Current reversal in 2 connected car batteries?

Unless, of course, it's self-superiority _by_ Americans.

I don't speak nor write British, though...

Yup. I don't have a problem with my inability since British or English is not my first language, fortunately I have a spellchecker that can help me out with most things...

Why cant we just all get along?

Not quite. Since 'bastardised forms' is a plural none, the correct reference would be "There are" or "There're". You used "There's" which is a contraction of "There is", which is meant for use with singular objects, not plural ones.

Even 'American's can spot that error in your English.

Talk to most Americans and they won't hear you. After September

11 2001, they didn't hear a word of the responses to the query "Why do they hate us so?"

Is this from a limey newspaper?

A simple model to understand how a car (or other rechargeable) battery works is:

Batteries work by having two chemical reactions running - one at the negative terminal, one at the positive terminal. The one at the negative terminal releases electrons and the one at the positive terminal absorbs them. Unless the electrons can get from the negative to the positive terminal, both reactions are "on hold". Connect a wire between the terminals, the electrons flow, and all is well. When the reactions at each terminal have run their course, the battery can be thought of as discharged (it is a bit more complex than that but the idea is OK at this level).

Thus far the model works for a non-rechargeable battery as well.

In a rechargeable battery, forcing electrons into the neagtive terminal, and sucking them out of the positive terminal reverses both reactions and the battery is recharged and the cycle can be repeated.

I don't know, I neither live there nor read their papers.

----------------------- I am curious about two things. a) Yorkshire is part of England- what language is spoken there? b)What has all this to do with electrical engineering?

As a Canadian, eh, I can cope with both US and British English. I don't pretend to understand Yorkshire, Newfoundland, or Ozark dialects.

I've no idea, it's a curious blend of languages...

Depends. Do you want to borrow anything, or do you come from Lancashire?

Nowt. No Yorkshireman would have anything to do with the Devil's Work.

But can you cope with those fellow countryman who pretend to speak French?

You know what I hated about the movie "An American Werewolf in London"? Trying to understand the bloody accents of the chaps in the little bar room. I suppose that was english, I mean it WAS in England and all, so what else could it had been?

Let me expand this discussion slightly. If the "fresh" battery is connected to a charger such as a car alternator, then leaving it for a few minutes to get some charge into it is a great idea.

However, if it is just a fully charged battery it cannot under any circumstances charge the dead battery. You need at least 12.9 volts to get the battery chemistry flowing in the right direction, but the voltage of even a fully charged battery will not be this high.

Look, does it make a bang and smoke and sparks or not???

I disagree. I have accompished charging one battery that was drained by paralleling it with another battery of like construction. But for the most part, what you say is valid. The drained battery was not overdrained to where it might be damaged, and it didn't get anywhere near a half charge from the connection. But it did charge enough to see some voltage from it again. Of course, the ideal is to have enough voltage to keep charging current flowing up to full charge. But to say such charging simply cannot even get started from battery to battery is just not consistent with my experience.
