Probe 652 car battery

I have bought two probe batteries brand new for two of my cars thinking that i made a good choice as it carried a two year warranty, the biggest mistake as in my opinion it has been nothing but problems even after getting a replacement, i was told that if Im not using the car the battery will die in 3 days so i should disconnect did that, gues what **** battery thenn needed to be charged. Both of the batteries including the brand new replacement has been ****.... Please anyone choosing to buy a brand new battery let this not be even thaught off.
