Safety instructions

Read all the safety and general instructions.
Failure to observe the safety and general instructions may result in electric shock, fire and/or serious injury.
The contents of lithium-ion battery cells are flammable under certain conditions. You must therefore ensure that you have read and understood the rules of conduct set out in these operating instructions.

Save all safety warnings and instructions for future reference.
The term battery is used in these instructions to mean all original Bosch eBike rechargeable battery packs.

• Remove the battery from the eBike before beginning
  work (e.g. inspection, repair, assembly, maintenance,
  work on the chain, etc.) on the eBike, transporting it with a car or airplane, or storing it. Unintentional activation of the eBike system poses a risk of injury.

• Do not open the battery. There is a risk of short-circuiting. Opening the battery voids any and all warranty claims.

• Protect the battery against heat (e.g. prolonged sun exposure), fire and from being submerged in water.
  Do not store or operate the battery near hot or flammable objects. There is a risk of explosion.

• When the battery is not in use, keep it away from paper clips, coins, keys, nails, screws or other small metal objects that could make a connection from one terminal to another. A short circuit between the battery terminals may cause burns or a fire. Short circuit damage which occurs in this instance voids any and all warranty claims against Bosch.

• Avoid mechanical loads and exposure to high temperatures. These can damage the battery cells and cause the flammable contents to leak out.

• Do not place the charger or the battery near flammable materials. Ensure the battery is completely dry and placed on a fireproof surface before charging.
  There is a risk of fire due to the heat generated during charging.

• The eBike battery must not be left unattended while charging.

• If used incorrectly, liquid may leak from the battery.
  Contact with this liquid should be avoided. If contact occurs, rinse off with water. If the liquid comes into contact with your eyes, seek additional medical attention. Liquid leaking from the battery may cause irritation or scalding.

• Batteries must not be subjected to mechanical shock.
  There is a risk of the battery being damaged.

• The battery may give off fumes if it becomes damaged or is used incorrectly. Ensure the area is well ventilated and seek medical attention should you experience any adverse
  effects. The fumes may irritate the respiratory system.

• Only charge the battery using original Bosch chargers.
  When using chargers that are not made by Bosch, the risk of fire cannot be excluded.

• Use the battery only in conjunction with eBikes that have original Bosch eBike drive systems. This is the only way in which you can protect the battery against dangerous overload.

• Use only original Bosch batteries that the manufacturer has approved for your eBike. Using other batteries can lead to injuries and pose a fire hazard. Bosch accepts no liability or warranty claims if other batteries are used.

• Keep the battery away from children.

• Read and observe the safety warnings and directions contained in all the eBike system operating instructions and in the operating instructions of your eBike.
  The safety of both our customers and our products is important to us. Our eBike batteries are lithium-ion batteries that have been developed and manufactured in accordance with the latest technology. We comply with or exceed the requirements of all relevant safety standards. When charged, these
  lithium-ion batteries contain a high level of energy. If a fault occurs (which may not be detectable from the outside), in very rare cases and under unfavorable conditions,
  lithium-ion batteries can catch fire.

Privacy notice
When you connect the eBike to the Bosch DiagnosticTool 3, data about the eBike batteries (e.g. temperature, cell voltage, etc.) is transferred to Bosch eBike Systems (Robert Bosch GmbH) for the purposes of product improvement. You can find more information about this on the Bosch eBike website at www.bosch- ebike.com.

Technical data

Fitting

• Ensure the battery is placed on clean surfaces only.
  Avoid getting dirt, e.g. sand or soil, in the charging socket and contacts in particular.

Testing the battery before using it for the first time
Test the battery before charging it for the first time or using it in your eBike.
To do this, press the on/off button (7) to switch the battery on. If none of the LEDs on the battery charge indicator (6) light up, the battery may be damaged.
If at least one (but not all) of the LEDs on the battery charge indicator (6) lights up, the battery will need to be fully charged before using it for the first time.

• Do not charge or use batteries if they are damaged. Contact an authorized bicycle dealer.
  Charging the battery

• A Bosch eBike battery must only be charged using an original Bosch eBike charger.

Note: The battery is supplied partially charged. To ensure full battery capacity, fully charge the battery in the charger before using it for the first time. To charge the battery, read and follow the instructions in the operating manual for the charger. The battery can be charged at any state of charge. Interrupting the charging process does not damage the
battery. The battery has a temperature monitoring function which only allows it to be charged within a temperature range of 0 °C to 40 °C.
If the temperature of the battery is outside this charging range, three of the LEDs on the battery charge indicator (6) will flash. Disconnect the battery from the charger and
let it acclimatize. Do not reconnect the battery to the charger until it has reached the correct charging temperature.
Battery charge indicator
The five green LEDs on the battery charge indicator (6) indicate the battery’s state of charge of when the battery is switched on.
Each LED represents approximately 20 % of the charging capacity. When the battery is fully charged, all five LEDs will be lit.
The battery’s state of charge when switched on is also shown on the display of the onboard computer. Read and follow the instructions in the operating manuals for the drive unit and onboard computer.
If the battery capacity is less than 5 %, all the LEDs on the battery charge indicator (6) on the battery will go out.
The display function of the onboard computer, however, will carry on working.
Once charging is complete, disconnect the battery from the charger and the charger from the mains.

