Product Features

Compatible with Multiple Battery Sizes

This charger supports AA, AAA, C, D, and 9V Ni-MH/Ni-Cd rechargeable batteries. It allows you to charge up to four AA/AAA/C/D batteries and up to two 9V batteries at the same time, making it perfect for households or workplaces with a variety of battery-powered devices.

Independent Charging Channels

Each battery slot operates independently, allowing you to charge batteries of different sizes and charge levels at once. This feature maximizes convenience and minimizes downtime.

Advanced Charging Technology

Equipped with MCU-controlled –ΔV (minus delta V) detection, the charger automatically stops charging once the batteries are fully charged. It then switches to a trickle charge mode, which helps prolong battery life and prevents overcharging.

Built-In Safety Protections

Safety features include over-voltage, over-current, overheat, and short-circuit protection. The charger also detects defective or non-rechargeable batteries and stops the charging process, preventing damage to both the charger and your batteries.

Dual Power Input Support

The charger supports both AC and DC input (AC cable included), with a wide voltage range of 100–240V AC, 50/60Hz. This makes it suitable for global use and compatible with most power outlets.
