charging for Ni-MH/Cd AA/AAA & 6F22 9V Batteries
Dlyfull's compact 4-slot multi-type charger features pulse charging technology, series charging design, and auto cut-off. With LED status indication and multiple protections, it delivers safe and efficient charging for both AA/AAA and 9V batteries:
1. 4-slot USB charger for Ni-MH/Cd 1.2V AA/AAA and Ni-MH/Cd 9.0V 6F22 rechargeable batteries
2. Series charging design – 4 slots divided into 2 groups (Slot 1&2 for AA/AAA, Slot 3&4 for AA/AAA, with 2 dedicated slots for 9V batteries)
3. AA/AAA batteries must be charged in pairs (same brand and model) – each group charges 2 batteries simultaneously
4. 9V batteries can be charged independently in their dedicated slots
5. Supports any combination of AA/AAA and 9V batteries charging simultaneously
6. Pulse charging technology with multi-parameter detection – safe and efficient charging
7. Multiple charge termination detections: -dV, 0dV, maximum voltage, and maximum time protection (12H)
8. Non-rechargeable battery detection – pre-charge detection with fast flashing alarm
9. White LED indicators – flashing (charging), steady on (fully charged), fast flashing (alarm: bad battery or non-rechargeable battery)
10. Comprehensive protections: overcharge protection, short-circuit protection, reverse-polarity protection (won't damage charger), bad battery identification, and input detection
11. Type-C input for stable and convenient connection
12. Compact and lightweight design: 75×68×25mm, 58g
