for 1.2V Ni-MH/Cd Batteries
charging for Ni-MH/Ni-Cd AA/AAA Batteries
Featuring independent 4-slot charging, pulse charging technology, dual current options, an intuitive LCD display, and comprehensive safety protections, the UN4 delivers reliable and efficient multi-battery charging performance:
1. 4-slot independent charger for Ni-MH/Ni-Cd 1.2V AA/AAA rechargeable batteries
2. Clear LCD display – shows battery voltage, 4-level capacity indicator, and charging status for each slot at a glance
3. Dual charging current options: Slot 1 & 4 support 1.0A fast charging; Slot 2 & 3 support 0.5A charging – ideal for smaller capacity batteries
4. Pulse charging technology – effectively prevents battery polarization effect for longer battery life
5. Multiple charge termination detections: 0dV/-dV cut-off, maximum voltage, maximum time, and over-temperature protection for safe and complete charging
6. Comprehensive safety protections: overcharge protection, short-circuit protection, reverse-polarity protection, and alkaline battery identification (alerts when non-rechargeable batteries are inserted)
7. Type C input (5V/2A) – easy and convenient to use
8. Recommended slot selection: CH1/CH4 for AA batteries; CH2/CH3 for AA/AAA batteries
