What are CR2032 Batteries? Uses, Lifespan, Voltage | Arrow
Here we see that if the CR2032 battery is tasked with providing 0.5 mA (500 microamps) continuously, its output voltage will not deteriorate to 1.6 volts until it has provided 240 mAh. If on the other hand, it must provide 3.0 mA, it can only provide 155 mAh.
4.4.3Open-circuit voltage: Test specimen batteries shall be kept for 8 hours or longer at the ambient temperature specified in Table 1, and then the voltage between both terminals shall be measured at the same ambient temperature with a voltmeter as specified in Subparagraph 4.3.2.
The nominal voltage of the CR2032 battery is 3.0 V, and the cutoff voltage is 2.0 V. Capacity The coulometric capacity is the total Amp-hours available when the battery is discharged at a certain discharge current from 100% SOC to the cut-off voltage.
What is the CR2032 flat, nominal and full voltage?
The voltage at which a CR2032 battery is considered flat, (or dead) lies between 2.7 – 2.8 volts. The CR2032 battery is a primary battery which means that it cannot be recharged. So, if the battery goes flat, it will need to be replaced with a new CR2032 battery.
