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 device
Coin-type lithium manganese dioxide battery “CR”
- Stable operating voltage under long-term low load discharge for Memory and RTC backup
High 3 volt energy density
High energy density. 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 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 seal of the seal structure and application of sealant keep self-discharge to about 1% per year.
Superior high rate discarge characteristics
