Technical Specifications
Battery Type: 18650 (Cylindrical: 18mm diameter, 65mm height).

Chemistry: Lithium-ion (Li-ion).

Capacity: 1800mAh (milliampere-hours).

Voltage: * Nominal: 3.7V (The average operating voltage).

Full Charge: 4.2V.

Cut-off (Empty): 2.5V – 2.75V.

Performance & Use Cases
At 1800mAh, this is considered a low-to-medium capacity battery. High-end 18650s (like those from Sony, Samsung, or Panasonic) typically range from 2500mAh to 3500mAh.

Best For:

Budget LED Flashlights: Often included as the "stock" battery for zoomable torches.

Portable Fans: Small USB-rechargeable desk or handheld fans.

Solar Garden Lights: Used in larger solar units that require more than a standard AA.

Low-Power DIY Electronics: Powering Arduino projects or small RC toys.

Not Recommended For:

High-Drain Devices: Avoid using these in high-wattage vapes, power tools, or high-lumen tactical flashlights. Generic batteries often lack the "discharge rate" (C-rating) needed for these devices and can overheat.

Important Safety Tips
Because YIN LO JYD is a generic brand, it often lacks a built-in protection circuit (BMS). Please follow these precautions:

Do Not Overcharge: Only use a dedicated Li-ion charger that stops at 4.2V.

Check for Wrappers: If the colored plastic skin is torn or peeling, stop using it immediately. The entire metal body of the battery is the negative terminal; a tear can cause a short circuit.

Storage: Never carry these loose in your pocket with keys or coins. Use a plastic battery case to prevent accidental firing or venting.
