CR1220 batteries provide reliable 3V power to microelectronics.
The CR1220 microbattery format (12.5 mm x 2.0 mm) provides a reliable 40mAh capacity, making them one of the most frequently used 3V cells in extremely compact electronic assemblies. They serve as motherboard CMOS memory backup batteries, blood glucose meter power sources, and smart home microsensor energy bases. The stabilized lithium discharge curve maintains precise operation without exposing the equipment to overvoltages. The insulated metal casing protects devices from electrolyte leaks. The battery shelf life reaches 5 years.
Physical and technical advantages:
- 40mAh power: Maintains smooth operation of sensors and computer memory for years.
- Rigid casing: Protects against physical impacts during assembly.
- Ecological safety: The composition meets all heavy metal restrictions.
The innovative design and power provide maximum confidence in the long-term stability of any professional sensor system. In cases where an extremely small diameter with a minimal profile is needed for precision mechanics, use the compact CR1216 Batteries. Safety standards require the use of only certified and tested elements in the equipment. Properly selected components that meet technical specifications significantly extend the operating cycle of the hardware in extreme working conditions. Careful selection of materials and engineering during the manufacturing process ensure maximum reliability and safety in all technical application scenarios. This analytical approach is fundamental to today's demanding industrial needs, where there is no room for error and where energy efficiency is always a primary requirement for any reliable system. This allows for significant resource savings in the long run, guaranteeing safety.
Q: What are the IEC standard dimensions of the CR1220 battery and its primary application in the IT sector?
Q: Why are CR1220 lithium cells chosen for the internal memory blocks of medical equipment (glucometers)?
Q: What happens in a PDA or laptop when the CR1220 (CMOS) battery is discharged?
Q: Is it permitted to recharge a CR1220 lithium battery if its capacity has depleted?
Q: What is the working temperature range and shelf life guarantee of the CR1220 battery?
A: The physical dimensions of the CR1220 are 12.5 mm in diameter and 2.0 mm in thickness, generating around 35 mAh capacity at 3.0V voltage. This microscopic format is the de-facto standard for powering the BIOS and RTC (real-time clock) memory of ultra-compact laptops, PDAs, and small-sized motherboards.
Q: Why are CR1220 lithium cells chosen for the internal memory blocks of medical equipment (glucometers)?
A: Preserving the user's measurement log (RAM) in a glucometer while it is turned off requires a continuous microampere power supply for months. The VIDEX CR1220 Li-MnO2 dry electrochemistry eliminates the risk of corrosion on circuits and maintains a constant 3.0V background, ensuring data retention for 1-2 years.
Q: What happens in a PDA or laptop when the CR1220 (CMOS) battery is discharged?
A: When the voltage drops below 2.5V, the device's CMOS microchip cannot maintain the memory, which causes the system time (Date/Time) to reset every time the device is turned off, and error messages (CMOS Battery Failure) may appear upon booting.
Q: Is it permitted to recharge a CR1220 lithium battery if its capacity has depleted?
A: Primary Lithium (single-use lithium) series, including the CR1220, contain active metallic lithium, which makes recharging them strictly prohibited. Applying voltage from a charger causes uncontrollable heating, electrolyte boiling, and subsequent explosion of the hermetic casing.
Q: What is the working temperature range and shelf life guarantee of the CR1220 battery?
A: Li-MnO2 lithium elements are resistant to temperature fluctuations from -30°C to +60°C. Ensuring dry storage in room conditions (15-20°C), the element's self-discharge does not exceed 2% per year, so the manufacturer guarantees a minimum 5-year shelf life for spare elements without noticeable power loss.
