right behind the left side headlights is a small black box. it has a pos and neg terminals on it[lil black box]. Its basically your in engine connection to the battery, or what you would use to jump it.

i dont know bout you, but my connection is actually just infront of the pass. side, next to the alt. not the left side. and mine is a pos only terminal and the whole pretty much is my neg. im glad they did this kind of set up, looks nicer in the bay

the main reason they put the battery under the back seat is
1. the battery lasts slightly longer because it'* not exposed to the elements The terminals aren't going to corrode and basically weld themselves to the battery.
2. A battery is heavy. Putting the battery in the rear helps somewhat with helping with weight distribution.

Weight distro 100% is the reason. I realise this everytime i'm pulling mine out...

Good idea? Yeah, but i've heard it'* a PITA sometimes. I was thinking of a relocation kit to the rear for mine, but I have a sealed Optima. Don't know if a conventional battery should be in the trunk/pass compartment.

A conventional battery would be fine in the trunk/pass compartment so long as it was vented properly. In the trunk, I don't think that it would be too bad, but it still should be vented. If you have a sealed battery, then you don't have to worry about it out-gassing.

I like it there a dealer tried to press me to buy a SSEi before I was ready so I made a bet-
M- Ok You show me the battery in this car and I'll go get the title to my trade in-
*-ok humm checks under hood, in trunk, under car, in owners book
M- ehh times up It'* under the back seat
him huh, if you knew that why you ask.,
oh I wanted you to look silly.
I hate that dealer I was only there to get a recall work done on my Camaro.

ok, this is driving me crazy. anybody know where i can find pictures of the underseat battery?

Search for TaylorD'* install posts for his system. He dynamatted the seat pans in the back, and should have a pic of it. Or hit his cardomain page.
