About the battery Lithium-ion (Li-ion) battery
The Li-ion battery used in the EC-03
features high energy density and has a
high voltage (approximately three times
that of nickel-cadmium (Ni-Cd) or nick-
el-hydrogen (Ni-MH) batteries), mean-
ing it can be made both compact and
lightweight.
Nickel-cadmium and nickel-hydrogen
batteries have a memory effect that
causes electric output capacity to de-
crease as a result of repeated partial
discharging and charging, so that they
need to have to be completely dis-
charged periodically. Li-ion batteries
can be repeatedly partially charged
without requiring fully discharging.TIP
It is not necessary to use up the
battery before charging.

The electric output capacity de-
creases over time and use, but the
rate at which it depletes depends
on condition of use.

The battery discharge may vary
depending on the ambient temper-ature. At low temperatures, the
traveling distance on a single
charge is reduced compared with
normal temperatures and charging
also takes longer. At low tempera-
tures, the electric output capacity
decreases, compared with normal
temperatures, and traveling dis-
tance on a single charge is re-
duced, but this is normal.

Storing the vehicle in an extremely
hot or cold place could decrease
the electric output capacity.

Even if the battery is not used, thebattery discharges gradually.
Recycling the battery
Li-ion batteries can be recycled. If the
electric output capacity decreases ex-
cessively due to depletion, have a
Yamaha dealer replace the battery. Al-
ways follow local regulations regarding
the disposal of batteries.

Braking
WARNING
EWA10300

Avoid braking hard or suddenly
(especially when leaning over to
one side), otherwise the scooter
may skid or overturn.

Railroad crossings, streetcar
rails, iron plates on road con-
struction sites, and manhole
covers become extremely slip-
pery when wet. Therefore, slow
down when approaching such
areas and cross them with cau-
tion.

Keep in mind that braking on a
wet road is much more difficult.

Ride slowly down a hill, as brak-
ing downhill can be very diffi-cult.
1. Close the accelerator grip com- pletely.
2. Apply both front and rear brakes simultaneously while gradually in-
creasing the pressure. Front
