[RallySnake]

I went through that decision about 6 months ago. After a little research, I bought a Bosch Platinum Series battery. I got the small one with only 450 cranking amps. It's about half the weight of the type 34 Optima red top. It's much smaller too with the plates arranged flat instead of spiraled. In California we don't have to worry about cold weather starting problems. In a colder climate, I would have bought a bigger one.

It has been working great in spite of the 4 HID rally lights and all the rally computers in the car. I keep the battery tender on it when it's not on the road except when I am out of town. We ran a rally to Las Vegas last September and it sat outside the hotel with the 2-way alarm system running all night. Started fine.
