Side / Top Battery Posts question

Does anybody know if I can use both, side and top battery posts, at the same time?

What I want to achieve is to connect original power cable to one of the posts and use another one for everything else. But somebody told me that these posts (top and side) are not connected and using different circuits ...

Thanks in advance,

PS: if you don't know for sure, please don't post answers

The top and side posts are connected, they come out of the same battery.  (no, there aren't two seperate batteries in the same case).  Yes you can use both attachment points.  I was going to make a smartass comment, but I'll just leave it alone.

There is nothing to be a smartass about - I just needed a simple confirmation. Like I said, I planned to use both posts but some real "smartass" told me that these posts use different circuits which doesn't make sense even from prospective of batteries' manufacturer.

Thanks for your help!

That was "Optima" dealer. And he didn't mean seperate cells - that's for sure.

Anyway ... I'll proceed with my original plans (there is a lot of re-wiring to do).

And again, thanks for your help, guys! 

I agree with you - do your research first and only then ask :)
