RENATA CR2025 vs CR2032: Are they interchangeable?
The RENATA CR2025 and CR2032 are both lithium coin cell batteries,Classified as non-rechargeable (primary battery) .commonly used in small electronic devices like watches, calculators, and remote controls. While they share many similarities, they also have some key differences that make each more suitable for specific applications. Here's a comparison between the two:
CR2025 vs CR2032: Battery Size
CR2025 Battery size:
Diameter: 20 mm
Thickness: 2.5 mm
CR2032 Battery size:
Diameter: 20 mm
Thickness: 3.2 mm
The CR2032 is thicker than the CR2025, which is an important consideration if the battery needs to fit into a device with a specific battery compartment.
CR2025 vs CR2032: Battery Capacity
CR2025 Battery Capacity: Typically around 150 mAh (milliamp hours)
CR2032 Battery Capacity: Typically around 220 mAh
The CR2032 has a higher capacity due to its greater thickness, meaning it can last longer in devices with similar power requirements.
CR2025 vs CR2032: Battery Voltage
Both the CR2025 and CR2032 provide a nominal voltage of 3V.
CR2025 vs CR2032: Applications
CR2025: Often used in devices where space is more constrained, such as smaller remote controls, watches, and small medical devices.
CR2032: Commonly used in devices that require a longer battery life or where the battery compartment is designed for a thicker battery, such as key fobs, larger remotes, and some computer motherboards (for CMOS memory backup).
Interchangeability
In some cases, CR2025 and CR2032 batteries can be interchangeable, depending on the device. However, using a CR2025 in place of a CR2032 will result in a shorter battery life due to its lower capacity. Conversely, a CR2032 might not fit into a device designed for a CR2025 because of its greater thickness.
CR2025 vs CR2032: Price
Generally, the prices of CR2025 and CR2032 batteries are similar, though the CR2032 may sometimes be slightly more expensive due to its higher capacity.
Summary
CR2025 Price: Best for smaller devices with space constraints or where the power demand is lower.
CR2032 Price: Best for devices that require longer battery life or can accommodate the thicker battery.
