Description

This 36 volt 12 Ah battery pack is a set of three Universal Power Group UB12120 AGM batteries. It is the most common battery type in electric scooters, including most generic brands and the 36 volt Razor MX500 and MX650 dirt bikes.

Choose the batteries alone or with a universal harness. The harness has butt-end splice connectors so it can be spliced in or modified to fit; it is not plug and play, and some modification will be needed. With the No Harness option you reuse your existing wires by soldering or with tab (spade) connectors. Most recreational scooter wiring is soldered to the terminals, so reusing it can be difficult or impossible.

The batteries are sealed, non-spillable and maintenance-free, with low self-discharge, good deep discharge recovery, and a flexible design for multiple installation positions. The pack has a 1-year full replacement warranty. For about 25% more run time in the same size, see the 15 Ah 36 volt UB12150 AGM battery pack.

The UB12120 replaces any standard 36 volt 12 Ah battery pack, including these battery models:

  • D12S (AJC Battery)
  • BP12-12/EP12-12 (BB Battery)
  • EXP12120/BLMFM12.12 (ExpertPower)
  • NP12-12T (EnerSys Genesis)
  • ML12-12 (Mighty Max)
  • ES12-12 (MK Battery)
  • PK12120 (Power King)
  • PS-12120 (Power-Sonic)
  • GB12120 (PowerStar)
  • SG12120T2 (Sigma Power Systems)
  • SP12-12 (SigmasTek)
  • TR12-12 (Tempest)

Great deal and shipment was fast. The wire harness was not the right one for my x treme x 360 scooter but I made it work. Thank you.
