Note
: Batteries with very low voltage (deep-discharged) cannot be charged using the on-board
socket. They must be separated from the vehicle / on-board network and be charged via the battery
poles using the charging adapter supplied. See comment above with “No battery”.
Note
: Batteries which have been stored for a longer time period with very low voltage are very
difficult to charge or cannot be charged at all or supply full power when fully charged. If a deep-
discharged battery is connected directly to the battery poles, the charger identifies this as deep-
discharged and shows “battery deep-discharged”? / Start charging. Press the “OK” key for at least
one second. The charging process starts and the charging characteristic is carried out.
If error messages are sent, a renewed attempt at charging could lead to the desired results.
Disconnect the device from the mains and restart it. If a renewed attempt does not solve the
problem, the battery must be checked by an authorized BMW Motorrad dealer.
Deep-discharged batteries – „Pause“: If the charger is connected directly to the battery poles via the
charging adapter and this display appears, the battery cannot be charged. Also see the Section
“Problems”. Disconnect the device, if applicable, from the mains and restart it. If a renewed attempt
does not solve the problem, the battery must be checked by an authorized BMW Motorrad dealer.
Problems and elimination of problems
With the BMW charger, you have purchased a product which is reliable and safe-to-operate.
Nevertheless, problems or malfunctions can arise during operation.
Self-test / function check:
If the charger is connected to the mains, the display shows the device identification and goes to the
charging readiness showing on the display: “No battery”. During the start, all 3 LEDs light up for 2
seconds. If the message “No battery” does not show or if the charger displays something else, have it
checked by a BMW Motorrad dealer.
The keys do not react to input:
When operating the device, the keys must be pressed for longer. This mode was deliberately chosen
to avoid pressing the keys through accidental contact.
The device gets hot during operation:
The bottom of the charger warms up noticeably during charging, the heat is given off via the housing.
This is not a defect or malfunction. Observe the safety information on the placement of the device
during charging mode. Do not place on flammable or sensitive surfaces.
