How to Use NOCO Genius G4

To safely and adequately charge a battery, you should follow the following steps:

  • Ensure the battery clamps are correctly connected and the AC power plug is connected to an outlet.
  • Turn on the charger by pressing the power button labeled ON.

  • Proceed by pressing the MODE button. From the options presented, select the mode that best suits the needs of your battery. This will initiate the charging process.
