INR18650-35E 3500mAh 3.7V Lithium Battery Cell 18.5 x 65.2mm

This INR18650-35E rechargeable lithium battery is a single 18650-size cell with a standard capacity of 3500mAh and a rated voltage of 3.7V. It is intended for compatible devices and DIY builds that use the 18650 format, including torches, power banks, and other equipment accepting a cell of this size. The cell has an internal resistance below 30mΩ, which supports stable current delivery in regular electronic applications. Its charging method is DC 4.2V constant voltage, and the maximum charge current is 1C, or 3500mA. The battery measures 18.5mm in diameter and 65.2mm in height, so it fits standard 18650 compartments where these dimensions are specified. The nominal voltage is also listed as 3.6V in some references, while the rated voltage is given as 3.7V. No charger, case, or other accessories are included. No cycle life, temperature range, certification, or manufacturer warranty details are provided, so buyers should rely only on the stated specifications.

Features and Construction

The core specifications of this cell are its INR18650-35E format, 3500mAh standard capacity, 3.7V rated voltage, and low internal resistance. These details help determine whether the battery suits a particular device or project. The source text gives clear charging parameters and physical dimensions, but it does not describe the internal electrode materials or separator construction.

Material and Build

The battery is a lithium rechargeable cell in INR18650-35E format. Its lithium-based chemistry supports repeated recharge cycles, with a rated voltage of 3.7V and a standard capacity of 3500mAh. The internal resistance is below 30mΩ. No further material composition or build details are stated in the source text, so no additional claims can be made about the electrodes, casing, or internal structure.

Size and Practical Fit

The cell measures 18.5mm in diameter and 65.2mm in height. This matches the standard 18650 size envelope, which is commonly used in devices with cylindrical battery compartments. The 3500mAh capacity and 3.7V rated voltage apply when the cell is used within its stated charging and discharging parameters. Buyers should confirm that their device or project accepts a single 18650 cell with these exact dimensions before ordering.

Uses and Placement

This INR18650-35E cell can be used in compatible torches, power banks, and DIY electronics that require an 18650-size battery. It is also suitable as a replacement cell in equipment designed around the 18.5mm x 65.2mm form factor. The stated 3500mAh capacity and 3.7V rated voltage provide a baseline for estimating runtime in low-to-moderate drain devices, though actual performance depends on the host device.

Event or Professional Use

For professional or event-related equipment, such as portable lighting or backup power for small devices, this cell offers a standard 18650 format with a 3500mAh capacity. The DC 4.2V constant voltage charging method and 1C maximum charge current allow compatible chargers to be used within the stated limits. No professional certifications or industrial ratings are provided, so it should only be used in devices that do not require such approvals.

Everyday Home Use

Around the home, this battery can serve in torches, handheld fans, and other everyday gadgets that take a single 18650 cell. Its 3500mAh capacity and 3.7V rated voltage are suitable for regular low-drain applications. The internal resistance below 30mΩ helps maintain stable output during use. As no charger is included, a compatible DC 4.2V constant voltage charger is required to recharge the cell.

Benefits and Buying Value

The main practical value of this INR18650-35E cell lies in its stated 3500mAh capacity, 3.7V rated voltage, and standard 18650 dimensions. These features make it a direct replacement option for compatible devices and a useful component for DIY builds. The cell can be recharged repeatedly using the specified DC 4.2V constant voltage method, provided the charger does not exceed the 1C maximum charge current.

Reuse and Low Maintenance

As a rechargeable lithium cell, this battery can be used multiple times instead of a single-use alternative. Its 3500mAh capacity and 3.7V rated voltage are intended for regular cycling within compatible equipment. The source text does not state a cycle life figure, so no lifespan claim can be made. Maintenance is limited to charging with a suitable DC 4.2V constant voltage charger and observing the 1C maximum charge current. No other care instructions are provided.

Why Choose This Product

This cell is a straightforward option for buyers who need a single INR18650-35E battery with a 3500mAh capacity and 3.7V rated voltage. Its 18.5mm x 65.2mm dimensions match the common 18650 size, and the internal resistance below 30mΩ is a useful specification for stable current delivery. The package includes one battery only, with no charger or accessories. Buyers should compare the stated voltage, capacity, and size against their device requirements before purchase, as no additional performance data or compatibility guarantees are supplied.
