KTM 390 Adventure - Owner's Manual > Removing 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.

Preparatory work

• Remove the passenger seat.
• Remove the front rider's seat.

Main work

• Remove screws 1 and take off the holding bracket.
• Disconnect negative cable 2 from the 12-V battery.

• Pull back positive terminal cover 3.
• Disconnect positive cable 4 from the 12-V battery.
• Unhook rubber strap 5 and open rubber strap 6.
• Pull the 12-V battery upwards and out of the battery compartment.

Info Never operate the motorcycle with a discharged 12-V battery or without a 12-V battery. In both cases, electrical components and safety devices can be damaged.

The vehicle will therefore no longer be roadworthy.

Installing the 12-V battery

Main work

• Position the 12-V battery in the battery compartment.

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.

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 by repeated starting, the 12-V 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.

Preparatory work

• Remove the passenger seat.
• Remove the front rider's seat.
• Disconnect negative cable of the 12-V battery to avoid damage to the onboard electronics.

Main work

• Connect a battery charger to the 12-V battery. Switch on the 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. It is impossible to overcharge the 12-V battery using this device.

Info Never remove cover 1.

Charge the 12-V battery to a maximum of 10 % of the capacity specified on battery housing 2.

• Switch off the battery charger after charging and disconnect from the 12-V battery.

Guideline

• Position the negative cable and mount and tighten the screw.
• Position the negative terminal cover.

Finishing work

• Mount the front rider's seat.
• Mount the passenger seat.
• Set the time and date.
