becomes 5–10% shorter when the

Effective use of
the battery If the battery is left nearly fully charged
(4–5 segments shown on the battery
charge indicator) and exposed to high
temperature for an extended period, it
will rapidly deplete. To extend the bat-
tery life, handle as follows:
Choose a cool place with no direct
sunlight when charging the bat-
tery.

Do not store the battery with a
charge less than 20% (below the
last segment of the battery level in-
dicator) for an extended period of
time.

Choose a cool and well-ventilated
place without direct sunlight for
storing the vehicle.

When not used for a long period of
time, charge the battery until the
2–3 segments of the battery
charge indicator are shown and
then store the vehicle in a cool
place (optimum temperature 15  C
– 25 C). Check the battery level
while the vehicle is in storage. If
the battery level drops to the last
segment, recharge the battery until 2–3 segments of the battery
charge indicator are shown.

If the battery is discharged until the
battery is depleted, recharging will
not be possible and the battery willnot be usable.

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.

9Battery depletion
The electric output capacity of the
Li-ion battery used in the EC-03 gradu-
ally decreases in the course of use. Al-
though the extent of depletion varies
based on the conditions of use, electric
output capacity typically decreases to
70% of a new battery when having trav-
eled 8000–10000 km for two years.
This is equivalent to charging about
500 times with the condition of riding
16–20 km on a single charge.
Battery electric output auto-stop-
ping function
The battery is equipped with a function
to prevent further use in case of exces-
sive depletion. When eight years have
passed since initial battery charging or the accumulated charging amount has
reached 14000 Ah, the battery will no
longer be usable.
TIP
When the battery is replaced with
a new one, fully charge the battery
once before using it. If the battery
is not fully charged, the battery lev-
el indicator does not show the pre-
cise battery level.

At low temperatures such as 0
C,
the electric output capacity de-
creases by approximately 20%
compared with normal tempera-
ture.

If a depleted battery is used at low
temperatures, the electric output
capacity decreases by approxi-
mately 20% compared with normaltemperatures.

der to extend the battery life, it is
recommended to charge the
battery until the battery level in-
dicator reaches a maximum of
2–3 segments. A lower or higher
charge is not recommended.

Make sure that the amount of
charge remaining in the battery
does not fall below 20% (less
than the last segment of the bat-
tery level indicator). If stored un-
der this condition for a long
period of time, the battery can
be damaged and may need to be
replaced depending on how low
the capacity is.

Once the battery is completely
depleted, it cannot be re-
charged.

After long-term storage, be sure
to recharge the battery before
using the vehicle. (It may takelonger to charge than usual.)
Before storing your scooter for several
months: 1. Follow all the instructions in the “Care” section of this chapter.
2. Lubricate all control cables and the pivoting points of all levers as well
as the centerstand.
3. Check and, if necessary, correct the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
TIPMake any necessary repairs beforestoring the scooter.
