Product Overview

The Youxi 18650 is a standard cylindrical lithium-ion cell designed for applications that use the common 18650 battery format.

The name 18650 refers to the approximate physical size of the cell:

• Approximately 18mm in diameter
• Approximately 65mm in length
• Cylindrical construction

With a rated capacity of 1800mAh, the cell stores approximately 6.66Wh of nominal energy.

This is a single battery cell, not a complete battery pack. It does not include a charger, enclosure, or confirmed built-in protection circuit. Depending on the application, it can be used individually or combined with other cells to create a larger battery pack.

Key Benefits

Suitable for Low-Power Applications

The listed 0.5C discharge rate makes this cell better suited to relatively light loads such as LED lighting, solar lanterns, and other small electronic applications.

Widely Used 18650 Format

The 18650 format is commonly used across many battery-powered products. Compatible holders, pack components, and charging solutions are readily available, making replacement and pack assembly more convenient.

Useful Capacity for Compact Devices

At 1800mAh, the cell offers a practical balance between capacity and size for applications where a compact rechargeable power source is required.

Convenient for Bulk Requirements

The supplied information lists 100 cells per carton, which can be useful for workshops, repair businesses, lighting manufacturers, and battery-pack assemblers working with larger quantities.

• Maximum charge current
• Terminal type, such as flat-top or button-top
• Exact cell dimensions
• Protection-circuit status
• Operating temperature range
• Storage temperature
• Continuous and peak discharge limits
• Cycle-life test conditions

Applications

The Youxi 18650 1800mAh cell can be considered for applications such as:

• LED lights
• Emergency lighting
• Solar lanterns
• Solar lights
• Small electronic devices
• Replacement 18650 cells
• Custom low-power battery packs
• Repair and maintenance applications

For any application with a significant current demand, verify the required current against the confirmed discharge rating before selecting this cell.

Battery Replacement & Pack Assembly Guidelines

When replacing or assembling 18650 cells, correct polarity and cell matching are important.

Recommended Practices

• Switch the equipment off before removing or installing a cell.
• Check the original battery's polarity before removing the old cell.
• Confirm that the replacement cell is 3.7V nominal and 18650 format.
• Check whether the device requires a flat-top or button-top terminal.
• Do not mix old and new cells in the same multi-cell pack.
• Avoid mixing cells with different capacities or specifications.
• Keep the cell away from excessive heat.
• Never short-circuit the cell terminals.
• For multi-cell battery packs, use an appropriate BMS where required.
• Match cell voltage before connecting cells together.

Important: Lithium-ion cells can become hazardous if they are short-circuited, overheated, incorrectly charged, physically damaged, or assembled improperly.

Using the Cell for Battery Packs

If multiple Youxi 18650 cells are used together, the pack configuration determines the final voltage and capacity.

Series Connection

Connecting cells in series increases voltage.

For example:

4 × 3.7V = 14.8V nominal

Parallel Connection

Connecting cells in parallel increases capacity.

For example:

2 × 1800mAh = 3600mAh

A 4S2P configuration would therefore contain 8 cells and provide approximately:

• 14.8V nominal
• 3600mAh capacity
• Approximately 53.28Wh nominal energy

The actual pack design must be based on the application, required current, BMS, charger, and confirmed cell specifications.

Frequently Asked Questions

What is the Youxi 18650 1800mAh lithium cell?

It is a rechargeable lithium-ion cell in the 18650 cylindrical format. The cell has a rated capacity of 1800mAh and a nominal voltage of 3.7V.

It is intended for applications such as LED lighting, solar lanterns, small electronics, and suitable replacement battery packs.

What does 18650 mean in a battery cell?

18650 is a cylindrical battery size designation. It generally refers to a cell approximately 18mm in diameter and 65mm long.

Exact dimensions can vary slightly, so check the product specification when physical fit is important.

What are the capacity and voltage of the Youxi 18650 cell?

The listed specifications are:

• Capacity: 1800mAh
• Nominal voltage: 3.7V
• Nominal energy: approximately 6.66Wh

The energy calculation is:

3.7V × 1.8Ah = 6.66Wh

How should I charge a Youxi 18650 1800mAh cell?

Use a charger designed specifically for the applicable 3.7V nominal lithium-ion cell and follow the confirmed charge-voltage and current specifications for the cell.

The supplied information lists a charging time of 2–3 hours, but the recommended charge current and exact charging conditions should be confirmed before publishing them as official specifications.

What is the discharge rate of the Youxi 18650 cell?

The supplied specification lists a 0.5C discharge rate.

For an 1800mAh cell:

1.8Ah × 0.5C = 0.9A

This makes the cell more appropriate for relatively light-load applications.

How many cycles does the Youxi 18650 1800mAh cell provide?

The listed cycle life is 600 cycles.

However, the test conditions were not provided. Actual cycle life can vary depending on charge current, discharge depth, temperature, storage conditions, and usage pattern.

Can I use this cell for LED lights and solar lanterns?

Yes. LED lighting and solar lanterns are among the applications supplied for this product.

Before selecting the cell, compare the device's current requirement with the cell's confirmed discharge capability.

Can I use the Youxi 18650 cell for power tools or e-bikes?

The supplied 0.5C discharge rating makes it unsuitable for many high-current applications unless the pack is specifically designed with enough parallel cells.

For power tools, e-bikes, or other high-load equipment, it is better to select a cell with a discharge rating appropriate for the application's continuous and peak current requirements.

Can this cell be used as a replacement for another 18650?

It can be considered as a replacement when the following requirements match:

• Nominal voltage
• Physical size
• Capacity
• Terminal type
• Current requirement
• Device or pack specifications

Check whether the original cell uses a flat-top or button-top terminal before ordering.

How do I replace an 18650 lithium cell?

Switch the equipment off and identify the positive and negative terminals before removing the old cell.

Install the replacement in the same orientation and make sure it is held securely. For multi-cell battery packs, it is generally better to replace the complete matched set rather than mixing an old cell with a new one.

If the pack requires welding, BMS work, or other battery assembly, use appropriate equipment and trained personnel.

Does the Youxi 18650 cell have a protection circuit?

The supplied information does not confirm whether this particular cell includes a protection circuit.

Unless the product specification explicitly confirms built-in protection, treat it as a bare cell and use appropriate protection in the finished battery pack.
