I'm a little confused by the pictures. I would like to charge an older Bosch battery with a new Standard 4 charger (EB12.110.001). So far I have done this with the 36-4/230 charger. Unfortunately, the designations are not quite clear to me.
The "mother piece" in the illustration seems to fit. But doesn't the father piece fit the bike?

Accepted Answer

The "mother piece" fits onto the charger cable (see Fig. 3). The "father piece" fits onto the battery of the previous generation (e.g. Bosch eBike PowerPack 400 Classic+). This works very well - we only need one charger for 2 battery generations.
