CR2032 3V 225mAh Lithium Coin Cell Battery

The CR2032 3V 225mAh Lithium Coin Cell Battery is the single most common coin cell format in electronics the CR2032 designation encodes its chemistry and dimensions, where CR identifies lithium manganese dioxide chemistry, 20 is the diameter in millimetres, and 32 is the height in tenths of a millimetre (3.2mm thick). That 20mm diameter and 3.2mm thickness fits the coin cell socket on virtually every RTC module, Arduino shield, and development board that includes a backup battery slot for maintaining clock and memory settings when the main power is removed.

The cr2032 3v battery have lithium chemistry holds a flat discharge curve the terminal voltage stays close to 3V through most of the 225mAh capacity before dropping sharply near the end of life. That stable voltage output keeps RTC oscillator circuits and low-power sensor nodes operating at their specified supply voltage for most of the cell’s life rather than declining gradually. At the low standby currents that RTC modules and memory backup circuits draw typically 1 to 10 microamps a single CR2032 lithium battery lasts months to years in continuous standby service.

Then 3V 225mAh lithium coin cell battery is a primary cell and cannot be recharged. Some development boards include charge circuitry that attempts to trickle-charge a coin cell slot this is safe only with rechargeable LIR2032 cells, not with the CR2032 lithium 3V coin battery which can vent or rupture if subjected to charging current. The cr2032 lithium coin cell suits RTC backup, BIOS clock retention, and low-power wireless sensor node memory backup. Available on StemVolt. This cell is working on embedded systems and practical low-power electronics projects.
