• Weight Comparison

The weight of a battery is a crucial parameter, especially in portable devices. The Panasonic NCR18650ZY is the heaviest battery, weighing 48.0 grams, while the LG battery INR18650M26 is the lightest, weighing 44.0 grams. The Samsung ICR18650-26J2 is in the middle, weighing 46.0 grams.
While weight may not be a significant factor in some applications, such as stationary devices, it can be a critical consideration in portable devices like smartphones, laptops, and drones, where a lighter battery can help increase the device's overall runtime and make it more comfortable to carry.

• Charge Current/Voltage

The charge current and voltage determine the charging time and how long the battery lasts. The LG INR18650M26 has a standard charge current of 1,250mA, while the Samsung ICR18650-26J2 has a standard charge current of 1,300mA.
The Panasonic battery model NCR18650ZY has a slightly lower standard charge current of 1,750mA. All three batteries have a charging voltage of 4.2V.
A higher charge current means the battery can be charged faster, reducing the charging time. However, a higher charge current can also result in increased heat generation, which can affect battery life and safety. Therefore, the optimal charge current depends on the battery's design and intended application.

• Charging Time

The charging time is an important factor to consider when choosing a battery, especially for devices that require frequent charging.
The LG INR18650M26 has a charging time of 2.5 hours, while the Samsung ICR18650-26J2 has a slightly faster charging time of 3 hours. The Panasonic NCR18650ZY has a charging time of 3 hours.
A shorter charging time can be beneficial in applications where the device is frequently used and needs to be recharged quickly. However, fast charging can also result in increased heat generation and may reduce the battery's overall lifespan.

• Max Charge Current

The maximum charge current determines how quickly the battery can be charged. The LG INR18650M26 has a maximum charge current of 2,500mA, while the Samsung ICR18650-26J2 has the same maximum charge current.
The Panasonic NCR18650ZY has a slightly lower maximum charge current of 1,750mA. The maximum charge current is an important consideration in applications where the battery needs to be charged quickly. However, as mentioned earlier, a higher charge current can also generate more heat, which can affect battery life and safety.

• Max Discharge Current

The maximum discharge current determines the battery's ability to deliver power quickly, making it suitable for high-drain devices.
The LG INR18650M26 has a maximum discharge current of 10A, while the Samsung ICR18650-26J2 has the same maximum discharge current. The Panasonic NCR18650ZY has a lower maximum discharge current of 6.2A.
A higher maximum discharge current means the battery can deliver more power quickly, which is useful in high-drain applications such as power tools and electric vehicles. However, a high discharge rate can also generate more heat and reduce the battery's overall lifespan.

• Internal Resistance

The internal resistance of a battery determines the battery's ability to deliver power efficiently.
The LG INR18650M26 has the lowest internal resistance of 12mΩ, followed by the Samsung ICR18650-26J2 with 13mΩ. The Panasonic NCR18650ZY has the highest internal resistance of 23mΩ.
It is important to note that high internal resistance can cause a battery to overheat, which may lead to reduced performance and even damage. Therefore, it is advisable to select a battery with low internal resistance to ensure that it can deliver power efficiently and safely.

• Discharge-Rate

The discharge rate determines how quickly the battery can deliver power, making it suitable for high-drain devices.
The LG INR18650M26 has a discharge rate of 0.2C, while the Samsung ICR18650-26J2 has a slightly higher discharge rate of 0.26C. The Panasonic NCR18650ZY has a lower discharge rate of 0.16C.
It is essential to select a battery with an appropriate discharge rate for the device's power requirements. High-drain devices such as flashlights, cameras, and power tools require batteries with a high discharge rate to deliver power efficiently. In contrast, low-drain devices such as remote controls and clocks require batteries with a low discharge rate.

• Charge-Rate

The charge rate determines how quickly the battery can be charged, making it suitable for devices that require frequent charging.
The LG INR18650M26 has a charge rate of 0.5C, while the Samsung ICR18650-26J2 has the same charge rate. The Panasonic NCR18650ZY has a slightly higher charge rate of 0.7C.
It is essential to select a battery with an appropriate discharge rate for the device's power requirements. High-drain devices such as flashlights, cameras, and power tools require batteries with a high discharge rate to deliver power efficiently. In contrast, low-drain devices such as remote controls and clocks require batteries with a low discharge rate.

• Continuous Discharge Rating (CDR)

The continuous discharge rating (CDR) is the maximum current that can be drawn from the battery for a prolonged period of time without causing damage.
The LG INR18650M26 has a CDR of 5A, while the Samsung ICR18650-26J2 has a CDR of 10A, which is higher than the LG battery. The Panasonic NCR18650ZY has a CDR of 4.9A, which is slightly lower than the LG battery.
CDR is an essential factor for selecting the battery. High-drain devices require batteries with a high CDR to deliver power efficiently without causing damage. In contrast, low-drain devices require batteries with a low CDR.

Which is the Best Battery Model?

If weight is a crucial factor, the LG INR18650M26 is the lightest battery, weighing only 44.0 grams, making it suitable for portable devices that require minimal weight.
If fast charging is a priority, the Samsung ICR18650-26J2 has a faster charging time of 3 hours compared to the other two batteries. It also has a slightly higher standard charge current and a higher continuous discharge rating, making it suitable for high-drain devices.

Conclusion

Based on the comparison of the key specifications and parameters of the three 18650 lithium battery, it is clear that the Samsung ICR18650-26J2 has the highest continuous discharge rating (CDR) and maximum charge current, making it suitable for high-performance devices that require frequent charging and high power output.

When comparing 18650 batteries, the continuous discharge rating (CDR) is a crucial specification to consider. The CDR is the maximum amount of current that a battery can discharge continuously without causing damage to the battery or reducing its lifespan.

The LG INR18650M26 has a lower CDR and maximum charge current, but it has a lower internal resistance, which means that it can deliver more power without a significant voltage drop. The Panasonic NCR18650ZY has the lowest maximum discharge current and CDR, but it has a slightly higher charge rate and a higher nominal capacity.

Ultimately, the choice of the best 2600mAh battery depends on the specific requirements of the device and the application.
