FAQ:
Q: Is this 14650 battery compatible with my device that uses a 14500 battery?
A: No, they are not interchangeable. Both are 14mm in diameter, but the 14650 is 65mm long, while the 14500 is only 50mm long. It will physically not fit in a 14500 compartment.
Q: Does this battery fit into a standard spring-loaded flashlight?
A: No. Because it has metal solder tabs welded to the ends, it will not work in a standard battery spring compartment. It must be soldered directly onto the circuit board.
Q: I see it says 3.6V, but my old battery says 3.7V. Will it work?
A: Yes, perfectly. 3.6V is the nominal voltage of Sanyo/Panasonic cells. It is fully charged to 4.2V, which is exactly the same as standard 3.7V Li-ion batteries. They are 100% cross-compatible.
Q: Is the "500+ cycle life" actually true?
A: Yes. Genuine Sanyo cells have advanced chemistry and very low internal resistance (70mΩ), which significantly reduces degradation, allowing them to easily reach 500+ charge cycles, unlike low-quality generic cells.
