Bosch C70 charger I Operating instructions
Mode
Mode 7
24 V cold/
AGM mode
Note:
1) This charger is only valid for batteries with a battery capacity > 14 Ah.
2) The maintenance mode can be used to maintain the battery voltage if the battery is
not used for an extended period of time.
3) For regeneration mode, make sure that all connections between the battery and the
vehicle electrical system are disconnected.
4) For certain vehicles, it is important not to disconnect the vehicle electronics from
the power supply when changing the battery. In such cases, the power supply mode
can be used to supply power to the vehicle electronics during battery replacement.
If the load voltage is below 7.5 V, the charger will switch to standby mode. There is no
reverse polarity protection in this mode.
4.1 Pulse charging
This is an automatic charging function that cannot be selected manually.
◾ Modes 1 & 2:
If the battery voltage is between 7.5 V (± 0.5 V) and 10.5 V (± 0.5 V) at the start of
the charging process, the charger will automatically switch to pulse charging.
◾ Modes 6 & 7:
If the battery voltage is between 16 V (± 0.5 V) and 21 V (± 0.5 V) at the start of the
charging process, the charger will automatically switch to pulse charging.
4.2 Trickle charging phase
The charger has an automatic trickle charging phase with max. 800 mA at full charge.
4.3 Maintenance phase
When the battery is fully charged, "100%" LED lights up. The charger will start the
maintenance phase to keep the battery capacity in full condition.
4.4 Memory function
If the charger is disconnected from the mains during the charging process, the device
saves the previously selected mode. When reconnected to the mains and with the same
battery type (12V or 24V), the device will automatically start in the last mode.
Caution: If the connected battery type is different from the last one used (e.g. if you
were in cold/AGM mode last time and you need to connect a normal lead-acid battery
this time), please reselect the mode manually to avoid overcharging or damage.
There is no memory function for mode 3 (maintenance mode), mode 4 (regeneration
mode) & mode 5 (power supply mode).
4.5 Battery detection
Once the charger is connected to a 14.6 V - 21 V battery, 12 V & 24 V LEDs will flash al-
