Charging:

Tip:

Battery should be charged when installed and connected. This is the only means of ensuring charging current is taken into account in capacity calculation of the Battery Energy Manager.

Vehicles up to VIN 4F_5N088139:





- Using the Midtronics Incharge 940 (INC-940) Battery Charging Station, connect the positive cable -1- to the battery positive post.

- Connect the negative cable -3- to the ground (GND) stud of the Battery Energy Manager.

- When requested by the tester, enter DIN value as indicated on battery label.

Vehicles beginning W/VIN 4F_5N088139:

Tip:

Ensure that the charging station cable clamps do not contact each other as the remote positive and negative jumper posts are located close to one another.





- Using the Midtronics Incharge 940 (INC-940) Battery Charging Station, connect the positive and negative cables to corresponding remote jumper posts under the hood.

- For batteries with DIN value 450, enter DIN value 215 into the charger when requested.

- For batteries with DIN value 520, enter DIN value 235 into the charger when requested.

- This value difference is due to the Battery Energy Manager and added resistance in the system between battery and remote jumper posts.
