Maybe now would be a perfect time to put in a Optima battery. I heard that even if they crack they don't leak. Might be nice to have that in the trunk.

Optima, roughly $100. Educated guess 57/43 weight bias. Word of advise. Make sure the wire runing off the altanator to the positive post of the battery is at least 10 gaw wire. I had a charging problem with my 85 FW when I did that mod. If you buy the kit from Jegs you should be ok. I built mine from scratch so I had problems. Live and learn I guess.

A search turned up the following:
current model STS: 62/38
DTS: 61/39.
CTS: 52/48
'67 Eldorado: 58/42

I would imagine most FWD Caddy's being at least 60/40.

Hey Shaun,
Good to see you here ;)
The Optima is a great battery for specific applications. Also remember that the Optima can be mounted in any orientation (sideways, on-end, etc.). Also, cable routing is CRITICAL for safety as well as durability.
