KnuKonceptz studied countless terminals options while developing the Ultimate Battery Terminal. Our top priority was a bulletproof battery post clamping system that would never fail. Using cross dowels that can be replaced on the fly created just that. Solid brass pins are inserted through the bottom of the UBT-840, should the installer cross thread or over tighten, these pins are easily removed and the terminal safely restored to functional in seconds.
In addition to a never failing clamping system, the UBT-840 allows for instant OEM integration via the optional Top Post Adapters (sold separately) offered in both vertical and horizontal orientations. Installed in seconds, this adapter allows installers to use the vehicles OEM battery cable, which is great news for car enthusiasts who lease their vehicles. ALWAYS check the installation area for clearance when modifying the height and width of the battery connection!
The UBT-840 also holds a variety of cable sizes by set screws and the optional ring terminal port. Access to the three set screws is from the bottom of the terminal. Each UBT-840 accepts one each 1/0, 4 gauge and 8 gauge wire. These screws are accessible even after the insulated color coded cover is in place.
Like all automotive battery terminals, the UBT-840 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 damaged to vehicle electronics.

Q: How is wire secured to this battery terminal?
A: Unscrew the allen screw from the bottom of the battery terminal; strip the jacket off of the cable; insert the bare wire into the battery terminal; tighten the set screw into the terminal, compressing the bare strands of the cable. If using the insulated color coded cover, you will need to thread the cables through the cover’s rear opening. This hood protects the exposed area of the cable at the connection point.
Q: Is there a difference between the Positive and Negative top post terminals?
A: Yes, the Negative top post terminal’s opening is smaller in diameter so that it can not be mounted on the positive battery post and cause a reverse in polarity within the vehicle..
Q: How can I connect 2 Gauge wire with these terminals?
A: The 0 Gauge port or ring terminal port can be used with a 2 gauge cable as well
Q: Can I purchase additional cross dowels for this model?
A: Yes, additional cross dowels are available for purchase. They are £0.99 each
