3.10 Recharging the battery
Warning
Risk of injury Batteries contain harmful substances.
–Keep batteries out of the reach of children.
–Keep sparks and open flames away from the batteries.
–Only charge batteries in well-ventilated rooms.
–Maintain a minimum clearance from inflammable materials when charging batteries.
Minimum clearance 1 m (3 ft)
–Do not charge deeply discharged batteries if charge is already below the minimum voltage.
Minimum voltage before the start of the charge 9 V
–Dispose of batteries with less than the minimum voltage correctly.
Note
Environmental hazard Batteries contain environmentally-hazardous materials.
–Do not dispose of batteries as household waste.
–Dispose of 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 battery, it discharges steadily.
The charging level and the method of charging are very important for the service life of the battery.
Rapid recharging with a high charging current shortens the service life of the battery.
If the charging current, charging voltage, or charging time are exceeded, the battery will be destroyed.
If the battery is depleted by repeated starting, the battery must be charged immediately.
If the battery is left in a discharged state for an extended period, it will become over-discharged and sul-
fated, destroying the battery.
The battery is maintenance-free.

–Remove the seat. ( p. 15)
