Description

Maxell CR Series Coin Type Lithium Manganese Dioxide Battery The coin-type lithium manganese dioxide battery (CR battery) is a small, lightweight battery with an operating voltage of 3V 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. The coin-type lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material, lithium (Li) as its negative active material and an organic electrolyte.

Maxell CR Series Coin Type Lithium Manganese Dioxide Battery

This battery contains lithium, organic solvents, and other combustible materials. For this reason, improper handling of the battery could lead to distortion, leakage*, overheating, explosion, or fire, causing bodily injury or equipment trouble. Please observe the following instructions to prevent accidents.

Battery Reactions
Positive reaction :	MnO2+Li++e- ? MnOOLi
Negative reaction :	Li ? Li++e-
Total reaction :	MnO2+Li ? MnOOLi

Features

Optimum for Memory and RTC Backup
Long-term stable operating voltage at low load discharge.
High energy density(3V)
At 3 volts (nominal voltage), it has about twice the voltage of alkaline button batteries and silver oxide batteries.
Stable discharge characteristics through low internal resistance and high operating voltage
Employs highly conductive electrolyte, lowering internal resistance and providing stable operating voltage. This allows stable power to be obtained, with little change in operating voltage at room temperature as well as high and low temperatures.
Superior leakage resistance and excellent storage characteristics
Employs a leak-resistant organic electrolyte, giving it better leakage resistance than battery types using alkaline electrolytes. Furthermore, the high degree of the seal structure and sealant keep self-discharge about 1% per year.
Superior high rate discarge characteristics

Applications

IoT sensors
Communication tags, Beacons
Wearable devices
Medical thermometers, Activity trackers
CGM (Continuous Glucose Monitoring)
DDS (Drug Delivery Systems)
Keyless entry systems
FA instruments (Measuring instruments, Onboard microcomputers, Sensors)
