Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
I called Optima directly and they recommended the Yellow instead of the Red battery because I have some stereo amps.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I am the lucky recipient of a certificate good for the Optima battery of my choice (has to be used in the next 5 months). I don't "need" a new battery, but I have certainly heard good things about them and they appear to weigh less than traditional ones. There seem to be several options (red top, yellow top, different sizes, etc.). Other than making sure that it physically fits into the space, any guidance on which one to choose?

POST 2Original post

I was thinking about doing this soon. I called Optima directly and they recommended the Yellow instead of the Red battery because I have some stereo amps.

POST 3Original post

I installed a Red Top 75/35 in my 996 race car last spring. It saved about 20 lbs and worked great. The different colored tops identify batteries for different purposes. You will want a red top but probably a different model than I went for. I think 34 or 34/78 are better suited for daily drivers. To install it you will either need to purchase an adapter kit that allows you to use the OEM mounting hardware or do something custom. You also may need to extend your cables. I didn't need to but apparently others have. Go to www.optimabatteries.com for more info.

POST 4Original post

Go the the battry selector and choose your vehicle. In my case, there are no available batteries for any automobile. Must be a glitch in their website. FWIW, my 996 from July 1998 still has the original batteries, 26K miles, with the trickle charger. Very well worth the investment.

POST 5Original post

i installed a red top in my C4 with little problem. Didn't even need to purchase new wires or anything. Works great. Bob

POST 6Original post

There is a thread on it here with most of the details and minor changes that need to be made.

POST 7 / ORIGINAL POSTEROriginal post

Wow, I expected information, but this is superb, even by Rennlist/Renntech standards. Thanks everybody!