Operation

Start-up
u Use only original Bosch batteries that the manufacturer has approved for your eBike. Using other batteries can lead to injuries and pose a fire hazard. Bosch accepts no liability or warranty claims if other batteries are used.
Switching on/off
Switching on the battery is one way to switch on the eBike system. Read and follow the instructions in the operating manuals for the drive unit and on- board computer.
Before switching on the battery, i.e. the eBike system, make sure that the lock (2) is closed.
To switch on the battery, press the on/off button (7). Do not use any sharp or pointed objects to press the button. The
LEDs on the indicator (6) will light up, indicating the battery’s state of charge at the same time.
Note: If the battery capacity is less than 5 %, none of the LEDs on the battery charge indicator (6) will light up.
Whether the eBike system is switched on is only visible on the onboard computer/control unit.
To switch off the battery, press the on/off button  (7)again.
The LEDs on the indicator (6) will go out. This will also switch the eBike system off.
If no power is drawn from the eBike drive for about 10 minutes (e.g. because the eBike is not moving) and no button is pressed on the on-board computer or the control unit of the eBike, the eBike system will switch off automatically.
The battery is protected against deep discharge, overloading, overheating and short-circuiting by the “Electronic Cell
Protection (ECP)”. In the event of danger, a protective circuit switches the battery off automatically.

If a fault is detected in the battery, two of the LEDs on the battery charge indicator (6) will flash. Contact an authorised bicycle dealer if this happens.
Recommendations for optimal handling of the battery
The service life of the battery can be extended if it is looked after well and especially if it is stored at the correct temperature. As it ages, however, the capacity of the battery will
diminish, even with good care.
A significantly reduced operating time after charging indicates that the battery has deteriorated. You can replace the battery.
Recharging the battery before and during storage
When you are not going to use the battery for an extended period (longer than three months), store it at a state of charge of around 30 % to 60 % (when two to three of the
LEDs on the battery charge indicator (6) are lit). Check the state of charge after six months. If only one of the LEDs on the battery charge indicator (6) is lit, charge the battery back up to around 30 % to 60 %.
Note: If the battery is stored with no charge for an extended period of time, it may become damaged despite the low self-discharge and the battery capacity could be significantly reduced. Leaving the battery permanently connected to the charger isnot recommended.

Storage conditions
If possible, store the battery in a dry, well-ventilated place.
Protect it against moisture and water. When the weather conditions are bad, it is advisable to remove the battery from the eBike and store it in a closed room until you use it next, for example.
Store the eBike batteries in the following locations:
– In a room with a smoke alarm
– Away from combustible or easily flammable objects
– Away from heat sources
To ensure an optimum service life, store the eBike batteries at temperatures between 10 °C and 20 °C. Never store them at temperatures below –10 °C or above 60 °C.
Make sure that the maximum storage temperature is not exceeded. Do not leave the battery in your car in the summer,
for example, and store it away from direct sunlight.
Leaving the battery on the bicycle for storage is not recommended.
Action in the event of a fault
The Bosch eBike rechargeable battery must not be opened, including for repairs. There is a risk of the Bosch eBike rechargeable battery catching fire, e.g. as a result of a short
circuit. This risk continues to apply on any Bosch eBike rechargeable battery ever opened, even at a later point in time.
In the event of a fault, do not have your Bosch eBike rechargeable battery repaired; instead, have it replaced with an original Bosch eBike rechargeable battery by your specialist
retailer.

Maintenance and servicing

Transport

u If you transport your eBike attached to the outside of your car, e.g. on a bike rack, remove the on-board computer and the eBike battery to avoid damaging them.
The batteries are subject to legislation on the transport of dangerous goods. Private users can transport undamaged batteries by road without having to comply with additional
requirements.
When batteries are transported by commercial users or third parties (e.g. air transport or forwarding agency), special requirements on packaging and labelling (e.g. ADR regulations) must be met. When preparing items for shipping, a dangerous goods expert can be consulted as required.
Do not ship batteries if the housing is damaged or the rechargeable battery is not fully functional. Use only the original Bosch packaging for transport. Apply tape over
exposed contacts and pack the battery such that it cannot move around inside the packaging. Inform your parcel service that the package contains dangerous goods. Please
also observe any additional national regulations should these exist.
If you have any questions about transporting the batteries, contact an authorised bicycle dealer. You can also order suitable transport packaging from the dealer.

Disposal

Batteries, accessories and packaging should be recycled in an environmentally friendly manner.
Do not dispose of batteries along with the household waste.
Apply tape over the contact surfaces of the battery terminals before disposing of batteries.
Do not touch severely damaged eBike batteries with your bare hands – electrolytes may escape and cause skin irritation. Store the defective battery in a safe location outdoors.
Cover the terminals if necessary and inform your dealer.
They will help you to dispose of it properly.
In accordance with Directive 2012/19/EU and Directive 2006/66/EC respectively, electronic devices that are no longer usable and defective/drained batteries must be
collected separately and recycled in an environmentally friendly manner.
