Frequently Asked Questions

Q: What types of rechargeable batteries are compatible with this 4-slot battery charger?

A: This charger is specifically designed for 1.2V AA and AAA Ni-MH and Ni-Cd rechargeable batteries. It can charge 2 or 4 batteries at a time. Please note it is not suitable for 1.5V batteries or any other battery chemistry such as lithium-ion.

Q: How does the smart IC charging system work?

A: The built-in IC controller monitors each battery during the charging process. It begins with rapid charging to quickly restore capacity, then automatically switches to a gentle trickle charge as the battery reaches full capacity. This two-stage approach ensures batteries are fully charged while protecting them from the effects of overcharging.

Q: How do I know when my batteries are charging?

A: The LED indicator lights up to show that charging is in progress. When the charger is first connected to power, the display activates briefly for about 2 seconds. Please note that the LED will remain on even after your batteries are fully charged, so refer to the estimated charging time formula: Charging Time (hrs) = Battery Capacity × 1.2 ÷ Charging Current (mA).

Q: What cable do I need to power this charger?

A: The charger accepts a DC 5V/2A input via Micro USB or USB Type-C connection. A Micro USB cable is included in the package. You can power it from any standard USB wall adapter, power bank, or USB port that supplies 5V/2A.
