FAQ
Can USB AA rechargeable batteries be charged in any charger?
No! It's not recommended. Our USB AA rechargeable batteries are lithium-ion batteries with a nominal voltage of around 3.7V. They are equipped with an internal PCB board at the positive terminal to regulate voltage. This means they require a specific charging voltage and current. Using a charger not designed for lithium-ion batteries can lead to overcharging, overheating, or other safety hazards.
Our USB AA rechargeable batteries come with a Micro USB cable for charging. It's important to use this cable with a compatible DC 5V/2A USB wall charger to ensure safe and efficient charging. This charger provides the correct voltage and current levels needed for optimal charging without risking damage to the batteries.
