CR Baterijas (Lithium)
When it comes to the latest car keys, computer motherboards (CMOS), precise kitchen scales, and glucometers, Lithium button batteries like the popular CR2032 are indispensable. The VIDEX CR series offers outstanding reliability and extreme longevity.
Why choose Lithium batteries for scales and remotes:
- Extreme longevity: Lithium technology provides a long service life and excellent shelf life. Ideal for devices that run in the background for years.
- Stability in the cold: Lithium does not lose power in freezing temperatures (perfect if you leave your car remote in a cold jacket pocket).
- Safety and anti-leak guarantee: Protects your delicate electronics.
Trust your keys, scales, and medical devices to a reliable brand. Buy at open tools and save money in the long run!
Q: What is the technical difference between CR lithium batteries and standard alkaline (LR) coin cells?
Q: How do storage conditions affect the actual service life of CR lithium batteries?
Q: Why are CR series lithium elements specifically used in outdoor meteorological sensors in winter?
Q: How to interpret the numbers included in the CR series marking, such as CR2032 or CR1220?
Q: Why is it strictly forbidden to attempt to recharge a discharged CR lithium (Primary Lithium) battery?
A: The CR series batteries use lithium manganese dioxide (Li-MnO2) electrochemistry, which provides a fixed 3.0V nominal voltage. Standard alkaline (LR) or silver oxide (SR) elements only provide 1.5V. This 3.0V architecture allows replacing two series-connected coin batteries with a single compact CR element in computer motherboards and car fobs.
Q: How do storage conditions affect the actual service life of CR lithium batteries?
A: The dry Li-MnO2 electrochemical system guarantees a 5-year shelf life with a minimal <2% annual self-discharge. Unlike water-based alkaline electrolytes, lithium cells do not suffer from galvanic corrosion in indoor conditions (15-25°C). The VIDEX CR series retains at least 90% of its initial capacity even after a full 5-year storage cycle.
Q: Why are CR series lithium elements specifically used in outdoor meteorological sensors in winter?
A: CR lithium cells do not contain water electrolyte that could freeze, so their internal resistance remains low even in extreme sub-zero conditions. This technology ensures stable voltage output and data transmission in a temperature range from -30°C to +60°C, which is critically important in the outdoor conditions of the Baltic climate.
Q: How to interpret the numbers included in the CR series marking, such as CR2032 or CR1220?
A: The IEC standard marking precisely indicates the battery's physical geometry in millimeters and tenths of a millimeter. The first two digits indicate the diameter (e.g., 20 = 20.0 mm), while the last two indicate the thickness (e.g., 32 = 3.2 mm, 20 = 2.0 mm). Inserting an element of the wrong thickness can irreversibly deform the micro-device's contact springs.
Q: Why is it strictly forbidden to attempt to recharge a discharged CR lithium (Primary Lithium) battery?
A: CR batteries (Primary Lithium) are non-reversible single-use cells without charging chemistry. Attempting to supply them with reverse charging current releases lithium gases and rapidly raises the internal pressure, which inevitably causes a casing rupture or thermal explosion followed by ignition.
