## Long description

Rechargeable 18650 Li-ion battery CSL Computer LXB30Q 3.7V 3000mAh uses high-energy cylindrical cells compatible with devices that accept standard 18650-format lithium-ion batteries. The cell offers a nominal voltage of 3.7 V and a rated capacity of 3000 mAh, providing a balance of energy density and compact size for portable electronics, lighting, and DIY battery assemblies.
Advantages
This 18650 Li-ion cell features high energy density and a cylindrical form factor that fits common 18650 battery compartments. The rechargeable chemistry allows repeated charge–discharge cycles with stable nominal voltage, and the 3000 mAh capacity extends run time compared with lower-capacity cells. Because the product uses quality Samsung cells, it delivers consistent performance and predictable voltage behavior under typical loads.
Suitable for
Flashlights and portable lighting
Power banks and external battery packs
Vape mods and other handheld electronic devices
DIY battery packs and electronics projects using 18650 cells

How to use
Insert the 18650 cell into devices designed for 18650-format batteries, observing correct polarity. Charge the battery only with chargers designed for single-cell lithium-ion batteries or within battery packs that include appropriate charging and protection circuitry. Do not force cells into compartments that require different lengths or diameters, and ensure contact springs or holders provide secure connections. Follow manufacturer guidance of the host device for charging currents and battery orientation.
Usage recommendations
Use the cell within recommended temperature ranges and avoid short circuits, mechanical damage, deep discharge below the device’s allowed cutoff, and exposure to water. For building battery packs, always include a compatible protection circuit (BMS) and balance/charge management appropriate for lithium-ion chemistry. Replace cells in multi-cell assemblies with matching capacity and age to maintain safe and reliable operation.
