What does CR2016 mean in CR2016 Battery?
CR2016 stands for a lithium manganese dioxide battery (round shape) having a 20mm diameter and 1.6mm thickness.
- The letter C indicates the chemical composition used in the battery (here ie, Lithium Manganese Dioxide)
- The letter R indicates the shape of the battery (here ie, Round)
- The first two digits indicate the battery’s diameter in millimeters (here ie. 20mm)
- The second two digits indicate the battery’s thickness (here ie. 1.6mm)
What is a CR2016 Battery?
The CR2016 is a tiny, circular lithium coin battery. It’s based on a lithium/manganese dioxide (Li/MnO2) chemistry. It’s a tiny, lightweight ultra-compact battery that fits easily onto small gadgets like car remote keys, timepieces, calculators, and other similar gadgets.
It is easy to recognize the terminals of the CR2016 battery. The rough texture end is the negative terminal and the opposite flat surface is the positive terminal which is indicated on the battery as ‘+’.
Generally, CR2016 batteries have an operating temperature that ranges between -20℃ (-4℉) and 70°C (158°F), with a typical power capacity of approximately 90-100 mAh. They also have a maximum continuous discharge current of 1 mA, a nominal discharge current of 0.1 mA, and a maximum pulse current in the 5 mA and 15 mAh range.
The main advantage of CR2016 batteries is that they have a long shelf life, up to 10 years.
CR2016 equivalent batteries
The CR2016 can be easily replaced with DL2016, ECR2016, BR2016, DL2016B, BR2016-1W, CR2016-1W, 280-208, ECR2016, SBT11, and KCR2016. Each battery in this list has the same height, diameter, and voltage.
Some other equivalent CR2016 batteries are CR2025, CR1632, CR1620, CR1616, CR1220, and CR1216. But keep in mind that you will have to make some mechanical adjustments in order to use one of these in place of CR2032.
Note: While replacing a cell with a similar one, do not just stick to its size. It may fit the slot, but the voltage and power output must match the device’s requirements. Otherwise, it can cause severe damage to the system due to over/under discharge.
