Question by Mark N: What is the difference between a battery and an 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?).

Answer by Dr.A
A galvanic cell is an electrochemical cell that stores energy and makes it available in electrical form.
A battery is a string of two o more celle in series.
An accumulator is an apparatus by means of which energy can be stored . It is a RECHARGEABLE battery

An accumulator is an energy storage device. It is a pressure storage reservoir in which a non-compressible hydraulic fluid is held under pressure by an external source. That external source can be a spring, a raised weight, or a compressed gas. The main reasons that an accumulator is used in a hydraulic system are so that the pump doesn’t need to be so large to cope with extremes of demand, so that the supply circuit can respond more quickly to any temporary demand and to smooth pulsations.
In science a galvanic cell is an electrochemical cell that stores chemical energy and makes it available in an electrical form, and a battery is a string of two or more cells in series. Formally, an electrical “battery” is a series-connected array of similar voltaic cells (“cells”)
