Hey all ^^
I've got a question I cannot, for the life of me, figure out.
I work at a watch and clock repair shop and am going to school for engineering. It turns out that sometimes, when I run a clock on a big name battery like Energizer or Duracell, it doesn't behave correctly, meaning it doesn't keep time, the pendulum doesn't swing but the clock works etc... However, a different brand, like Rayovac, or Kirkland will make the clock behave just fine. Keep in mind, all these batteries are new straight out of the package.
Now this could just be due to other factors than just the brand of the battery. As I haven't done any scientific testing, I have no idea. I just wanted to know if there was anything different between those brands that could cause a clock to behave poorly or even not at all.
Also, any suggestions on how to test such a hypothesis would be appreciated.
Thanks ^^
