Real Fiero Tech

I've been looking at putting my Fiero on a bit of a diet. I found these Carbon Fiber Batteries by Braille:

Do you think this will have enough power for a regular summer/fair weather car?

I figure this would be an easy 30lb savings with little work.

looks good, but pricey. How much does a stock battery weigh?

Anywhere between 30-50lbs I think. Alot is dependant on the brand and type.

I damn near got a hernia lifting my Orbital battery into the car. Those are effin heavy.

What is special about these batteries besides the carbon fiber box?

I fail to see how a CF battery would save you decent weight - like 90+% of the mass of a LA battery is in the heavy lead plates and electrolyte inside. It looks like most of the weight savings is in its diminutive size.

You could probably use a Honda battery, as they're pretty little, and it started up my 383 once in a pinch?

This is an interesting read on these "specialty" type batteries.

I run the Odyssey 680 as seen further down the page. It doesn't have a ton of reserve but works well with regular driving. I do keep a battery maintainer on the car during the week when I'm not driving it. Weight savings on that battery are fairly substantial.

Deja vu. I think somebody else posted this link before.

First, comparing a plastic battery to a carbon fiber battery is a non-issue. They weigh the same. The real weight is in those damn lead plates that fill them up.

Second, that's a $240 motorcycle battery with a carbon fiber cover. Skip the middle man and buy a $30 motorcycle battery and get the same performance and life out of it. A motorcycle battery will start a car just fine. Probably not a high compresson 454 but doubt anyone here has to worry about that. You will get less lifetime out of them. They've got 1/3 the electrolyte, 1/3 the battery plates and 1/3 the weight. They've also probably got 1/3 the life in a car application. Figure on replacing it every year or so.

Just don't leave anything on when the engine's not running....

Thanks for the replies guys. I think I'll end up going with one of those odyssey 680's. I like the price of that one alot better.
