6 Pound Battery
Has anyone tried this http://www.voltphreaks.com/home.html -- 12V battery (VPHR18) that weighs 6 lbs. For the price, $675, on a per pound basis, better weight savings for a Porsche than many other things.

"Tony from Voltphreaks here. Minor correction, the Optima group 34 has 7 times the Ah rating, which means how much ENERGY it carries. Power though, the Optima has 3 times the POWER rating. Energy is how long it can run the stereo with the car off for, power is how much instantaneous amps it can provide.
Yes that's the disadvantage, low Ah ratings compared to heavier batteries. But about the stereo, it only affects listening time when your engine is off. When your engine is on, the alternator is what's supplying the energy. As for an aftermarket amplifier, any of the Voltphreaks batteries would work, they are VERY powerful, and 300 amps is a LOT, it's equal to 3600 watts of amplifiers! Our smallest model (VPHR7) would work, but you wouldn't be listening for very long, due to the low Ah rating.
Anyways just wanted to comment that these batteries can handle any stereo just fine as long as listening with the engine off isn't a priority. And the Red Tops you mentioned are great batteries!

Not to hijack this thread, but as a general question...has anyone used anthing by Odyssey smaller than the 680? That's roughly 15lbs and they make some as small as 12 lbs, but that's a motorcycle app, so don't know if it'd turn the car over...The battery at Voltphreaks is certainly incredible as is the price...being light ain't cheap!....of course Linton is in a whole different league...surprised he doesn't have two pea size dilithium crystals for a power source as that would compliment his 964 F1 he's building....
Be interesting to know what the smallest battery for the best price is...

I seem to remember reading that cabrios were fitted with bigger batteries than coupes, as their electric roof mechanism needs lots of juice. If true, then optimum battery will also depend on car type.

Some of these batteries need special harnesses for fitting.
Will the voltphreaks fit right in, and will there be any practical downside for a street car?
Isn't the porsche OEM battery lightweight?

"will there be any practical downside for a street car?"
Yes lots of downsides , not many upsides .
The AH rating is small , any battery drain is going to kill the ability to start the motor .
Leaving the radio on is going to kill the ability to start the motor .
Leaving the lights on ...
If you have a little problem starting the motor , the battery is going to be flat quick .
"Isn't the porsche OEM battery lightweight?"
The standard lead acid battery isn't "lightweight?"
Using a tiny battery like this on the street would be like using a 1 gallon fuel tank .
Yeah its lightweight , but its not real practical .

Bob's GS is a cabrio but has many different configurations and has a Manual top (bob correct me if i am wrong here it's been a while since we spoke about the top). It also has a Hard top that can be used (with sunroof).
A Battery should be usuable on the street in normal situations to be considered. This looks like it could work actually. something to test for a month or so (both with trickle charging and w/o)
I have used the 680 before onthe street with no issues - the car was driven daily as well.
"Isn't the porsche OEM battery lightweight" - No, there was a lightweigh battery used for the RS and the Cup USA cars - but it only weighed apx 5lbs less (lead acid) it is advaiable over the counter from porsche if you want to go that route.

Contacted the voltphreaks guys via email and they told me the 4.5 battery would work fine to crank and run my 993TT powered 964. So guessing the 6 lb would be equally as good.
I don't even have a radio so no need to worry about that. Just wondering if I can leave the car locked and not have the little blinking lights on the top of the door lock stems drain the battery....Good thing I've got AAA

I can't think of any good reason to stick such a lightweight battery into a street car. Way to many downsides for an insignificant upside. Yes, it makes a difference as you struggle to get that 2300 lb car down to 2200 lbs, but for a car that weights 3200 lbs? Get real, a difference of 20 lbs in a car that weighs 3200 lbs is about 0.6%. It's not going to matter.

I'm not convinced this is ever going to be a "street car" in the usual meaning of the words.
"Ultimate lightweight 964 showcase for advanced technology", maybe. In that context, a 6 pound battery seems just the ticket, if it has the required capability to start the car...which it sounds as if it has. Doesn't sound as if anybody else has tried it, though.
