How much do the optima vents stick up out of the battery? In the pic on page one it looks light there might be enough plastic to possibly clamp a piece of hose..perhaps a piece of large vaccum hose onto the vents and then run it down to tap into the stock vent hose somehow.

I'm wondering what type of plastic the top of the Optima is made from.

Knowing that, a proper adhesive may be chosen to adhere elbow fittings to it.

I'm going to try and see if I can get the 880 CCA battery instead for some more power. (Riviera vent tubes will be required however.)
The Interstate was an 880 battery, and had a price of like $140. The other two I found were 770.
Do you remember what group # those batteries were? (79 or 100)

No I don't remember. I remember one had an MTR-79 part number, but I don't recall which one.

As far as the vents go, I would have to measure when I get home, but I would say the plastic part sticks up at least a quarter inch. I don't know if it matters, but you can see from the picture posted on the first page that the plastic doesn't go all the way around though. It has like five sections to it cut out on the sides. So my assumption is that when the valve opens, the grey part pops up allowing the gas to leak out the sides.
