KnuKonceptz has redefined Ultimate to bring an even more versatile battery terminal to market. The Ultimate Battery Terminal UBT-20 offers symmetrical application of our popular Top Post and Vertical Top Post adapters. Installers can now easily manipulate any factory battery application with screw ports on both left and right side of the terminal. Attaching the Ultimate Battery Terminal to a recessed battery post is no longer a challenge thanks to our new patent pending clamp screw design. The clamping mechanism can be accessed from the front or rear face of the UBT-20. Installers simply need to arrange the interchangeable brass dowels within the UBT-20 according to application. The UBT-20 also holds a variety of cable sizes by set screws and the two ring terminal ports. Each UBT-20 accepts one each 1/0 and 4 gauge wire. These two set screws are accessible from the bottom of the terminal, even after the insulated color coded cover is in place. The ring terminal ports can hold any gauge cable via the 8mm stud or attach one of our Top Post adapters for easy OEM integration. Like all automotive battery terminals, the UBT-20 is made to SAE specifications, which means that the positive and negative terminals are machined to different diameters. This is a reverse polarity safety feature so that installers cannot tighten a negative terminal onto a positive battery post and cause serious damage to vehicle electronics.
