    is the battery ( somewhere floating around in a drawer) still full or already dead?

    The jumping test.
    Drop the battery onto the table. When she starts to hop, she' out of juice. If it is a full, good battery she will fall and tilt over slowly. The reason: inside there is a jelly-like m**** which - dampens- the impact and causes the battery to fall over slowly. When the energy is consumed, however, the substance becomes solidified. This results in a lower density. Ergo: she jumps higher.

    the rolling test.
    You roll your battery on the table. As the full straight rolls out, the empty one rolls out in a slight curve...

    I am in line with 97% of buyers asked if they know the difference or can tell, of an empty or full battery. And had to admit I did not know, just from looking at it. and about the test I have heard the first time as well.

    CEM had some more devices for 1,5 and 9 volt battery's testing:
