Maxell Coin Type Lithium Manganese Dioxide Battery (CR)
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, both for powering devices such as wristwatches and electronic calculators and can be used in all types of electronic devices mainly as memory and RTC backup.
The CR1025 is a high quality 3V Lithium coin cell from Maxell. It is 10mm in diameter and 2.5mm thick.
Features & Benefits
Optimum for Memory and RTC Backup
Displays long-term stable operating voltage at low load discharge.
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 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 seal of the seal structure and application of sealant keep self-discharge to about 1% per year.
