Hi,
I have a 993 C2 'narrow body'.
I just changed my 6 yr. old "Diehard" (that DID 'die') to an Optima RED TOP Type 35. It was $110. It's also a SEALED battery so no more 'vent tube' shenanigans.

g_murray - did the optima type 35 need spacers/brackets or anything to fit and hold tight? i have a c4s, given you highlighted you had a narrow body, does that mean it takes a different battery than wide body? (i would guess not, i would think front trunk is the same)

Hi,
I did NOT need any 'extra brackets' to install, though, in the box that it came in, there was an additional "plastic piece" that could be used to 'raise' it off its base ...if need be.
The 'new' optima redtop just slid into the same space (as the old diehard) and I just secured it down with the existing 'semi-circular'-shaped w. single bolt bracket thingy.
You should have no problems.
Just make sure that you get the battery with the +ve terminal that will face AWAY from the car body and is oriented towards the nose of the car, and, obviously with "big nipple" posts rather than ones that screw in.
BTW, just for grins, since I had the old battery out and that whole 'battery area' completely exposed - I took the opportunity to wash/flush the whole area down with a solution of baking soda and warm water. I must admit there was no signs of corrosion or acid damage ...but I figured "whilst I'm in there".
If you DO this - just remeber to DRY and SOAK UP all traces of baking soda otherwise, over time, it will dry to a 'white dust' and sometimes even turns brown like it has been 'carmelized'.

I just installed an Interstate 91 (on my invoice it shows as an MTP-91), which went in easy. Just make sure they give you the vent kit.
But 993's take a "Group 48" battery.

If you use a convential battery use one of these:

I have them in all my cars and they work really well...just don't get them wet or like any water absorbing material you'll get rust. No affiliation etc.

Just came back from Costco where a lot of fellow RL'rs have purchased Optima batteries and the + - were on the wrong ends.

I just put an Optima 34R in mine. The R is for reverse terminals and gets the + to the front center of the car. I still had to straighten the curve in the + cable terminal clamp. The bottom hold down went on just like a conventional battery. Ken

, if I recall correctly. The 34(R) is the one to get, but I couldn't find one locally.

I just bought a Yellow Top Optima D35. Perfect fit. Better choice for me as my car is not driven daily.

From my experience the gel batteries, at least the red tops, lose their charge quicker than a regular battery. In addition I've had two go bad on me within a year of buying them. My Interstate batteries last 6+ years and work just fine without any damage provided you keep the vent properly hooked up and use a battery mat. I'm not at all convinced the gel batteries are worth it.
