What is a good all around battery charger to have with you at the track?

I have this.
It works great and actually recovered a set of golf cart batteries so it's paid for itself already.

12V? What do you want to use it for? I have a very basic Sears on wheels which was made by Scumacher for my 12v battery. I have an alt. so I hook it up when I cool the car so it's not drawing the battery down while cooling. I could use a small carry around just as well for what I use it for. Just easier on wheels and it has followed the car nicely to the staging lanes.

Nice!

I like a well-trained battery charger
