Car battery charger?

[ALDJ253]

I am looking for a car battery charger for my current battery. I want to charge it up, and keep it until I can get myself the XS power d5100r for my 2004 acura tsx. I read on xs' website that there are special charging requirements for their batteries. Does anyone have xs power batteries? What charger do you use? I am looking for one around $50 +/- some.

Here are some that I've found:
