Maxell Corporation of America, Inc. Coin Type Lithium Manganese Dioxide Battery CR Series

Overview

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.

Features

• Optimum for Memory and RTC Backup (Fig.1)
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 (Fig.2)
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 (Fig.3)

Applications

●OA Machines (Fax, Copiers, Printers) ●Notebook PCs ●Desktop PCs
●PDAs ●Electronic Dictionaries ●Calculators
●Camcorders ●Digital Still Cameras ●Film Cameras
●Portable CD/MD Players ●Watches ●Medical Instruments, Cash Registers
●Electronic Meters (Gas, Water, Electricity) ●Keyless Entry Systems
●Portable Game Devices ●Remote Controllers
●FA Instruments (Measuring Instruments, Onboard Microcomputers, Sensors)

Overview

Maxell's original sealing technology and highly heat-resistant material expands operating temperature range remarkably, making the batteries supremely suitable for automobile applications — for powering TPMS (Tire Pressure Monitoring System) sensors, for example.

Features

• Wide operating temperature range: -40 deg. C to +125 deg. C
CR2450HR-Ex batteries can even be used at temperatures up to 150 deg. C, depending on other conditions^*.
• Superior leak-resistant characteristics even under high temperature and acceleration.
• Can be used even under 2000G, which is equivalent to driving at 300km/h.
• Electric characteristics are maintained after long periods of exposure to high temperature and humidity.

*When using at temperatures exceeding 85 deg. C, please consult Maxell in advance for conditions of use.
