Battery or Power Cell?

by J.Peter

Tags: , , ,

One of the less glamorous things I get to do as a watchmaker is to change batteries in quartz watches. While not very glamorous, it pays well. Quartz watches rely on an electric current both for accurate timekeeping and to pulse a motor which moves the hands. Most quartz watches have either a 1.5V silver-oxide power cell or a 3V Lithium power cell. Why do I call them power cells you ask?

There must have been a watchmaker at our store who was very insistent that power cells be properly referred to as such and not batteries, because everyone calls them by there proper name.

So, you see while the battery in your car has several cells, the one in your watch is actually a single cell (not a group of them.)
