CR2025 3V Lithium Cell

The CR2025 is a type of 3V lithium coin cell battery. It’s commonly used in small electronic devices that require a compact, long-lasting power source. Here’s a detailed overview of its features, uses, and specifications:

Key Features of CR2025:

1. Voltage:

• It provides a constant 3 volts of power, which is typical for lithium coin cells like the CR2032 or CR2025.

1. Size and Shape:

• The CR2025 has a 20mm diameter and is 2.5mm thick (hence the "2025" name).
• It is a small, flat, round battery, commonly used in compact devices due to its size.

1. Chemistry:

• It is a lithium battery, which gives it a high energy density, meaning it can store a significant amount of power despite its small size.
• Lithium batteries generally have a longer shelf life and are less prone to leakage compared to other types of coin cells like alkaline batteries.

1. Capacity:

• The typical capacity of a CR2025 battery is around 160 to 170 mAh (milliampere-hours). This means it can provide a continuous current of 1mA for about 160 hours, though actual battery life depends on the power consumption of the device.

1. Temperature Range:

• Lithium coin cells like the CR2025 typically operate in a wide temperature range, from around -30°C to +60°C, making them suitable for use in both cold and hot environments.

1. Shelf Life:

• The CR2025 has a long shelf life, often lasting several years (3-5 years or more) when stored properly, thanks to its stable chemistry.

Common Uses:

The CR2025 is used in a variety of devices that need a small but reliable power source. Here are some of the most common applications:

1. Watches:

• CR2025 batteries are frequently used in wristwatches, particularly digital watches, where a small and long-lasting battery is necessary.

1. Key Fobs:

• Many keyless entry systems for cars and garage doors use CR2025 batteries.

1. Remote Controls:

• Some smaller remote control devices, especially those for toys, thermometers, or garage door openers, use the CR2025.

1. Calculators:

• Many handheld calculators use CR2025 batteries due to their long life and small size.

1. Toys:

• Many children's toys (especially smaller ones) use coin cell batteries like the CR2025.

1. Fitness Trackers & Medical Devices:

• Devices like fitness trackers, heart rate monitors, or glucose meters sometimes use CR2025 cells for their compact size.

1. Motherboards/CMOS Batteries:

• Some motherboards in computers and electronic devices use a CR2025 as a backup battery for maintaining BIOS settings.

1. Hearing Aids:

• Certain hearing aids use CR2025 batteries to power their small internal electronics.

1. LED Keychains and Flashlights:

• Some novelty LED keychains or small flashlights powered by coin cells may use a CR2025.

Advantages of CR2025:

• Compact Size: Ideal for small, portable devices with limited space for a battery.
• Long Shelf Life: Up to 5-10 years in storage, making it perfect for devices that aren’t used regularly.
• Stable Voltage: Lithium coin cells provide a steady voltage over most of their lifespan.
• High Energy Density: Despite its small size, the CR2025 can power devices for extended periods.

Considerations:

• Not Rechargeable: The CR2025 is a disposable battery and cannot be recharged. When it runs out of power, it needs to be replaced.
• Compatibility: The CR2025 is often interchangeable with the similar CR2032 (which is slightly thicker) in many devices, but you should check device specifications to ensure compatibility, as a thicker battery might not fit.
