3. Operating Instructions
This section details how to properly charge your rechargeable batteries using the BC-904S charger.
3.1. Inserting Batteries
The charger supports AA, AAA, and 9V NiMH/NiCd batteries. Always ensure you are using rechargeable batteries of the correct type and size.
- For AA/AAA Batteries: Insert up to four AA or AAA batteries into their respective slots, observing the correct polarity (+/-) indicated inside the charger. The charger has two independent charging channels for AA/AAA batteries, allowing you to charge 2 or 4 batteries.
- For 9V Batteries: Insert up to two 9V batteries into the dedicated 9V slots, ensuring correct polarity.

3.2. Charging Process
Once batteries are correctly inserted and the charger is plugged into a power outlet, the charging process begins automatically.
- LED Indicators: Red LED indicators will illuminate to show that charging is in progress for the respective battery slots.
