6-volt battery question

[53saratoga]

Hi, I have a optima 6-volt battery that is suppose to power my 331 hemi engine. I just started it for the first time with the 6-volt and it started up but in the process of starting, it sounded like it didn't have enough power to get it going. Is that normal for a 6-volt battery because with a 12 volt battery the engine jumped to life right away. But that could be because the 12 volt is bigger to. But is that normal for a 6-volt battery to do that.

Check all your connections, and be sure that you have the proper gauge battery cables. A six volt system requires 0 gauge cables.

It's your cables. If they're not 0 guage or

00 your voltage is not getting to the starter.

(Kind of like trying to get a 5/8 stream of

water out of a 3/8 hose.) 12 volt cables on a

6 volt car are usually the problem.

If you have the right cables they clean them.

WOW you guys are amazing I would have replaced the whole system to a 12 volt if I couldn't of figured it out. I'm glad I asked first It was a 6 gauge wire so 0 gauge is really thick then. That gauge wire makes that much of a difference?

[Steve Braverman]

It's Ohm's Law. Since you have half the voltage, you need twice the amperage.

That's true
