FAQ:
Q: Is this battery compatible with my 14500 flashlight?
A: Probably NOT. The 16500 has a 16mm diameter, while the 14500 is only 14mm. It will be too thick to fit into a standard 14500 flashlight slot.
Q: Is this battery compatible with my 16340 device?
A: Probably NOT. The 16500 is 50mm tall, while the 16340 is only 34mm tall. The 16500 will be too long.
Q: Is this battery protected (with a built-in PCB)?
A: This is an unprotected bare cell. Please ensure your device has its own built-in protection circuit. We recommend using a dedicated 3.7V/4.2V Li-ion charger.
Q: What is the max discharge current of this battery?
A: This is a standard discharge battery (typically around 1C to 2A), specifically engineered to provide stable, long-lasting current for medium-to-low power devices like wireless microphones and headsets.
Q: How long does it take to fully charge this battery?
A: With a standard 600mA charger, it usually takes about 2.5 to 3 hours to fully charge a 1200mAh battery.
Q: Does it have a built-in USB charging port?
A: No, this is a standard bare battery without a USB port. You will need to use an external smart battery charger.
