anyone use 2 8 vlt. batts.?if so what brand and hows it workin out.

I haven't seen or heard of a eight volt car battery in years I use to use them in the early 6 volt V8 cars like the pre 1953 Olsmobiles, Cadlilacs and so on, any 6 volt hard starting V8 was a potential benifactor of the extra two volts

I had a cutomer use 2 Golf Cart 8v batteries in his car....worked great he wanted them for extra ballast.

We run 8 volts in series in our mud truck with no charging system, they are working good, I got them thru Interstate but dont know what brand , they hold a higher voltage a lot longer than 2 12s in parallel and are good ballast

the deka dealer here has 8v batts but didnt seem to think they would work in a race car with no charging system do to a weak reserve,they are 650 cca each.i just got spoiled with my 16 turbo starts but right noww cant see spendin 600 bucks for 2,mabey ill try just runnin one for now.

Two 8 volt golf cart batteries would for sure give you some run time for your accessories. But your looking at 140ish lbs?

EDIT, 64lbs a piece from Interstate.

We have used 2-8volt batteries in series for over 10 years in our SS cars, they are light (about 70 lbs for the pair vs 84 for a pair of Turbostarts), cheap (about $120 for the pair), change them out after about 5 years, readily available at auto parts stores and like places.I don't remember the CCA's right now, something around 650-700 each, they are considered a commercial series battery and are generally designed for lots of charge/discharge cycles.
