has anyone successfully fit an optima battery into an mcs??

the optima battery finder doesn't show applications for either the cooper or
the s.

is the 's' battery a group 42 size?? i thought i saw that somewhere but can't
find it now.

i have great success in my other vehicles w/ the optima.

 

The optima is way too big. I have one.

 

which one do you have?? the optimas come in a couple different flavors
and sizes.

 

my optima yellow top fit...normal size....

 

top or side mounted posts?

were any changes required for the battery mounts to keep it in place??

I have a new 51R, but its too tall... and for sale

I believe a D35 series will just fit (9in tall w/terminals). Footprint isn't a problem. You will have to find an alternative way to mout it though.

I have a D78 - still too tall for my '05.

 

I'll check exactly what mine is later. I didn't have to change anything, just dropped it right in...Fits great.

 

D34/78

 

Maybe something changed then from '02 to '05?

 

I can take some pics or something if its necessary. But dropped in like butter. Used stock battery tie down and everything.

 

FWIW, here's some info I got in the Audio forum: the stock "S" battery is 9x7x7.5.

The Optima battery comes in 2 basic sizes (info from the Optima web site): 9.313x6.813x7.625 and 10x6.875x7.813. CGrant's 34/78 is the latter dimension, according to the Optima web site. I ordered a 75/25 Yellow Top, which has the smaller dimensions listed. I haven't installed it yet, so I can't say categorically it will fit, but I expect it to fit, based on the dimensions.

Hope these numbers are helpful.
