Introduction to CR1632 battery

CR1632 battery is a button type lithium battery with its thin and large characteristics, commonly used in computer motherboard CMOS batteries, other memory functions or power-off protection modules, electronic scales, calculators and other portable electronic devices.

Introduction to CR2032 battery

CR2032 battery belongs to the lithium battery structure, shaped like a button, abbreviated as button lithium battery or coin battery. It has the advantages of high specific energy, long storage life, small self discharge, safe use, and wide working temperature range. The battery can operate normally in the range of -20~+80 ℃.

CR1632 vs CR2032 Size

Before comparing their size, let's first understand their naming convention.

CR1632 battery vs CR2032 battery Size

"C" represents a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode,

"R" indicates that the battery's shape is a coin battery.

CR1632 battery: "16" and "32" respectively, represent a diameter of 16.0mm and a thickness of 3.2mm for the battery.

CR2032 battery: "20" and "32", respectively, represent a diameter of 20.0mm and a thickness of 3.2mm for the battery.

Obviously, the CR2032 battery is 4 millimeters larger in diameter than the CR1632 battery, so the two batteries cannot be replaced equivalently.

CR1632 vs CR2032 Specification Comparison

Summary of CR1632 batteries vs CR2032 batteries Specification Comparison

There is a significant difference in specifications between CR1632 batteries and CR2032 batteries.

In terms of size, the diameter of CR1632 batteries is 16mm with a thickness of 3.2mm, while the diameter of CR2032 batteries is 20mm with a thickness of 3.2mm. Obviously, CR2032 batteries have a larger diameter, but the thickness of both batteries is the same.

In terms of capacity, the capacity of CR2032 batteries is usually higher than that of CR1632 batteries because it has a larger volume to accommodate more active substances. This means that CR2032 batteries can provide longer usage time, especially in devices with high loads or continuous operation.

Both are 3V button batteries with the same operating voltage.

Before installing button batteries, it is necessary to ensure that the selected battery model and specifications match the requirements of the device to avoid incompatibility or malfunction.

● Open the cover of the battery device that needs to be replaced.

● Observe the direction of the positive and negative poles in the battery compartment, insert them into the battery compartment, usually with the positive pole facing upwards.

CR1632 lithium battery vs cr2032 lithium battery Precautions

● Do not expose the battery to high temperature environments to avoid disassembly, modification, welding, or liquid intrusion.

● Do not incinerate used batteries, recycle or dispose of them according to regulations.

● Store all batteries out of sight or reach of children.

● In case of emergency situations such as battery short circuit or leakage, safety measures should be taken promptly.

● Note that button batteries are usually disposable and cannot be charged to prevent bursting.

Safety and environmental protection

CR1632 and CR2032, both are a kind of lithium battery, they both have high safety and environmental protection. Lithium batteries adopt a closed design, which effectively prevents electrolyte leakage and reduces safety risks. At the same time, both batteries do not contain mercury, cadmium and other harmful substances, in line with environmental requirements.

Summarize

CR1632 and CR2032 batteries have significant differences in size, capacity, application scenarios, etc., so they are not considered equivalent.
