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.

Store these instructions in a safe place.
Only use the charger if you can fully evaluate all functions and carry them out without restrictions, or if you have received corresponding instructions.

This charger is not intended for use by children or persons with physical, sensory or mental limitations or a lack of experience or knowledge. This charger can be used by children aged 8 or older and by persons who have physical, sensory or mental limitations or a lack of experience or knowledge if a person responsible for their safety supervises them or has instructed them in the safe operation of the charger and they understand the associated dangers. Otherwise, there is a risk of operating errors and injuries.
Supervise children during use, cleaning and maintenance. This will ensure that children do not play with the charger.
u Only charge Bosch Li-ion batteries or batteries of AMPShare partners with a capacity of 1.3 Ah or more. The battery voltage must match the battery charging voltage of the charger. Do not charge any non-re-chargeable batteries. Otherwise there is a risk of fire and explosion.

Only use the charger in enclosed spaces and do not expose it to wet conditions. Water entering a charger in-creases the risk of electric shock.

Keep the charger clean. Dirt poses a risk of electric shock.
Always check the charge, including the cable and plug, before use. Stop using the charger if you discover any damage. Do not open the charger yourself, and have it repaired only by Bosch or by an authorised after-sales service centre using only original replacement parts. Damaged chargers, cables and plugs increase the risk of electric shock.
Do not operate the charger on an easily ignited surface (e.g. paper, textiles, etc.) or in a flammable environment. There is a risk of fire due to the charger heating up during operation.
Do not cover the ventilation slots of the charger. Otherwise, the charger may overheat and no long function properly.
Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.u In case of damage and improper use of the battery, vapors may also be emitted. Ensure the area is well-ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.
Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

Charging process

Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the charger.

Ensure that the charging bay (1) and the battery contacts are free of coarse dirt. Ensure that the battery is fully inserted.
The charging process begins as soon as the mains plug for the charger is inserted into the mains socket and the battery is inserted into the charging bay (1).
The charging process is only possible when the temperature of the battery is within the permitted charging temperature range (0–45 °C).

Thanks to the intelligent charging process, the state of charge of the battery is automatically detected and then charged up with the optimal charge current depending on battery temperature and voltage.
In this way, the battery is treated with care and remains permanently fully charged when it is stored in the battery charger.
A significantly reduced operating time after charging indicates that the battery has deteriorated and must be replaced.
When the charger is used continuously, or for several consecutive charge cycles without interruption, the charger may heat up. This is, however, harmless and does not indicate that the charger has a technical defect.

What the display elements mean
Flashing light battery charge indicator

The rapid charging procedure is indicated by the quick flashing of the green battery charge indicator (3).
The battery can be removed at any time and used.

Once approx. 80% of the battery capacity has been reached, the flashing of the green battery charge indicator will slow down. The rapid-charging process is now completed. If the battery remains in the charger, the charging process will be performed at a slower pace.

Continuous light green battery charge indicator
The continuous light of the green battery charge indicator (3) signals that the battery is fully charged. The battery can then be removed for immediate use.
When there is no battery connected, the continuous light of the battery charge indicator (3) signals that the mains plug is plugged into the plug socket and that the charger is ready to be used.
Continuous light red temperature monitoring indicator
The continuous light of the red indicator (2) signals that the temperature of the battery is outside of the permitted charging temperature range (0–45 °C). The charging process begins as soon as the permitted temperature range has been reached.
Flashing light red error indicator
The flashing light of the red indicator (2) signals that the charging process has been interrupted by a different fault (see “Battery is not being charged”, page 7).

Wall mounting
Pull the plug out of the socket before carrying out any work on the charger.

The charger can be used either free-standing (for use on a desktop) or mounted on the wall.
When affixing to the wall: Drill 2 holes, leaving a clearance of 72 mm. To secure it, use round-head screws with a diameter of 5 mm to max. 6.5 mm.

Troubleshooting

Battery is not being charged

Battery is not being charged and the red temperature monitoring/error indicator (2) is flashing red.

Cause: The charger has identified an internal error.
Corrective measure: Ensure that all batteries are fully inserted. Remove the mains plug and reinsert. If the error occurs again, have the charger checked by an authorised after-sales service centre for Bosch power tools.
Cause: Battery is not correctly inserted.
Corrective measure: Insert the battery into the charger correctly.
Cause: The battery contacts and charging contacts are dirty.
Corrective measure: Clean the battery contacts and charging contacts; e.g. by inserting and removing the battery several times.
Cause: Battery defective
Corrective measure: Replace the battery.

Battery is not being charged and the indicator (2) is lit up red.

Cause: Battery temperature is outside of the charging range
Corrective measure: Wait until the battery temperature is back within the permitted charging temperature range (0–45 °C).
Indicators do not light up
None of the indicators are lighting up, battery will not be charged.
Cause: Plug socket, mains cable or battery charger defective
Corrective measure: Check the mains voltage. If necessary, have the charger checked by an authorised after-sales service centre.
Cause: Mains plug of the battery charger is not (correctly) plugged in
Corrective measure: Plug the mains plug (fully) into the plug socket.
