The 10 year battery life – myth or reality?

I used to design products for a utility meter manufacturer. Their standard battery life warranty was for twenty years. However, anything over ten years was pro-rated based on the service life after the ten year mark. The installation cost outweighs the cost of the more expensive battery technology, so the utility company didn't want to have to replace the battery before the meter was past it's useful lifetime.

But do you really need such a lifetime? To me it seems that this 10 years is just a shiny number representing that you will not have to think about replacing the battery of your device at all. After 3-5 years you will probably not need the device anymore anyway.

10 year battery life is achievable, given the right battery type. With some batteries, the self discharge alone will fully discharge them in less than 10 years. And yes, you need to be careful of the meter used to measure the current.

All I can say is that I kept a battery in a small AM/FM radio for about fifteen years and it still worked.
