NOTE:
- For the vehicle equipped with a battery sensor, be careful not to damage the battery sensor when the battery is replaced or recharged.
  1. When replacing the battery, it should be same one (type, capacity and brand) that is originally installed on your vehicle. If a battery of a different type is replaced, the battery sensor may recognize the battery to be abnormal.
  2. When installing the ground cable on the negative post of battery, tighten the clamp with specified torque. An excessive tightening torque can damage the PCB internal circuit and the battery terminal.
  3. When recharging the battery, ground the negative terminal of the booster battery to the vehicle body.
