Charging The Battery; Jump Start - KTM 990 SUPER DUKE Owner's Manual

MAINTENANCE WORK ON CHASSIS AND ENGINE
VOLT

Charging the battery

The battery discharges every day, even if it is not used.
Always disconnect the battery when charging. Charge the battery as described in the instruc-
tions [1] on the battery housing. Do not exceed the amperage and charging time. Quick charg-
ing at a high amperage has an adverse effect on the service life.
Always use special charging devices to charge maintenance-free batteries, e.g. the KTM charg-
ing device (item no. 58429074000). You can also use this charging device to test the off-
load voltage and startability of the battery and generator. It is impossible to overcharge the
battery with this device.
1
Charge the battery immediately if it is empty when you start the motorcycle. If left to stand
in an uncharged condition for a longer period of time, the battery will run down and sulfa-
tize, destroying the battery.
Recharge the battery every 3 months if it is being stored for a longer period of time.
– NEVER REMOVE THE CLOSURE SINCE IT WILL BE DAMAGED.
– TO AVOID DAMAGE TO THE ON-BOARD ELECTRONIC SYSTEM, ALWAYS DISCONNECT THE
MINUS POLE BEFORE YOU CHARGE THE BATTERY.
– TO CHARGE, CONNECT THE BATTERY TO THE BATTERY CHARGER BEFORE YOU SWITCH ON
THE BATTERY CHARGER. WHEN THE BATTERY IS CHARGED, SWITCH OFF THE BATTERY
CHARGER BEFORE YOU DISCONNECT THE BATTERY.
– PROVIDE ADEQUATE VENTILATION WHEN CHARGING THE BATTERY IN A CLOSED ROOM; THE
BATTERY EMITS EXPLOSIVE GASES WHEN CHARGING.
– ELECTROLYTES WILL ESCAPE THROUGH THE SAFETY VALVES IF THE BATTERY IS CHARGED
TOO LONG OR AT AN EXCESSIVE VOLTAGE OR AMPERAGE. THIS WILL REDUCE BATTERY
CAPACITY.
– TRY TO AVOID QUICK CHARGES.
