Ultra-flat lithium coin batteries CR2016 (3V, 80mAh) provide an extremely thin 1.6 mm design, combining "Anti-Leak" protection and precise 3V voltage for wristwatches and electronic smart cards.
At only 1.6 mm thick, the CR2016 (IEC 5000LC) is the thinnest element in the 20.0 mm diameter group, making it an integral component for equipment with extremely thin motherboards or watch architectures. The "Lithium Cell" series from VIDEX encapsulates 80mAh of clean energy in this small volume, which maintains a slow discharge rhythm (Continuous discharge) and prevents power fluctuations under stress conditions. The built-in steel housing, together with an innovative polymer sealing ring (Anti-Leak technology), 100% blocks dangerous chemical fumes, keeping the inside of the equipment free from oxidation risks throughout the 5-year guaranteed storage period. Furthermore, the composition uses completely no cadmium and mercury.
CR2016 Flat Lithium Profile Specification:
- Ultra-Thin (1.6 mm) Format: Designed for exclusive electronic cards, smart bowls, and watches where every millimeter matters.
- Reliable 80mAh Capacity: Will provide long-lasting and reliable operation in low-consumption equipment without interruptions in timekeeping.
- Excellent Anti-Leak Hermeticity: Careful construction prevents leaks onto expensive circuit boards in both daily vibrations and temperature (20±2°C) extremes.
Choosing an element of the correct thickness helps avoid bending and breaking the equipment's contacts, extending its service life. In cases where the physical socket requires a smaller (16.0 mm) diameter but allows for a greater thickness (3.2 mm) for extra power (130mAh), an excellent choice will be our CR1632 batteries.
Q: What are the IEC parameters of the CR2016 battery and its unique form factor advantage?
Q: Why are two CR2016 batteries often connected in series in laser pointers or mini flashlights?
Q: How does a lithium CR2016 behave during prolonged daily wear on the wrist (e.g., in thin watches)?
Q: Is it safe to carry a loose CR2016 spare battery in a pocket along with metal keys?
Q: Can a CR2016 battery technically be placed in a single CR2032 socket by filling the empty space with folded foil?
A: The CR2016 is 20.0 mm in diameter, but its thickness reaches only 1.6 mm, providing 90 mAh capacity. This is the thinnest of the standard 20.0 mm series elements, specifically designed for ultra-thin door access chip cards (RFID/NFC) and flat quartz wristwatches.
Q: Why are two CR2016 batteries often connected in series in laser pointers or mini flashlights?
A: By stacking two 1.6 mm thin CR2016 elements one on top of the other, a 3.2 mm thickness with a doubled 6.0V (3V+3V) voltage is created in the device's socket. This solution provides a higher initial voltage for starting regular LED light diodes or laser amplifiers, unlike a single CR2032 (3V), even though the thickness of both options (3.2 mm) is identical.
Q: How does a lithium CR2016 behave during prolonged daily wear on the wrist (e.g., in thin watches)?
A: The thin profile (1.6 mm) means a smaller volume of chemical reactants (90 mAh), so it will power large watch mechanisms for a significantly shorter time. However, the low self-discharge of the VIDEX CR2016 lithium element makes it perfectly suited for ultra-thin stepper motors, ensuring years of chronometer operation even with low capacity.
Q: Is it safe to carry a loose CR2016 spare battery in a pocket along with metal keys?
A: A loose coin cell battery, whose wide (+) and (-) poles come into contact with metal objects (keys, coins), will cause an instantaneous short circuit. As a result, the 3.0V lithium element will massively overheat in a few minutes and may even deform the outer steel shell, therefore spares must always be kept in insulated packaging.
Q: Can a CR2016 battery technically be placed in a single CR2032 socket by filling the empty space with folded foil?
A: Such DIY methods are extremely dangerous in microelectronics because the foil, although filling the 1.6 mm gap, creates high contact resistance and heating under load. Furthermore, it does not guarantee a stable electrical circuit, which in smart devices (e.g., bank authentication calculators) can cause data corruption or memory loss.
