CR2025 batteries provide reliable 3V power to microelectronics.
Standard 20 mm diameter coin batteries are a fundamental element for a wide range of household and professional electronics. The CR2025 model stands out with its reduced 2.5 mm thickness and provides a respectable 160mAh capacity. It guarantees a stable 3V voltage, making these lithium-manganese dioxide cells ideal for car remote controls, fitness measuring devices, and glucometers. Manufactured without heavy metals (0% mercury and cadmium), they are both safe to use and environmentally friendly. The fixed 5-year shelf life allows batteries to be stored in long-term reserves without the risk of self-discharge. Improved sealing completely eliminates the risk of electrolyte leakage.
Physical and technical advantages:
- 160mAh capacity: Excellent energy amount for 2.5 mm thick equipment.
- Anti-Leak design: A strict steel ring isolates the electrodes.
- Stable 3V voltage: Ensures precise calibration of digital measuring instruments.
Choosing lithium primary cells significantly reduces equipment calibration errors, guaranteeing flawless diagnostics. In cases where the equipment supports a thinner design with 1.6 mm thickness, you can safely switch to CR2016 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 physical dimensions of the CR2025 battery and its place in microelectronics power supply?
Q: Why is the CR2025 (instead of CR2032) format often used in heart rate monitor chest straps?
Q: Can a CR2025 battery be physically inserted into a device socket designed for a CR2032?
Q: How does the aging of a lithium CR2025 battery manifest in flat (card-type) car remotes?
Q: How long do spare CR2025 batteries retain their capacity in an unopened package?
A: The CR2025 geometry includes the classic 20.0 mm diameter and a reduced 2.5 mm thickness, which provides around 160 mAh capacity at a fixed 3.0V voltage. This slightly thinner profile (compared to the CR2032) has become the standard for large-diameter but ultra-flat equipment, such as Apple TV remote controls and active 3D glasses.
Q: Why is the CR2025 (instead of CR2032) format often used in heart rate monitor chest straps?
A: For a chest strap sensor, it is essential to minimize thickness and weight as much as possible (down to 2.5 mm) so as not to cause abrasions during intensive sports training. The VIDEX CR2025 Li-MnO2 element can continuously power Bluetooth and ANT+ wireless transmission modules during running and swimming, maintaining stability even in direct contact with body heat.
Q: Can a CR2025 battery be physically inserted into a device socket designed for a CR2032?
A: It can be inserted because both have an identical 20.0 mm diameter, but the CR2025 is 0.7 mm thinner. As a result, the contact springs will not reach sufficient pressure and the electronic circuit will break at the slightest vibration or impact, making the device's operation unstable.
Q: How does the aging of a lithium CR2025 battery manifest in flat (card-type) car remotes?
A: CR series lithium elements have a very slow voltage drop, however, at the end of discharge, the internal resistance increases sharply. The remote's basic functions (e.g., unlocking doors from a 10-meter distance) start to become unreliable, although the remote will still work from a close distance, indicating the need to replace the element.
Q: How long do spare CR2025 batteries retain their capacity in an unopened package?
A: High-purity Li-MnO2 lithium elements are subject to slow self-discharge, which in room conditions (15-20°C) does not exceed 2% per year. The manufacturer's guaranteed shelf life is 5 years, after which the battery will still retain at least 90% of its initial 160 mAh energy for safe use in measuring instruments.
