IMPORTANT NOTICE

• Contact the place of purchase or a bicycle dealer for information on installation and adjustment
of the products which are not found in the user's manual. A dealer's manual for professional
and experienced bicycle mechanics is available on our website (https://si.shimano.com).

• Do not disassemble or alter this product.

For safety, be sure to read this user's manual thoroughly
before use, and follow it for correct use.

Important Safety Information

For replacement information, contact the place of purchase or a bicycle dealer.

Be sure to observe the following in order to avoid burns or other injury from fluid
leakages, overheating, fire or explosions.

DANGER

• Use the dedicated charger to charge the battery. If any non-specified items are used, fire,
overheating or leakages may occur.
Refer to “Product Lineup” on our website (https://productinfo.shimano.com) for details about
compatible battery chargers.

• Use an AC adapter with a USB port with a voltage of 5.0 Vdc and with a current equal to or
higher than 1.0 Adc. If the one with a current lower than 1.0 A is used, the AC adapter may
heat up, potentially causing a fire, smoke, heating, destruction, electric shock, or burns.

• Do not heat the battery or throw it into fire. If this is not observed, fire or bursting may
occur.

• Do not use or leave the battery in hot and humid places such as where the battery is exposed to
direct sunlight, in a closed vehicle on a hot day, or near a heater. If this is not observed,
leakages, overheating or bursting may cause fire, burns or other injury to occur.

• Do not disassemble or modify the battery or apply solder directly to the battery terminals.
If this is not observed, leakages, overheating or bursting may cause fire, burns or other
injury to occur.

• Do not connect the (+) and (-) terminals with metallic objects. Do not carry or store the battery
together with metallic objects such as necklaces or hairpins. If this is not observed, short-circuits,
overheating, burns or other injury may occur.

• If any liquid leaking from the battery gets into the eyes, immediately wash the affected area
with clean water without rubbing the eyes, and then seek medical advice. If this is not done,
blindness may occur.

WARNING

• If the battery does not become fully charged after 4 hours of charging, stop charging.

• Do not place the battery into fresh water or sea water, and do not allow the battery terminals
to get wet. If this is not observed, fire, bursting or overheating may occur.

• The operating temperature ranges for the battery are given below. Do not use the battery in
temperatures outside these ranges. If the battery is used or stored in temperatures which are
outside these ranges, fire, injury or problems with operation may occur.

1. During discharge: –10 °C - 50 °C

2. During charging: 0 °C - 45 °C

• Do not subject this battery to extremely low air pressure. Doing so may result in an explosion of
the battery or the leakage of flammable liquid or gas from it. Transporting this battery by air is
not a problem.

• Do not use the battery if it has any noticeable scratching or other external damage. If this is not
observed, bursting, overheating or problems with operation may occur.

• Do not subject the battery to strong shocks or throw it. 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.

User's Manual

• If any leaked fluid gets on your skin or clothes, wash it off immediately with clean water. The
leaked fluid may damage the skin.

• After reading the user's manual carefully, keep it in a safe place for later reference.

CAUTION

• Observe all federal, state and local environmental regulations when disposing of this battery.
Disposal of this battery into fire or a furnace, or mechanically crushing or cutting it can result in
an explosion of the battery.

• Keep away from children.

Notice

• If the unit will not be used for an extended period, store it after charging in cool indoor places
(approx. 10 to 20 °C) where the battery will not be exposed to direct sunlight or rain.

• Also read the user's manual included with the battery charger.

• 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.

Regular inspections before riding the bicycle

Before riding the bicycle, check the following items. If any problems are found with the following
items, contact the place of purchase or a bicycle dealer.

• Does the battery require charging?

• Is the battery securely installed to the frame?

• Are the electric wires installed correctly?

• Are the dummy plugs correctly attached to any unused E-TUBE ports?

Operation

 Connecting the electric wire

• Use a dedicated tool to remove the dummy plugs from the E-TUBE port and connect the electric
wires.

• When using the product, be sure to connect the electric wires to the center E-TUBE port. The
product will not operate normally if nothing is connected to the center E-TUBE port.

(Always connect the electric wire during use)

Electric wire
EW-SD300

Dummy plug

E-TUBE port

• Be sure to attach the dummy plugs to any E-TUBE ports that do not have electric wires
connected to them.
The product will not operate normally if the dummy plugs are not attached.

 Guide to charging time

The charging time of an AC adapter with a USB port is about 1.5 hours, and that of computer USB
port type about 3 hours.
(Note that the actual time will vary depending on the amount of charge remaining in the battery.
Depending on the specifications of the AC adapter, recharging via the AC adapter requires as
many hours (about 3 hours) as recharging via PC.)
This battery is of lithium ion type. Use the designated charger. For information on how to charge
the battery, follow the user's manual included with the charger.

 Storing the battery

• Dummy plugs are installed at the time of shipment from the factory. Do not remove them
except when necessary.

• If storing the battery away for a long period, do so with the battery level at 50% or higher, and
charge the battery once every six months. Refer to the battery charger user's manual for details
about battery levels.

• Store the battery or bicycles with the battery installed in cool indoor places (approx. 10 to 20
°C) where they do not become exposed to direct sunlight or rain. If the storage temperature is
low or high, the performance of the battery is reduced, and its available time will be shorter.
When you use the battery after a long storage period, be sure to fully charge it before use.

 About system power reset

When the system fails to operate, it may be recovered by resetting the system power.

• In some cases, the system can be recovered using E-TUBE PROJECT. Refer to the user's manual
for E-TUBE PROJECT for details on this procedure.

• If you are unable to recover the system using the E-TUBE PROJECT reset procedures, remove all
electric wires and dummy plugs connected to the battery, wait approximately one minute, and
then reinsert the electric wires and dummy plugs.

• If neither of these procedures recovers the system, contact the place of purchase.

 Battery life

• The battery is a consumable item. The battery will gradually lose its capacity for charging after
repeated use and after time has passed. If the length of time that the battery can be used
becomes 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.

 About used batteries

Lithium ion batteries are recyclable, valuable resources.
For information on used batteries, contact the place of purchase or a bicycle dealer.
