CR1220
One of the most reliable 3V Lithium batteries on the market! If your computer memory and remotes require instant and stable power, the VIDEX CR1220 lithium button battery is your safest choice.
Why choose Lithium (CR) batteries:
- Pazīstama arī kā (analogi): DL1220, ECR1220.
- Perfect operation in the cold: Doesn't lose capacity even in freezing temperatures (essential for car remotes in winter).
- Massive longevity: Retains energy on the shelf and in devices for an extremely long time - ideal for background processes.
- Leakage guarantee: Industrially sealed casing that completely eliminates acid leakage.
Don't buy cheap knock-offs, choose real VIDEX lithium power. Buy affordably at open tools!
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.
