Sorry this answer is late, but if you haven't figured it out already, you can use the H5CKD battery in the Dell Vostro 5502. My Dell Vostro 5502 came with the JK6Y6 battery but did not run that long with it, so I bought a H5CKD battery and installed that instead. You just have one less screw to install it with, but if you install them in the 4 corners it does not move at all.
