CR1632 vs CR2032: Are CR1632 and CR2032 battery equivalent?
In the daily use of electronic devices, we often encounter various models of button batteries, of which lithium material batteries CR1632 and CR2032 are two commonl specifications. Although they all look like coin shapes, an in-depth comparison will reveal that these two batteries are not exactly equivalent. In this article, we will make a detailed comparison of CR1632 and CR2032 from various perspectives, such as size, capacity, application scenarios, etc., in order to help readers better identify and choose the right battery.
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
| Model no | Size | Voltage | Capacity | Operation temperature | Weight | Material | Shape | Life | |
| Diameter | Thickness | ||||||||
| CR1632 | 16 mm | 3.2 mm | 3V | 130 mA | -20°C ~ 70°C | 1.9g | Lithium Manganese | Button Battery | 5 - 8 Years |
| CR2032 | 20mm | 3.2mm | 3V | 230 mA | -20°C ~ 70°C | 2.8g | Lithium Manganese | Button Battery | 5 - 8 Years |
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.
