Lithium Ion Battery, 18650 Cell (3.7V 3400mAh, positive cap)

This high-capacity 18650 Lithium-Ion Cell is designed for reliable, rechargeable power. Equipped with an onboard PCM (Protection Circuit Module), this cell offers basic overcharge and discharge protection (we still recommend external protection like a fuse).

With a nominal voltage of 3.7V and a capacity of 3400mAh, this battery is perfect for applications requiring a robust and easy-to-replace power source. It supports a continuous discharge current of up to 5A, making it ideal for moderate to high-drain devices. The charging current is rated at 0.2C, ensuring the batteries' long life.

A cap has been placed on the positive end (it is also marked on the case), altering the dimensions of the 18650 to 69mm x 19mm.

These 18650 cells are widely used in flashlights, DIY electronics, and battery pack assemblies, providing a balance of power and longevity. When operated within recommended limits, you can expect approximately 500 charge cycles over the lifespan of the cell.

Note: For transport, batteries are locked into storage mode, which stops any unwanted discharges during storage or shipping. This will disable all electrical output from the batteries until they have been charged for the first.
