[Gasoline Fumes]

I thought I should update this thread. I've had a Schumacher SC3 charger for a while now. Works fine for charging a pair of deep-cycle batteries in parallel. While that's probably a lot more battery than it's designed for, it barely gets warm, even in a closed hot car. The built-in fan cycles on and off to keep it cool. It was a Walmart impulse purchase, but I'm totally happy with it. Lightweight and fully automatic. Lives in the car.
