What is the difference between a battery and a acumulator?

Question by Mark N: What is the difference between a battery and a acumulator?
I would like to know with scientific base what is the difference between the two. I know that a battery cannot be recharged (the kind we use for our portable radios and flashlight that you have to throw away after depleted), and a accumulator can be recharged (like a car "battery" - wrongly named?).

A battery is simply a collection of cells which may or may not be rechargeable. An accumulator is a rechargeable battery.

For example a 9V battery has 6 of 1.5 V dry cells connected in series to give 9V. It is not rechargeable. However a 12V Lead Acid battery will have 6 lead acid cells of 2V each so that we get 12V. And that will be an accumulator.
