CR1620 batteries provide reliable 3V power to microelectronics.

CR1620 lithium cells offer a 70mAh capacity in a highly restricted 16 mm x 2.0 mm format. This provides the necessary 3V voltage for small alarm remotes, computer memory boards, and specific medical equipment. They maintain a reliable discharge curve even during high-intensity pulse transmission. The integrated Anti-Leak technology encapsulates the chemistry in a steel shell, which means absolute safety against rusting or damaging the device casing. Thanks to the 5-year storage guarantee, it is a safe investment for far-sighted spare parts supply.

Physical and technical advantages:

70mAh capacity: Effective reserve for computer memory systems.
2.0 mm thickness: Guarantees easy insertion into precision mechanics without snagging.
Long standby: 5-year storage blocks energy loss.

Reliable microbatteries provide a long service life and precise preservation of technological data. For devices that require a highly precise 1.6 mm profile without compromises in energy loss, a reliable solution will be CR1616 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 parameters of the CR1620 battery and its most common everyday application?

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.
