Two 3v and a 3v button battery What is the difference?
Generally with two 3V batteries are used CR2016, the thickness is 1.6 mm * 2 = 3.2, the series voltage is 3V * 2 = 6V.
If you have been using two CR2016 3V can not use a CR2032 3V battery replacement, although the thickness is 3.2 mm, but the voltage is not the same.
With a 3V battery are used CR2032 or CR2025, the thickness is 3.2 mm or 2.5 mm, the voltage is 3V.
