Certified primary lithium CR coin batteries with a stable 3V voltage and a 5-year shelf life ensure long-lasting operation of microelectronics.
Compact household devices, medical micro-sensors, and car remotes critically require stable voltage within an extremely limited casing volume. VIDEX CR series lithium coin batteries utilize advanced lithium-manganese dioxide (Li/MnO2) electrochemistry to achieve a 3V operating voltage, doubling the output of standard alkaline elements. This engineering approach provides dense and persistent current output even in equipment that continuously transmits wireless signals. The manufacturing process completely eliminates the presence of heavy metals (mercury and cadmium), reducing environmental impact. The thoughtful Anti-Leak technology and hermetic metal shell prevent any emission of moisture and electrolyte, safeguarding expensive hardware from contact surface corrosion. Due to a low self-discharge coefficient, all cells in this series maintain a fixed 5-year shelf life. This allows technical services and users to safely accumulate battery reserves without the risk of capacity degradation. By installing these power sources, equipment will function stably in extreme temperatures (from -20°C to +60°C), making them suitable for both outdoor and indoor use.
Electrochemical parameters and efficiency:
- 3V lithium voltage: A wide-range discharge curve maintains a stable and constant flow of electricity without sudden drops.
- Anti-Leak design: The steel casing seal eliminates contact between acid or electrolyte and fragile electronics components.
- 5-year shelf life: An optimized chemical formula slows down the natural aging of the battery, preserving initial capacity during standby.
Using original CR series lithium batteries reduces unplanned equipment maintenance and improves long-term device endurance. To expand room automation and ensure long-lasting power for wireless sensors, explore our equipment in the smart home category.
Q: What is the technical difference between CR lithium batteries and standard alkaline (LR) coin cells?
Q: How do storage conditions affect the actual service life of CR lithium batteries?
Q: Why are CR series lithium elements specifically used in outdoor meteorological sensors in winter?
Q: How to interpret the numbers included in the CR series marking, such as CR2032 or CR1220?
Q: Why is it strictly forbidden to attempt to recharge a discharged CR lithium (Primary Lithium) battery?
A: The CR series batteries use lithium manganese dioxide (Li-MnO2) electrochemistry, which provides a fixed 3.0V nominal voltage. Standard alkaline (LR) or silver oxide (SR) elements only provide 1.5V. This 3.0V architecture allows replacing two series-connected coin batteries with a single compact CR element in computer motherboards and car fobs.
Q: How do storage conditions affect the actual service life of CR lithium batteries?
A: The dry Li-MnO2 electrochemical system guarantees a 5-year shelf life with a minimal <2% annual self-discharge. Unlike water-based alkaline electrolytes, lithium cells do not suffer from galvanic corrosion in indoor conditions (15-25°C). The VIDEX CR series retains at least 90% of its initial capacity even after a full 5-year storage cycle.
Q: Why are CR series lithium elements specifically used in outdoor meteorological sensors in winter?
A: CR lithium cells do not contain water electrolyte that could freeze, so their internal resistance remains low even in extreme sub-zero conditions. This technology ensures stable voltage output and data transmission in a temperature range from -30°C to +60°C, which is critically important in the outdoor conditions of the Baltic climate.
Q: How to interpret the numbers included in the CR series marking, such as CR2032 or CR1220?
A: The IEC standard marking precisely indicates the battery's physical geometry in millimeters and tenths of a millimeter. The first two digits indicate the diameter (e.g., 20 = 20.0 mm), while the last two indicate the thickness (e.g., 32 = 3.2 mm, 20 = 2.0 mm). Inserting an element of the wrong thickness can irreversibly deform the micro-device's contact springs.
Q: Why is it strictly forbidden to attempt to recharge a discharged CR lithium (Primary Lithium) battery?
A: CR batteries (Primary Lithium) are non-reversible single-use cells without charging chemistry. Attempting to supply them with reverse charging current releases lithium gases and rapidly raises the internal pressure, which inevitably causes a casing rupture or thermal explosion followed by ignition.
