Li-MnO2 Battery

Showing 1–8 of 10 results

Flow meters use lithium manganese dioxide (Li-MnO2) and lithium thionyl chloride (LiSOCl2) batteries as energy sources. LiSOCl2 batteries are popular in flow meters because they provide better energy density and a more efficient cost-per-wattage ratio than Li-MnO2 batteries. However, LiSOCI2 batteries have a poor impulse response, which can lead to a large drop in voltage during transient current loading. Li-MNO2 batteries can deliver moderate pulses.

Li-MnO2 comes in different shapes but the most common are button cells and cylindrical batteries.

The cylindrical lithium manganese oxide battery features several advantages that makes it ideal for use as a power source in industrial applications such as IoT devices and smart meters. It has long-term reliability, having a life span of 10 years.

The coin type lithium manganese dioxide battery (CR battery) is a small, lightweight battery with an operating voltage of 3 V and the ability to operate over a wide temperature range. It has a wide range of applications for powering devices such as various IoT sensors, medical equipment, data loggers and wearable devices.
