Does anyone know what model optima batteries will fit the stock battery cables in a 1998 S70 2.3 LPT?

Believe our cars call for a Type 47 battery w/ 600 CCA (or a Type 48 w/ 420 CCA which is surprising since the car's turbo and 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)

Try before you buy. The bottom clamping mechanism is very special and will only work with the right battery. It takes either of 2 lengths. Have a look at the little plastic clip on the tray, toward the center of the car. It rotates off and on and locks the battery in the base.

If you want Plug and Play go with the Interstate MT-47.
Pops right in and uses existing clamp. Die Hard from Sears is also suppose to be good but lately I haven't heard such good things about them- maybe they changed vendors??

Model 34 looks great, but at $200 its pricey.

Ill consider it though when the time comes... 1000 amps!!!

Makes sense to get your alternator cutom wound/rebuilt for 140+ amps as well.
