Classic lithium CR2032 batteries with 220mAh capacity and a 5-year shelf life ensure continuous operation of computers and household electronics.
The frequently encountered power element standard in computer components and daily small equipment is exactly the 20 mm diameter format. VIDEX CR2032 (5004LC) 3V lithium coin batteries have become the cornerstone in countless systems – from motherboards and car keys to kitchen scales. With a high 220mAh capacity and low self-discharge (under 1% per year), they offer long-lasting voltage retention. The Anti-Leak technology built into the steel casing doubly blocks chemical leakage risks, protecting electronics from destruction. The elements are free of mercury and cadmium. With a fixed 5-year shelf life, users and service technicians can feel secure about the readiness of reserve battery stocks. The battery is capable of promptly delivering current in extreme working environments, which makes it universally applicable in any home or industrial facility.
Universal application parameters:
- 220mAh capacity: A widely used industry standard that serves the vast majority of modern motherboards and remotes.
- Steel sealing: A hermetic casing safely protects device microchips from leakage and the harmful effects of rust.
- 5-year shelf life: Constant electrochemical stability allows buying cells in larger volumes for daily consumption.
Keeping original CR2032 cells on hand is the most reliable way to avoid daily technology downtime. These miniature cells serve as an energy memory element for hardware that temporarily disconnects from the mains, such as our desk lamps with display and clock.
Q: What are the parameters of the CR2032 and why is it considered the industry standard?
Q: What is the critical role of the CR2032 (CMOS) battery on computer motherboards and servers?
Q: Why should quality-approved CR2032 batteries be regularly used in car Keyless-Go remotes?
Q: Can thinner CR2025 or CR2016 batteries be inserted into a thicker CR2032 socket?
Q: How to properly clean the CR2032 contact areas in kitchen and personal scales after leakage?
A: With a 20.0 mm diameter and 3.2 mm thickness (at around 220 mAh capacity), the CR2032 provides a stable 3.0V voltage. The compromise proportion of its dimensions has made it a universal IT and electronics standard – from kitchen scales to heart rate monitor chest straps.
Q: What is the critical role of the CR2032 (CMOS) battery on computer motherboards and servers?
A: While the computer is disconnected from the power grid, the 3.0V CR2032 element continuously powers the BIOS microchip and the real-time clock (RTC) quartz. This 220 mAh power reserve ensures the maintenance of all hardware configurations, boot passwords, and the system clock, typically guaranteeing 3-5 years of autonomy for the motherboard.
Q: Why should quality-approved CR2032 batteries be regularly used in car Keyless-Go remotes?
A: Keyless-Go and Smart Key systems constantly emit low-frequency ping signals (communicating with the car immobilizer in the background). The VIDEX CR2032 Li-MnO2 element prevents rapid voltage drops under peak load, guaranteeing remote car unlocking without connection jitter.
Q: Can thinner CR2025 or CR2016 batteries be inserted into a thicker CR2032 socket?
A: The diameter will be suitable for both (20.0 mm), but the thickness will differ (3.2 mm versus 2.5 mm or 1.6 mm). Inserting a thinner element will not achieve the necessary top and bottom spring pressure, which will cause a computer BIOS reset at the slightest casing impact or a weak radio signal in remotes.
Q: How to properly clean the CR2032 contact areas in kitchen and personal scales after leakage?
A: Lithium cell electrolyte rarely leaks, but in high humidity (in the kitchen), metal contacts can oxidize. The greenish or white oxide layer must be cleaned with isopropyl alcohol (Isopropanol) or contact cleaner using a cotton swab before inserting a new element, as the oxide acts as an electrical insulator.
