Characteristics

1. Standard Charge

This “Standard Charge” means charging the cell with charge current 1475mA and constant voltage 4.35V at 25℃  for 3hours.

2. Standard Discharge Capacity

The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 590mA with 2.75V cut-off at 25℃  within 1hour after the standard charge.

Standard Discharge Capacity    ≥   2850mAh

3. Initial internal impedance

Initial internal impedance measured at AC 1kHz after rated charge.
Initial internal impedance    ≤   100mΩ

4. Temperature Dependence of Discharge Capacity

Capacity comparison at each temperature, measured with discharge constant current 590mA and 2.75V cut-off after the standard charge is as follows.

General Description:

Cell (lithium-ion rechargeable cell), There shall be no such defects as scratch, rust, discoloration, leakage which may adversely affect commercial value of the cell.

Lithium-ion rechargeable cells, commonly known as lithium-ion batteries, are a type of rechargeable battery widely used in portable electronic devices, electric vehicles, and many other applications.

1. Composition: Lithium-ion batteries are typically made up of one or more cells, each containing a positive electrode (cathode), a negative electrode (anode), and an electrolyte. The electrodes are usually made of materials like lithium cobalt oxide, lithium iron phosphate, or lithium manganese oxide.

2. Rechargeable: Lithium-ion batteries can be recharged multiple times by applying an external electrical current. This makes them a convenient and cost-effective choice for devices that require frequent charging.

3. Energy density: Lithium-ion batteries have a high energy density, meaning they can store a significant amount of energy in a relatively small and lightweight package. This makes them popular for portable electronic devices like smartphones, laptops, and tablets.

4. Cycle life: Lithium-ion batteries have a long cycle life, which refers to the number of charge and discharge cycles they can undergo before their capacity significantly degrades. A typical lithium-ion battery can endure several hundred charge cycles before experiencing noticeable degradation.

Features:

1. Nominal Capacity 2600mAh (0.2C, 2.75V discharge)
2. Minimum Capacity 2550mAh (0.2C, 2.75V discharge)
3. Charging Voltage : 4.2
4 Nominal Voltage : 3.7V

Nominal Specifications:

Others

1. Storage for a long time

If the cell is kept for a long time(3months or more), It is strongly recommended that the cell is preserved at dry and low-temperature.

2. Other

Any matters that specifications does not have, should be conferred with between the both parties.
