What Is a 3.6V Lithium Battery? Full 2025 Guide
A 3.6V lithium battery is a rechargeable or primary (non-rechargeable) lithium cell designed with a nominal voltage of
3.6V lithium batteries include lithium thionyl chloride, Li-ion, and other variants tailored for specific purposes. Popular examples like the 18650, ER26500, and AA variants cover diverse uses. They offer high energy density, making them ideal for compact yet powerful applications.
The 3.6V Li-ion battery is high voltage battery cell, while the 3.2V Li-ion battery has a greater cycle life but a lower voltage. This means that 3.2V batteries are more suitable for applications that require relatively longer periods of power, such as medical devices and renewable energy systems.
3.7V Li-ion: In most devices, a 3.7V battery can replace a 3.6V one because their voltage difference is minimal. 3.2V LiFePO₄: Possible substitute if the device tolerates slightly lower voltage. NiMH (1.2V) packs: Not a suitable replacement unless multiple cells are connected in series.
The high energy in 3.6V lithium batteries helps these devices keep working well, even when the conditions are tough. For IoT devices, these batteries give a steady energy supply, so the devices stay connected and send data with no trouble. Their high energy density and reliable power make them a must-have in many different fields.
