Do you have old and new batteries lying around and you aren’t sure which is which?

To test your batteries all you need to do is find a hard surface. With the negative end down you simply drop each one individually.

This should be done from approximately 10cm above the hard surface. If the battery makes a solid sounding thud and remains standing it is charged. If the batteries bounce and fall over they are most likely dead.

    Nonsense. If in doubt I use my multimeter, but usually there is little doubt when they are flat.

    Even a flat battery will give the “correct” voltage on a multimeter, as a multimeter places only a very small load on the battery. Best to replace all the batteries in an item rather than just the one.
