BATTERY PACK AND CHARGING PROCEDURE
The battery pack equipped for the Yamaha e-Bike Sys-
tems is a lithium-ion battery. The lithium-ion battery is
lightweight and offers superior capacity. However, it does
have the following characteristics.
• Its performance decreases in extremely hot or cold en-
vironments.
• It naturally loses its charge.
• It is necessary to use it several times before its perfor-
mance stabilizes.
The battery pack for the Yamaha e-Bike Systems also has
an embedded computer which notifies you of estimated
residual battery capacity and suspected faults via the bat-
tery capacity indicator lamp.
By pressing the battery capacity indicator button, you can
display the residual battery capacity for approximately 5
seconds.
See “CHECKING THE RESIDUAL BATTERY CAPACITY”
for the estimate of the residual battery capacity. See
“TROUBLESHOOTING” for information on fault flashing.

BATTERY PACK AND CHARGING PROCEDURE
Appropriate charging environments
For safe and efficient charging, use the battery charger in
a location that is:
• Flat and stable (when on the bicycle)
• Free of rain or moisture
• Out of direct sunlight
• Well-ventilated and dry
• Not accessible to children or pets
• Temperature between 15–25 °C
Inappropriate charging environments and
solutions.
The hot and cold environments described below can
cause charging to enter standby or suspension without
fully charging the battery.
• Summertime charging standby/suspension
If charging in a location receiving direct summer sun-
light or immediately after riding, the battery charger
might enter charging standby (all four battery capacity
indicator lamps flash slowly). See “ Reading the charg-
ing status”. This is to automatically stop charging in or-
der to protect the battery from exceeding the specified
temperature while charging. You can avoid charging
suspension by starting to charge with the battery cold
or at a room temperature of 15–25 °C. If charging sus-
pension occurs, move the battery charger to a cool lo-
cation to reduce the charging standby time.
• Wintertime charging standby/suspension
Charging standby will occur if the temperature is 0 °C
lower. If charging is started and the temperature drops
below this level due to late-night cooling or other fac-
tors, charging is suspended and standby mode is en-
tered to protect the battery. In such cases, restart
charging at an indoor location with a temperature of
15–25 °C.
• Noise on televisions/radios/computers
Charging next to televisions, radios, or similar appli-
ances might cause static, flickering images, and other
interference. If this occurs, recharge in a location fur-
ther away from the television or radio (such as in an-
other room).
