Top 3 Customer Questions & Concerns 🙋‍♂️

⚙️ Can I charge standard AA or AAA Ni-MH batteries in this?

No, this unit is designed exclusively for 3.7V Lithium-Ion rechargeable batteries. Charging standard 1.2V or 1.5V Ni-MH/Ni-Cd AA/AAA batteries may damage the cells or the charger due to voltage incompatibility.

🔌 How do I know when the batteries are done charging?

The built-in LED indicator light on the body turns red while actively charging and switches to green (or turns off depending on mode) when the batteries reach full charge and power automatically stops.

⚠️ Can I charge just one battery at a time?

Yes. The bays operate independently, allowing you to charge either a single battery or two batteries simultaneously.
