Q1: What is the capacity of the Vapcell H16?
A: It has a nominal capacity of 1600mAh (0.2C discharge) and a rated capacity of 1550mAh, making it one of the highest-capacity cells in the 18350 format.
Q2: What is the maximum discharge current?
A: The maximum continuous discharge current is 5A at 25°C ambient temperature, suitable for medium-power load devices.
Q3: What is the difference between flat top and button top? Which should I choose?
A: Flat top batteries have a flat positive terminal, while button top batteries have a raised contact point. Choose based on your device’s battery compartment design—most modern compact flashlights use flat top cells, while some devices require button top for proper contact.
Q4: Does this battery have a protection circuit?
A: No. The H16 is an unprotected bare cell. Ensure your device has over-discharge protection, or use a charger with over-discharge protection, to avoid discharging below 2.5V.
Q5: Can I charge it with a standard Li-ion charger?
A: Yes. Use a charger that supports 18350 Li-ion batteries. Standard charging current is 320mA, with a maximum of 1120mA.
Q6: How should I store the 10-pack?
A: Store in a cool, dry place (-20°C to +25°C for long-term storage), keep at approximately 50% charge (around 3.6V), and use insulating protective cases to prevent short circuits.
