CR2025
One of the most reliable 3V Lithium batteries on the market! If your thin remotes and 3D glasses require instant and stable power, the VIDEX CR2025 lithium button battery is your safest choice.
Why choose Lithium (CR) batteries:
- Pazīstama arī kā (analogi): DL2025, ECR2025.
- Perfect operation in the cold: Doesn't lose capacity even in freezing temperatures (essential for car remotes in winter).
- Massive longevity: Retains energy on the shelf and in devices for an extremely long time - ideal for background processes.
- Leakage guarantee: Industrially sealed casing that completely eliminates acid leakage.

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.
