What is CR2032 Battery?
A CR2032 battery is a small, coin-shaped, non-rechargeable lithium-ion battery with a voltage of 3.0 volts. It is part of the CR (Coin or Button Cell) battery series and is a widely used power source for various small electronic devices. The "CR" in its name indicates that it uses a lithium manganese dioxide chemistry.

Key characteristics and applications of CR2032 batteries include:
1. Size: CR2032 batteries are 20mm in diameter and 3.2mm in height, giving them a compact and coin-like appearance.
2. Voltage: They provide a stable voltage of 3.0 volts, which is suitable for many electronic applications.
3. Long Shelf Life: CR2032 batteries have a long shelf life, often lasting several years when stored properly.
4. Common Uses: They are commonly used in devices such as wristwatches, calculators, key fobs, computer motherboards (for CMOS memory), remote controls, thermometers, medical devices, and various small electronics.
5. Non-Rechargeable: CR2032 batteries are not rechargeable, meaning they should be replaced when depleted rather than recharged.
6. Widely Available: They are readily available in most electronics and battery stores, making them easily replaceable.
CR2032 batteries are popular due to their reliability, compact size, and compatibility with a wide range of devices. When choosing a replacement battery, it's essential to ensure that the voltage, size, and chemistry match the specifications of the device for which it is intended.
What is CR2025 Battery?
A CR2025 battery is a small, coin-shaped, non-rechargeable lithium-ion battery with a voltage of 3.0 volts. Like the CR2032, it is part of the CR (Coin or Button Cell) battery series and is widely used in various small electronic devices. The "CR" in its name indicates that it uses a lithium manganese dioxide chemistry.

Key characteristics and applications of CR2025 batteries include:
1. Size: CR2025 batteries are 20mm in diameter and 2.5mm in height, making them relatively thin compared to other coin cell batteries.
2. Voltage: They provide a stable voltage of 3.0 volts, which is suitable for many electronic applications.
3. Long Shelf Life: CR2025 batteries have a long shelf life, often lasting several years when stored properly.
4. Common Uses: They are commonly used in devices such as wristwatches, calculators, key fobs, remote controls, small electronic toys, glucose meters, and various small electronics.
5. Non-Rechargeable: CR2025 batteries are not rechargeable, meaning they should be replaced when depleted rather than recharged.
6. Widely Available: They are readily available in most electronics and battery stores, making them easily replaceable.
CR2025 batteries are popular due to their reliability, compact size, and compatibility with a wide range of devices. When choosing a replacement battery, it's essential to ensure that the voltage, size, and chemistry match the specifications of the device for which it is intended.
