KTM 890 Duke R - Owner's Manual > Charging the 12-V battery

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, or charging time is 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 immediately.

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.

Main work

• Disconnect negative cable 1 of the 12-V battery to avoid damaging the onboard electronics.
