Bouncy Bouncy...

How to spot a dead battery
Quote
Ever spent ages swapping batteries in and out of remote controls to find out which ones still have power in them?
Next time, just try dropping them on a hard surface and see if they bounce.
This is because spent alkaline batteries are more likely to bounce than fresh ones, according to an American electrical engineer whose video demonstrating the phenomenon is becoming an internet sensation.

But before you throw away or your bouncing batteries:

A spokesman for the Institute of Physics said there was ‘sound thinking behind the idea’ but added: ‘Experiments need to be reproducible for results to be reliable. We’re struggling to replicate the experiment over here.’

I haven't got any dead ones to test with at the moment.
Wonder if the same test can work for rechargables Undecided

I just get my multi-meter out and check them that way... any that fall below 1.0 volts certainly get chucked .... and I don`t care if they bounce ! !    Cheesy Cheesy
