Difference between 26650 battery and 18650 battery

Chemistry

Most of 26650 battery is a rechargeable LiFePO4 battery. However, Most of 26650 battery is a rechargeable NiCoMn ternary.

Dimension

When it comes to size, the main difference between 26650 battery and 18650 battery is the diameter. 26550 battery is 65 mm in length and 26 mm in diameter, whil 18650 battery is 65 mm in length and 18 mm in diameter.

So due to a larger diameter, the total size and weight of the 26650 battery are bigger.

Capacity

The capacity of the 18650 rechargeable lithium battery is 1200mAh to 3600mAh. However, the 26650 rechargeable lithium batteries come with a large capacity in comparison to the 18650 Battery. the capacity of 26650 rechargeable lithium battery is 2500mAh to 4000mAh.

Voltage

The 18650 rechargeable batteries can take up to 4.2V maximum. Their charge current can be 1C. (What Is Battery C Rating) On the other side, the 26650 batteries are made up of Lithium iron phosphate material and they can achieve a nominal voltage of around 3.2 volt per cell. However, the suggested charging voltage can be up to 3.65 volts.

Discharge rate

The discharge rate refers to the measurement of the maximal power that a battery can deliver at a time. The discharge rate is divided into two types. The maximum discharge rate is max absolute full power in 30s. Continuous rate is the maximal power that can be equipped over long periods. The continuous rate always lower than the maximum discharge rate.

Application

Basically, both batteries are used for vaping devices, flashlights, toys, and torches.

However, according to the different application, the 26650 have more size and capacity than 18650 battery.

Which battery is better? 26650 battey or 18650 battery?

The selection of the best battery type usually depends upon the requirements and needs of an individual. It is important to mention that, 18650 rechargeable batteries are more famous and verified by the market. Also they carry more power and can serve today’s high-tech flashlights.
