DANGER
WARNING
CAUTION
Important safety information
Consult your place of purchase or a distributor regarding
items requiring replacement.
Be sure to observe the following instructions in order to
avoid burns or other injury from fluid leakage,
overheating, fire, or explosion.
DANGER
•Use the specified battery charger for charging and observe the specified
charging conditions. Doing otherwise may cause overheating, bursting,
or ignition.
Do not leave the battery near sources of heat such as heaters, and
•
do not heat the battery or throw it into a fire. Doing so may cause
bursting or ignition.
Do not deform, modify, disassemble, or apply solder directly to the
•
battery. Doing so may cause leakage, overheating, bursting, or
ignition.
•Do not connect the terminals with metallic objects. If this is not
observed, short-circuits or overheating may occur, resulting in burns or
other injury.
•Do not carry or store the battery together with metallic objects such as
necklaces or hairpins. If this is not observed, short-circuits or
overheating may occur, resulting in burns or other injury.
•Do not place the battery into fresh water or sea water, and do not
allow the battery terminals to get wet. Doing so may cause overheating,
bursting, or ignition.
•Do not throw or subject the battery to strong shock. Doing so may
cause overheating, bursting, or ignition.
•If the battery does not become fully charged even two hours after the
designated charging time, immediately unplug the battery from the
electrical outlet and contact the place of purchase. Doing otherwise
may cause overheating, bursting, or ignition.
Failure to follow the instructions will result
in death or serious injury.
Failure to follow the instructions could
result in death or serious injury.
Failure to follow the instructions could
cause personal injury or physical damage
to equipment and surroundings.
WARNING
•Do not disassemble or modify the product. This may cause the product
to not operate correctly, and you may suddenly fall and be seriously
injured.
•If any liquid leaking from the battery gets into your eyes, immediately
wash the affected area thoroughly with clean water such as tap water
without rubbing your eyes, and seek medical attention immediately. If
this is not done, the battery liquid may damage your eyes.
•Do not use it outside of the operating temperature ranges of the
battery. If a battery is used or stored in temperatures which are outside
these ranges, fire, injury or problems with operation may occur.
1. During discharge: -10 - 50°C
2. During charging: 0 - 40°C
•Do not use the battery if it has any noticeable scratches or other
external damage. If this is not observed, bursting, overheating or
problems with operation may occur.
•Do not use the battery if leakages, discoloration, deformation, or any
other abnormalities occur. If this is not observed, bursting, overheating
or problems with operation may occur.
•Do not recharge the battery in wet or very humid places, or outdoors. A
fire, ignition, overheating, or electric shock may occur.
•Do not insert or remove the plug while it is wet. Doing so may result in
electric shock. If the inside of the plug is wet, dry it thoroughly before
inserting it.
CAUTION
•Do not leave the battery in a place exposed to direct sunlight, inside a
vehicle on a hot day, or other hot places. This may result in battery
leakage.
•If any leaked fluid gets on your skin or clothes, wash it off immediately
with clean water. The leaked fluid may damage your skin.
•Keep away from children.
•Handle components with both hands. Failure to do so may cause the
components to fall and break or cause injury.
•If an error occurs during the battery discharge or charge operation,
immediately stop using it and check the user's manual. If you are not
sure, consult the place of purchase or a distributor.
•
Do not touch the battery when it is at a high temperature. Doing
so may cause a burn.
•Avoid touching the battery for an extended period of time when its
temperature has increased. Doing so may cause a low-temperature
burn.
Notice
•Charging can be carried out at any time, regardless of the remaining
battery, but please fully charge the battery in the following cases. Be
sure to use the dedicated battery charger.
– The battery cannot be used at the time of purchase. Before riding, be
sure to fully charge the battery.
– When the battery is completely depleted, charge it as soon as
possible. If you leave the battery without charging it, the battery will
deteriorate and may become unable to be used.
•Wait a while before pressing the power button when turning the power
ON again after the power has been turned OFF.
•Before connecting the battery, make sure that the area where the
battery will be connected (terminal) is dry and not dirty.
•Press the battery power button and if the LED display does not light up,
the protective circuit is operating. Connect the battery charger and
charge the battery to deactivate this.
•If the battery is charged in a low-temperature environment of 5°C or
lower, the traveling distance of a full charge will be shorter. Also, if the
battery is used in a low-temperature environment of 5°C or lower, the
battery consumption will become quicker. This is due to the
characteristics of the battery, and the battery will return to normal
when at a normal temperature.
•Riding with a high level of assistance in a low-temperature environment
when the battery level is low may cause the battery level to drop to 0%,
due to the characteristics of the battery. Charge it before use.
•Make sure to also refer to the battery charger user's manual.
•Products are not guaranteed against natural wear and deterioration
from normal use and aging.
•For maximum performance we highly recommend SHIMANO lubricants
and maintenance products.
This device complies with part 15 of the FCC Rules. Operation is subject
to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device

Introduction
You cannot use the battery immediately after shipment. The battery can
be used after charging it with the designated battery charger. Be sure to
charge it before use. The battery can be used when the LED on it turns
on.
Regular inspections before riding the bicycle
Before riding the bicycle, check the following items. If any problems are
found, consult your place of purchase or a distributor.
•Is the battery level sufficient?
•Is the battery installed correctly?
Handling method
Charging time
The charging time will vary depending on the battery level and the
battery charger being used. Refer to the battery charger user's manual for
the designated charging time. This is a lithium-ion battery. Use the
dedicated battery charger designated by SHIMANO. For the charging
method, follow the user's manual for the battery charger.
Battery storage method
•If the bicycle will not be ridden for an extended period, store it with a
battery level of approximately 70%. Also, charge the battery once every
six months to ensure that it is not completely discharged.
•Store the battery or bicycle with battery installed in a cool indoor
location away from direct sunlight and rain (approx. 10 to 20°C). If the
storage temperature is too low or too high, the performance of the
battery is reduced, and its usable time will be shorter. When you use it
after a long storage period, make sure to charge it first.
Battery life
•The battery is an exhaustible item. The battery will gradually lose its
capacity to charging after repeated use. If the length of time that the
battery can be used and its traveling distance become extremely short,
it has probably reached the end of its life, and so you will need to
purchase a new battery.
•The life of the battery will vary depending on factors such as the
storage method, the usage conditions, the surrounding environment
and the characteristics of the individual battery pack.
Used batteries
•Lithium-ion batteries are recyclable, valuable resources. Please observe
the appropriate rules of the country, state or region regarding used
batteries. If you are not sure, consult the place of purchase or
distributor.
Disposal information for countries outside
the European Union
This symbol is only valid within the European
Union. Follow local regulations when disposing of
used batteries. If you are not sure, consult the
place of purchase or distributor.
