BOSCH Ni-Cd 12V How should the battery terminals be connected?

Thanks for this explanation, so I deduce that the size of the resistance also counts .... That is, if the manufacturer provides a 1/4 watt resistor this cannot be replaced by a similar 1/8 watt right?

In theory ... there is one identical resistance at the charger PCB.
In theory ... detection is made by the two resistors acting as resistance divider (both they are set in parallel mode)  and as such their total value will become half.
In theory ...  the smart IC will get this compliance information and start charging.

In your case, you have the smallest available charger, and there is no clear answers of what it does apply for it or not.
If the charger it does recognize the battery pack and charging it, then do not buy any resistors.

Thanks a lot for the explanation, I learned a lot, I will do as you suggest.
