better stop .

The standard battery on an A12 car was the group 24 (59amp, yellow caps) battery. The group 27 could have been ordered as an option. Cold weather climates precipitated the replacement of the group 24 with a group 27 (70amp, red caps). See below.

The A12 option was an upgrade on a standard 383 Super Bee or Roadrunner, hence the oddities on the tag. Many of the details/parts of a 383 car exist on the A12 cars and are not an error but just the way they were built.
