Synergy CR2016 3V Lithium Battery Variable Voltage Regulator Hence we can use thisThe Synergy CR2016 Lithium Coin Cell is a high capacity replacement battery that's commonly found in calculators, heart rate monitors, remote starters, thermometers, and other tiny electronic devices. This small size battery is made up of Lithium Manganese Dioxide chemistry that not only supplies the cell with the high voltage required for high performance devices but also has a very low self discharge rate, extending the battery's shelf life.
