Review snippets: The media could not be loaded. I installed the NOCO GENIUS2D on my RAV4 after relocating my AGM Yellowtop battery to the rear. It bolted on easily using low-profile M8x1.25 10mm flat head screws, and while I haven’t permanently mounted / Smaller than I expected but much easier to install because of its size. The mounting strap has two holes to install the plastic snap-on back to the metal of the vehicle inside the engine compartment using two self-tapping screws (provided).
