Ah, did you know that a blown light bulb bounces and a good one doesn't,😊
I've found it's the easiest way to test if you are unsure😂

That reminds me of Dad's method of testing matches, you simply run it along the side of the box amd if it bursts into flame its a good one, so you blow it out and put it back in the box!! :-D

If you have two AA batteries, one of which has a full charge and the other has no charge, if you drop them at the same time onto a hard surface the 'empty' battery will bounce higher. Strange but true! (This will work for other batteries).

Try that with car batteries you'll have acid on your feet. :)

OK, I should have added "This will work for other portable device, non-rechargeable replaceable batteries".
