Lithium coin batteries CR1620 (3V, 70mAh) stand out with a reduced 2.0 mm thickness and "Anti-Leak" hermeticity, ensuring stably slow discharge for car immobilizer remotes and micro-sensors.
This (IEC format) 3V lithium element is the 16.0 mm diameter golden mean between the thicker CR1632 and the ultra-thin CR1616. With a 70mAh capacity, the VIDEX-developed battery is perfectly balanced for long-term and non-aggressive power output (Continuous discharge), making it a classic choice for modern car keys and health monitoring microchips. The integrated "Anti-Leak" protection means that the steel housing, together with polymer insulation, protects against oxidative leaks regardless of how long the battery stays in the device. All "Lithium Cell" cells in this series are ecologically safe (0% Mercury), and the manufacturer guarantees them a long 5-year shelf life.
CR1620 Lithium Cell Technical Base:
- Optimized 2.0 mm Profile: The standard thickness chosen by manufacturers for security remotes, without exerting pressure on the motherboard contacts.
- Reliable 70mAh Capacity: Guarantees that devices will receive a stable and linear 3V current in a slow discharge rhythm without voltage drops.
- Anti-Leak Protective Housing: Steel encapsulation that blocks electrolyte migration and the onset of corrosion during sharp thermal fluctuations.
By choosing a power supply of precise thickness, you reduce the chance of breaking the device's fragile battery holders. If the socket is extremely narrow and requires an even thinner format (only 1.6 mm thick) with equivalent capacity (50mAh), the optimal solution is our ultra-flat CR1616 batteries.
Q: What are the IEC parameters of the CR1620 battery and its most common everyday application?
Q: Why is the presence of a lithium CR1620 essential in blood pressure micro-monitors or blood glucose memory models?
Q: How does the working specification of the CR1620 differ from the thinner (1.6 mm) CR1616 model?
Q: How to insert the small 16.0 mm battery into a device without damaging the internal insulation?
Q: How does the cold affect the efficiency of the CR1620 battery if a car key remote is left in the car in winter?
A: The geometry of the CR1620 battery is 16.0 mm in diameter and a reduced 2.0 mm thickness, with a capacity of approximately 75 mAh at 3.0V. It is very common in small electronic car key remotes and delicate wrist blood pressure monitors, where 3.2 mm thick batteries would interfere with closing the housing.
Q: Why is the presence of a lithium CR1620 essential in blood pressure micro-monitors or blood glucose memory models?
A: In medical memory blocks, any prolonged power interruption can mean the loss of the patient's measurement history. Alkaline or silver oxide elements are not optimized for years-long standby mode, whereas the 3.0V CR1620 lithium cell does not emit gases and does not degrade the device's contacts over a 5-year period.
Q: How does the working specification of the CR1620 differ from the thinner (1.6 mm) CR1616 model?
A: Both have the same 16.0 mm diameter and 3.0V base, but the CR1620 (2.0 mm) offers 75 mAh versus the CR1616's 50 mAh. These extra micrometers in thickness allow the VIDEX lithium battery to maintain radio frequency signals for car remotes much more stably, so the thinner CR1616 battery may fail in longer-distance connections.
Q: How to insert the small 16.0 mm battery into a device without damaging the internal insulation?
A: A metal screwdriver must never be inserted between the battery's top (positive) cap and the bottom (negative) edge. Even a brief touch can trigger a galvanic circuit that will irreversibly eat away the capacity. Coin elements should be installed by hand (preferably using protective gloves so as not to leave oxide stains) or with ceramic tweezers.
Q: How does the cold affect the efficiency of the CR1620 battery if a car key remote is left in the car in winter?
A: Unlike water-based alkaline batteries, the lithium manganese (Li-MnO2) CR1620 cell maintains low resistance readings even when freezing. The working temperature range allows the element to continue delivering a nominal 3.0V even at -30°C, guaranteeing the transmission of the car's immobilizer signal.
