Battery (MXC/EXC)

The battery is located under the seat and is maintenance-free.
It is not necessary to check the electrolyte level or to refill water. Simply keep
the battery poles clean and slightly grease them with an acid-free grease if
necessary.
Removing the battery:
First disconnect the negative and then the positive pole of the battery.
Remove the filter box cover and unhitch both rubber bands [1].
Remove battery.Install the battery with the terminals facing the front (see illus-
tration), connecting the negative terminal post to the battery last.
– IF ELECTROLYTE (SULPHURIC ACID) LEAKS FROM THE BATTERY, PROCEED WITH
GREAT CARE. THE ELECTROLYTE CAN CAUSE SEVERE BURNS.
– IN THE CASE OF SKIN CONTACT RINSE THOROUGHLY WITH WATER.
– IN THE CASE OF CONTACT WITH THE EYES, THOROUGHLY RINSE EYES WITH
WATER FOR AT LEAST 15 MINUTES. IMMEDIATELY CONSULT A DOCTOR.
– THE BATTERY IS A CLOSED MODEL BUT CAN NEVERTHELESS EMIT EXPLO-
SIVE GASES. AVOID SPARKS AND OPEN FIRE NEAR THE BATTERY.
– DEFECTIVE BATTERIES MUST BE STORED OUT OF THE REACH OF CHILDREN.
ENSURE PROPER DISPOSAL OF DISCARDED BATTERIES.
– TO AVOID DAMAGE, DO NOT REMOVE THE LOCKING BAR [2] !
– NEVER DISCONNECT THE BATTERY WHILE THE ENGINE IS RUNNING. THIS
WILL DESTROY THE RECTIFIER-REGULATOR.
– THE BATTERY MUST BE INSTALLED WITH THE TERMINALS FACING THE FRONT
(AS SHOWN IN THE ILLUSTRATION), OTHERWISE ELECTROLYTE CAN ESCAPE.
BATTERY STORAGE:
When preparing the motorcycle for a longer period of standstill, remove the
battery and recharge it. Storage temperature: 0 - 35°C (30 - 95°F). Do not
expose to direct sunlight.

Charging the battery

Remove the battery and check the charging level. Use a voltmeter to
measure the voltage between the battery poles (off-load voltage).
Accurate results can only be obtained if the battery has neither been charged
nor discharged during a period of 30 minutes preceding the measuring.

If the battery is empty, it can be recharged for a maximum period of
10 hours at 0.4 A and a maximum of 14.4 V.
– TO AVOID DAMAGE, DO NOT REMOVE THE LOCKING BAR.
– ALWAYS CONNECT THE BATTERY TO THE CHARGING UNIT BEFORE TURNING
THE CHARGING UNIT ON.
– WHEN RECHARGING THE BATTERY IN CLOSED ROOMS THERE IS SUFFICIENT
VENTILATION. EXPLOSIVE GASES ARE RELEASED DURING THE BATTERY
CHARGING PROCESS.
– CHARGING TIME AND CHARGING VOLTAGE SHOULD NOT EXCEED THE STATED
VALUES. OTHERWISE ELECTROLYTE WILL BE RELEASED THROUGH THE SAFETY
VALVES.
– AVOID QUICK CHARGING IF POSSIBLE.
