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. ( p. 145)
– Remove the front rider's seat. ( p. 146)
– Disconnect negative cable of the 12-V battery to avoid damage
to the onboard electronics.
