They do have different part numbers.

almost sure its different unit, if you check real oem, part number is different, also its more heavier.

most likely its a 800 cells unit SULEV standard for N51, 400-600 for N52.

anyone can confirm, please fill in.

Hmm yes they do. They both say ULEV2 though in the supplement. Isn't the N51 supposed to be SULEV?
