Product Overview

The Samsung 21700 58E (Model: INR21700-58E) is a high-performance cylindrical lithium-ion cell, engineered by Samsung—a global leader in lithium battery technology. With a standard discharge capacity of minimum 5330mAh (@0.2C) and 5170mAh (@1C), nominal voltage of 3.64V, it supports 2C continuous discharge (10.66A) and 3C non-continuous discharge, balancing high capacity and stable power output. Its standard 21700 form factor (max diameter 21.78mm, max height 71mm) and max weight of 74g ensure easy integration, while its wide operating temperature range (-10℃ to 60℃ discharge) and excellent storage characteristics make it ideal for e-mobility, power tools, and large energy storage systems. Compared to traditional 18650 cells, the 21700 form factor reduces battery pack complexity by 30%, lowering production costs while boosting energy density and runtime.
