Rechargeable Li‑Ion Battery ANSMANN 18650 3.6 V 3350 mAh with Cable (MPN 2447-0122)

ANSMANN 18650 rechargeable Li‑Ion battery, nominal voltage 3.6 V and capacity 3350 mAh, supplied as a single cell with an attached output cable. The cell follows the common 18650 form factor and delivers high energy density for a variety of portable electronics, flashlights, DIY electronics and custom battery pack applications that require a 3.6 V Li‑Ion cell. The attached cable simplifies connection when replacing a single cell or integrating into existing wiring harnesses.

Advantages

This 18650 Li‑Ion cell offers a relatively high capacity of 3350 mAh in the standard cylindrical 18650 size, providing extended runtime compared with lower‑capacity cells. The pre‑attached cable reduces installation time and avoids the need for additional soldering or holders in many applications. As a rechargeable Li‑Ion chemistry, it delivers consistent voltage under load and good energy density for compact device designs.

Suitable for

• Flashlights and portable lighting devices compatible with 18650 cells
• DIY electronics and hobby projects requiring a 3.6 V rechargeable cell
• Replacement of single cells in battery packs where form factor and voltage match
• Low to medium drain devices and custom assemblies with cable connection

When it may not be suitable

The cell is a single 18650 cylinder with an attached cable and is not a complete multi‑cell battery pack or enclosure. It is not suitable for devices that require protected cells, integrated battery management, or a different nominal voltage such as 3.7 V nominal Li‑ion designs specified by certain manufacturers. Devices that require high continuous discharge current beyond the cell's safe ratings or specific temperature tolerance should be verified before use.

Key specifications

• Cell type: cylindrical 18650 lithium‑ion
• Nominal voltage: 3.6 V
• Rated capacity: 3350 mAh
• Configuration: single cell with attached output cable
• Chemistry: lithium‑ion (Li‑Ion)

How to use

Install the cell by connecting the attached cable to the device’s battery connector or wiring harness observing correct polarity. Ensure the device’s charging circuit or external charger is compatible with Li‑Ion cells and the cell’s nominal voltage. Do not force the cell into holders that compress or deform the cylinder; the 18650 size requires appropriate mechanical support. Charge and discharge the cell following the device manufacturer’s guidance and standard Li‑Ion safety practices.

What to consider before purchase

• Verify that your device accepts a single 18650 cell and the nominal 3.6 V rating
• Confirm required discharge current and ensure the cell’s specifications meet device demands
• Check whether a protected cell or integrated battery management is required for your application
• Ensure the attached cable length and connector type are suitable for your installation

Usage recommendations

Use a charger designed for Li‑Ion chemistry and monitor the cell during initial cycles. Store the battery partially charged in a cool, dry place when not in use, and replace the cell if you observe swelling, excessive heat, or significant capacity loss.
