| Question abot a battery charger |
| (1/2) > >> |

I have a Sony BC-CS2A charger. Actually 2 of them. I can't find a manual for it and was wondering if it takes anywhere between 1 and 4 batteries at the same time. I have not tried mixing AA and AAAs and the same time. I am not sure they fit physically. This charger will error if it thinks the battery has an issue. I was wondering if in general battery chargers are designed to accept any number of batteries at the same time? In this schematic I can only find 2 places that look they are the application voltages in the upper right I think it is 5.4 and 2.1 volts. |

Wow, that is roughly 10x more complicated than it needs to be... but it looks like it has two channels. |

The diagram clearly shows 2 separate channels of the current supplier, but one current sensor. Apparently, the charge occurs separately, and the current sensor is used as a common indicator. Charging AA+AAA, I think, is quite possible. The principle of charging 1 battery or 2, connected in parallel - only a matter of choosing the current or time at constant current. |

Thanks for the information. According to the diagram though are the 2 channels not connected together around on top of Q210? So perhaps basically 2 wires go to all the batteries in parallel? 2 channels would just double the current? Oh maybe it is a ground completed circuit under Q203 (negative battery terminal)? You probably wouldn't depict that with a ground symbol. |
