Kirkland battery's are junk, the po put one in my Camry and it leaked acid all over the place. I would buy either an Interstate or an OE. The Mercedes battery's are nice, their made in Spain and seem to be sealed well.

Btw if you are going to store the car for a few months you should take the battery out and keep it in a place that will not get below freezing. Also throw a charger on it once and awhile.
