The Lithium CR2032 Battery For Watch and Calculator
All of the pictured portable electronic devices are powered by the same common affordable lithium CR2032 battery. The CR2032 battery is about the size of a nickle and provides five years of power for watches and calculators. Batteries can be swapped between devices in the event of battery failure. The CR2032 has a longer than average shelf life so spares will have plenty of voltage when needed. Device battery type is as important as function for making the grade at the chart table.
