English–10Bosch eBike Systems 0 276 001 Y45 | (12.10.12)To insert the rack-type battery pack 20, slide it with thecontacts facing ahead until it engages in the holder 19 of therear rack/carrier.Check if the battery pack is tightly seated. Always lock thebattery pack with lock 24, as otherwise the lock can open andthe battery pack could fall out of the holder.After locking, always remove the key 23 from the lock 24.This prevents the key from falling out and the battery packfrom being removed from unauthorised persons when theeBike is parked.To remove the standard battery pack 26, switch it off andunlock the lock with the key 23. Pivot the battery pack out ofthe upper holder 25 and pull it by the carrying strap 28 out ofthe bottom holder 27.To remove the rack-type battery pack 20, switch it off andunlock the lock with the key 23. Pull the battery pack out ofthe holder 19.OperationInitial Operation Use only original Bosch battery packs approved foryour eBike by the manufacturer. Using other batterypacks can lead to injuries and pose a fire hazard. When us-ing other battery packs, Bosch shall not assume any liabil-ity and warranty.Switching On and OffSwitching the battery pack on is one of the possibilities tostart the eBike system. Read and observe the operating in-structions of the drive unit and the drive HMI.Before switching on the battery pack or the eBike system,check that the lock 24 is locked.Note: When switching on the eBike system, the pedals of theeBike may not be subject to load, as otherwise the output ca-pacity of the drive will be limited.To switch on the battery pack, press the On/Off button 22.The LEDs of indicator 21 light up and at the same time indi-cate the charge condition.Note: When the battery-pack capacity is below 5 %, none ofthe LEDs of charge-control indicator 21 will light up. Only thedrive HMI will indicate if the eBike system is switched on.To switch off the battery pack, press the On/Off button 22again. The LEDs of indicator 21 go out. This also switches offthe eBike system.When no power output of the eBike drive is requested for ap-prox. 10 minutes (e. g., because the eBike is parked) and nobutton of the drive HMI or operating unit is pressed, the eBikesystem and thus the battery pack automatically switch off tosave energy.The battery pack is protected against deep discharging, over-charging, overheating and short-circuiting through the “Elec-tronic Cell Protection (ECP)”. In case of hazardous situations,a protective circuit automatically switches off the batterypack.When a defect of the batterypack is detected, two LEDs ofthe charge-control indicator 21flash. In this case, please referto an authorised bicycle dealer.Notes for Optimum Handling of the Battery PackThe battery-pack life can be prolonged when being properlymaintained and especially when being operated and stored atthe right temperatures.With increasing age, however, the battery-pack capacity willdiminish, even when properly maintained.A significantly reduced operating period after charging indi-cates that the battery pack is worn out and must be replaced.You can replace the battery pack yourself.In case the carrying strap 28 of the standard battery packshould be defective, please have it replaced by a bicycle deal-er.Recharging the Battery Pack prior to and during StorageWhen not using the battery pack for a longer period, charge itto approx. 60 % (3 to 4 LEDs lit on the charge-control indica-tor 21).Check the charge condition after 6 months. When only oneLED of the charge-control indicator 21 lights up, recharge thebattery pack again approx. 60 %.Note: When the battery pack is stored discharged (empty) forlonger periods, it can become damaged despite the low self-discharging and the battery-pack capacity may be strongly re-duced.It is not recommended to have the battery pack connectedpermanently to the charger.Storage ConditionsStore the battery pack in a dry, well-ventilated location. Pro-tect the battery pack against moisture and water. Under unfa-vourable weather conditions, it is recommended e. g. to re-move the battery pack from the eBike and store it in anenclosed location until being used again.The battery pack can be stored at temperatures between–10 °C and +60 °C. For a long battery-pack life, however,storing the battery pack at a room temperature of approx.20 °C is of advantage.Take care that the maximal storage temperature is not ex-ceeded. As an example, do not leave the battery pack in a ve-hicle in summer and store it out of direct sunlight.
