Frequently Asked Questions (FAQ):
Q1: What is the advantage of the 18500 size?
A1: The 18500 (18mm diameter x 50mm height) is a compact, high-density power cell. It offers a great balance of size and capacity, making it ideal for devices that require more power than a 14500 but cannot accommodate the length of an 18650.
Q2: Can I use this battery in a device that requires a 18650 battery?
A2: No, it cannot. While the diameter is the same (18mm), the 18500 is shorter (50mm) than the 18650 (65mm). It will not make proper contact in an 18650 battery compartment. It is only compatible with devices specifically designed for 18500 batteries.
Q3: How many times can I recharge this battery?
A3: LiFePO4 batteries are renowned for their longevity. This battery supports over 2000 full recharge cycles (retaining 80% capacity after 2000 cycles), providing exceptional long-term value.
Q4: What kind of charger should I use for this battery?
A4: You must use a charger specifically designed for 3.2V LiFePO4 batteries with a 3.65V cut-off voltage. Do not use a standard 3.7V/4.2V Li-ion charger or a standard AA/AAA Ni-MH charger.
Q5: Does this battery have built-in protection?
A5: Yes. It has built-in protection against overcharging, over-discharging, and over-current. This ensures the battery automatically shuts off in case of an abnormal condition, preventing damage to the battery itself and the connected device.
