  • Don’t touch any wrenches between the battery terminal and any other part of your vehicle.
  • Discard the old battery according to local laws.
  • Read your owner’s manual to determine if there is a reset procedure for your vehicle, expecially if it has a Battery Monitoring System (BMS). Follow the procedure to avoid problems.
