Charging function:
The IQ312 works in a mode called „ Current Auto Set Mode “. This means, for every inserted
battery, the current is set automatically. This feature allows a simple and safe use of the charger.
The automatically chosen charging current depends on the chemistry the inserted battery has,
regardless of its size or capacity. All twelve channels are independent, so every channel can be
occupied by different batteries, that are distinguished as follows:
Type 1: NiMH, NiCd:
Please insert your batteries in your IQ312. The charger can be powered before or after
inserting the batteries, it makes no difference for the functionality. After the charger
recognizes the NiMH or NiCd cells, the charging process starts automatically. The current
gets set to 500mA for each slot.
Type of battery Charging current per slot
- mA
NiMH, NiCd 500

After the charger has accepted the battery, the display lights up for 30s and signalizes
hereby that the battery is alright and ready to charge. Also a charge-current-arrow of the
according channel on the display shows that the battery is already charging.
Also visible on the display, there are bars that show the actual state of charge of each
channel.
Type 2: Li-Ion:
Charging Li-Ion batteries works the same as charging NiMH or NiCd batteries. You can
insert your batteries before or after powering the charger. That makes no difference in
functionality. Now there are two options how to choose the charging current for each
battery. It depends on which slots are used.
Every two adjacent slots (e.g. slot 1 and 2; slot 3 and 4; slot 5 and 6 and so on) are paired
and share their power. If only one of two paired slots (e.g. slot 5 is empty and slot 6 is
charging) are occupied by a Li-Ion battery, then the charging current is set to 1000mA.
Otherwise if both paired slots are occupied, the charging current gets shared and every
slot is sourced with 500mA.

two paired slots is occupied
