Considering Optima Battery C70 2000

posted by  someone claiming to be Mark R. on  Mon Mar 3 06:09 CST 2003 [RELATED]

Called Optima:
My C70 Conv. calls for a Type 47 battery w/ 600 CCA (the coupe calls for a Type 48 w/ 420 CCA which is surprising since it's turbo too and based on my chart of BCI group numbers, it doesn't make sense dimension-wise). Optima doesn't produce a Type 47 or Type 48, BUT

I measure my battery (w/o posts) at
10 3/4 Wide by 6 3/4 Deep by 7 1/2 Tall

Their spec on their model 34 INCLUDES POSTS at
10.0" Wide by 6.8" Deep by 7.8" Tall and 800 CCA

Their spec on their model 75/35 INCLUDES POSTS at
9.4" Wide by 6.8" Deep by 7.6" Tall and 720 CCA
(This one has 2 sets of posts - top + side)

Polarity is correct, and the size of the 34 is SO CLOSE!
I don't know how either the 34 or 75/35 would work w/ existing bottom mount.
Also, the 34 has posts slightly in from edge and centered vs. the 75/35 which is out to edge, but also slightly centered so I must check for a different level of play in cable depending which I go with.

Don't know what to do (yet).
