16.6 Charging the 12-V battery (SUPER DUKE R)
Warning
Risk of injury Battery acid and battery gases cause serious chemical burns.
– Keep 12 V batteries out of the reach of children.
– Wear suitable protective clothing and safety glasses.
– Avoid contact with battery acid and battery gases.
– Keep sparks or open flames away from the 12 V battery.
– Only charge 12 V batteries in well-ventilated rooms.
– Rinse the affected area immediately with plenty of water in the event of contact with the skin.
– Rinse eyes with water for at least 15 minutes and consult a doctor immediately if battery acid and
battery gases get into the eyes.
Note
Environmental hazard 12 V batteries contain environmentally hazardous materials.
– Do not dispose of 12 V batteries as household waste.
– Dispose of 12 V batteries at a collection point for used batteries.
Note
Environmental hazard Hazardous substances cause environmental damage.
– Dispose of oils, grease, filters, fuel, cleaning agents, brake fluid, etc., correctly and in compliance with
the applicable regulations.
Info
Even when there is no load on the 12-V battery, it discharges steadily each day.
The charging level and the method of charging are very important for the service life of the 12-V battery.
Rapid recharging with a high charging current shortens the service life of the battery.
If the charging current, charging voltage, and charging time are exceeded, electrolyte escapes through the
safety valves. This reduces the capacity of the 12-V battery.
If the 12-V battery is depleted from starting the vehicle repeatedly, the battery must be charged immedi-
ately.
If the 12-V battery is left in a discharged state for an extended period, it will become deeply discharged
and sulfating occurs, destroying the battery.
The 12-V battery is maintenance-free. The acid level does not have to be checked.
If the 12-V battery is not charged by the KTM battery charger, the 12-V battery must be removed for
charging. Otherwise, overvoltage may damage electronic components. Charge the 12-V battery according
to the instructions on the battery housing.
Preparatory work
– Remove the passenger seat. ( p. 102)
– Remove the front rider's seat. ( p. 102)
– Remove the 12-V battery. ( p. 132)

battery charger.
Battery charger (58429074000)
In addition, this battery charger can be used to test the open-
circuit voltage, the starting ability of the 12-V battery, and the
alternator. In addition, you cannot overcharge the 12-V battery
with this device.
