Battery CR2025
CR2025 Battery – Long-lasting Power for Small Electronics
Product: Lithium battery CR2025
Voltage: 3 V
A non-functioning car remote, a dead calculator, or a stopped watch often causes inconvenience at the worst possible time. The CR2025 battery is one of the most popular solutions, ensuring stable and long-term power supply for precision devices. We have tested this lithium cell and evaluated its technical characteristics and versatility.
Technical Summary (Specifications)
- Type: Lithium.
- Standard: CR2025.
- Voltage: 3 V.
- Capacity: 170 mAh.
- Dimensions: 20 mm (diameter) x 2.5 mm (thickness).
- Quantity: 1 pc.
1. Energy Density and Reliability
This lithium battery features a 170 mAh capacity, which is optimal for low energy consumption devices. Key benefits include:
- Stable Voltage: The 3V output remains constant throughout most of the discharge cycle, ensuring your devices operate without interference.
- Temperature Resistance: Lithium technology allows the battery to operate reliably in both cold and warm conditions, which is crucial for car key fobs.
- Long Shelf Life: Lithium batteries have an extremely low self-discharge rate, making them suitable for storage for several years.
2. Universal Application
CR2025 is a standard "coin" type cell, most commonly used in:
- In the Office: Calculators, laser pointers.
- Home Electronics: Remote controls, kitchen scales, LED candles.
- Personal Needs: Wristwatches, sports equipment (e.g., heart rate monitors), and car alarm remotes.
3. Physical Properties and Installation
It is important to pay attention to the exact dimensions. This coin cell is 20 mm in diameter and 2.5 mm thick. Although it is the same diameter as the popular CR2032, it is thinner, meaning other batteries will simply not fit in devices designed specifically for the CR2025. The polished stainless steel casing protects against corrosion and ensures good contact with device terminals.
Verdict
The CR2025 battery is an economical and reliable choice when looking for a high-quality power source for small electronics. It is a standard item worth keeping in a drawer for emergencies, as it guarantees long service life and flawless device performance.
Frequently Asked Questions (FAQ)
What is the difference between CR2025 and CR2032?
The main difference is the thickness: CR2025 is 2.5 mm thick, while CR2032 is 3.2 mm. Both have 3V voltage, but due to the thickness difference, they are usually not interchangeable.
How long does this battery last when not in use?
Most high-quality lithium cells retain their properties for up to 5-10 years if stored in a dry, cool place in their original packaging.
