Scrapping old batteries

Make sure they are flat, you can get more water in if they are empty. Electrons take up the space. Thats why there is a gap above the plates. Its for the electrons normally.

And although electrons are very light, it all adds up. So when you’re charging the battery you can weigh it with sensitive scales and see how many more electrons it has to go.

I don't buy that.

 

I reckon all the electron spaces just get moved from one plate to the other, so the weight remains the same.

.....and think of all the liquid that will evaporate on charging!

Nahh...you’re filling it up with electrons from the alternator. That’s why alternators have to be serviced occasionally; they need refilling.

On the basis of all this scientific discussion i was awake the whole of last night excitedly creating my new invention.

like the eco fan it will sell well.

 

’tired of wasting time looking at meters on gadgets  you dont understand, with a torch when your batteries are flat?

Suspicious that you have to have 3 spartmotors  and then calculate the average figure ( by candlight) when they claim different readings?

 

You need the new ‘Electron flab loss battery monitoring device’

 

with the simple clip on device you can easily measure the loss of electrons from your battery. Our handy calculator then enables you to measure the percentage loss of charge, and hence how many hours you have left before you need to charge.

 

simple, no electronics to wire up, monitor when you want,  dont be a slave to that voltmeter.

 

( nb requires initialisation easily carried out at battery install time or at any point when battery full charged)

 

kit includes

All tools required

monitoring calculator

manuals

Zero calibrated specialist device. Retaining strap.

Dedicated recording system

Wot about the hydrogen electrons given off when the battery is charging? They must weigh something. ?

No, they’re lighter than air so the battery gets heavier as they leave.

Doesnt matter if they are heavier or lighter when flat ,like an eco fan measures change in stove temperature my device measures weight. Both are completely irrelevant in regard to what we are attempting to do, move hot air or measure battery state.

Im spending the $$$ already.

Them hydrogen electrons comes from all the water we keeps saying must be added before weighting them in, silly!

You could always fill em up with heavy water. That would make them heavier. (That's deuterium for the muppets on the forum).

Ah but is heavy water cheaper than lead? 

 

Tried to price check it is Asda just now but they claim not to sell it.

That is exactly the sort of question we used to ask to annoy our physics teacher!

 

Well ive managed to go through a whole professional career and into retirement without growing up much....and rarely got caught. Mind you with the pc snowflakes i wouldnt make a week now

We had a completely useless substitute physics teacher one term. When I was sent to the headmaster’s office after repeatedly asking “Yes, but how do you make an AC battery?” I discovered that our opinion of that teacher was shared by the head, who asked me to kindly bear with him until the end of term ;)

So how DO you make an AC battery then...?

 

 

I suppose the first step is decide how many Amps per hour it needs to deliver...
