|
 Note
| The battery temperature must be at least 10 °C (50 °F). |
| – |
Turn off the ignition and all electrical consumers. |

Clamp the red charging clamp “+” to the positive battery
terminal. |
Note
| In the case of vehicles with a start/stop function and an

start/stop system will malfunction if it is connected to the
negative terminal on the battery. |
| – |
Connect the black charging clamp “-” to the negative battery
terminal. |
| The battery charger recognizes the nominal voltage of the
connected battery (6 V, 12 V or 24 V) and begins the charging
process automatically. |

sustain charging after approximately 1-7 hours. To achieve a
100% charge status, the battery should remain connected to the
charger for that long. |
