trunk mounted battery, 78 spider...

I've seen two different ways the bracket is put on...I assumed the hold down bracket goes straight across the middle of the battery like every other car.

but I come across these two photos showing the angle iron cross piece along the top edge of the battery. Not sure about the geometry but it looks like the battery could lift during a left turn. Or is this correct because part of the battery tray on that side is unsupported?

I am about due for a battery nd I'm gonna go with a lithium iron. A fraction of the weight and size... will probably mount it in the tool kit area..

Go to antigravitybatteries.com. they have many car batteries to choose from. They ain't cheap.... I have had one in my dual sport for almost 7 years. No problems, is mounted upside down, weighs barely over a pound and 2"x 3"....

I run a "battery tender" brand lithium battery in mine. It's intended for motorcycles, but starts the Alfa fine as long as it isn't below freezing. The size and weight difference is quite dramatic. Plus, you can mount it in any orientation. If you go lithium, I'd recommend one that has protection against deep discharge. I once killed one by forgetting to put it on the battery tender for a month while there was a small parasitic drain.

figured out why the PO put a 24F battery in...the correct size 24 is $30 more...same exact battery, just posts are reversed. So why does it cost $30 more???

Maybe there is another battery group option that is not a premium for a reversed post? I've seen a post about Group 34 for the newer Spiders...

The cost has to do with the market place. There probably is a smaller market for the "F" version. So they have to reset the line up to make "F" batteries then back again for the other version. They probably don't have a permanent line for this version. Numbers control everything in manufacturing world.

that's my theory too..."economies of scale" is why a Ford and Ferrari cost pretty much the exact same investment to produce...but that cost is spread over fewer units, boosting the unit cost of the Ferrari.

But in this case...the Group 24F is way more common is seems...

I wouldn't ay Ferrari cost the "exact" same to produce. It really does cost more to make things like a carbon fibre chassis (specialized equipment and slower production time) and v12 engines (many additional parts to manufacture). But economies of scale do partially explain why Chevy can make a c8 Corvette for $59k when no other manufacturer has made a mid-engined car with a v8 for less than $100k (inflation adjusted, of course).

well I didn't mean a ford escort...but all cars, regardless of sales price, are closer in production and material cost than you think....upfront design and facility costs are pretty close as well...it's a matter of how many units you can divide those fixed costs amongst...kinda like how walmart can under cut almost any other retailer.
