VOLTAGE DEFINITIONS OF LITHIUM ION BATTERY 18650
Open Circuit Voltage (OCV):
Equilibrium potential 3.0 V to 4.2 V on average, dependent on temperature, storage duration and state of charge.
Nominal Voltage is typically 3.7 V, see specifications for individual batteries.
End of Discharge Voltage:
The voltage at the end of discharging is 2.75 V to 3.2 V per cell, depending on discharge rate and temperature.
End of Charge Voltage: Terminal voltage after charge is 4.2 V.
CAPACITY DEFINITIONS OF LITHIUM ION BATTERY 18650
The capacity C of the lithium ion battery is defined by the discharge current I and the discharge time t: C = I * t
I = constant discharge current
t = duration from the start of discharge to end of the discharge
Rated capacity: The rated capacity C represents the energy delivered by the battery at a discharge rate of 5 h (0.2 CA) expressed in mAh (milliampere-hours). The reference temperature is + 22 °C ± 3 °C, and the final discharge voltage is 3.0 V.
The factors that affect the available capacity are:
- Discharge rate
- End of discharge voltage
- Ambient temperature
- State of charge
- Cycle history
At the higher than nominal discharge rates, the available capacity is accordingly reduced.
CURRENT DEFINITIONS OF LITHIUM ION BATTERY 18650
Charge and discharge rates of Cylindrical lithium ion battery may be given as multiples of the Rated Capacity (C) in Ampères (A) with the term CA.
Rated Capacity C = 1000 mAh
0.1 CA = 100 mA, 1 CA = 1000 mA
Nominal Discharge Current:
The nominal discharge current of a CellPac LITE battery is the 5 hour discharge current (0.2 CA). It is the current at which the nominal capacity of a cell is discharged in 5 hours.
I = C/t = C/5 = 0.2 CA when t = 5 h
The below 18650 lithium-ion battery and lithium-ion battery pack size include the protection circuit module. Samples available, short lead time, and fast global shipping.

2023 New In Rechargeable Lithium Ion Battery List
A hard case lithium-ion battery is a type of lithium-ion battery that is designed with a durable outer casing to protect the battery cells inside. These batteries are commonly used in applications where the battery may be subject to impact, vibration, or other types of mechanical stress, such as in power tools, remote-controlled vehicles, and marine applications.
The hard case of a lithium-ion battery is typically made of materials such as plastic, metal, or composite materials that are designed to withstand impacts and protect the battery cells from damage. The internal cells of a hard case lithium-ion battery are the same as those used in other lithium-ion batteries, consisting of a positive electrode made of lithium cobalt oxide, a negative electrode made of graphite, and a lithium-ion electrolyte.
One advantage of hard case lithium-ion batteries is that they can provide additional protection against damage and extend the overall lifespan of the battery. They are also less prone to leakage or rupture than soft-shell lithium-ion batteries, which can be an important consideration in some applications.
