Neighbours are away for a month but they told us before they went they'd asked friends / relatives to pop over to give their cars a bit of a run to make sure the batteries don't go flat.

Neither of their cars have moved for 2 weeks now and out of the blue today someone turned up. First car is a reasonably modern Renault and fired up on the first turn of the key. No sooner had it started, then the guy proceeded to rev it well into the 4-5k range a couple of times before letting it idle and then turned his attention to their old Pug diesel. Now I've heard the car starting and it does always take a good 5-10 seconds of cranking before it finally splutters into life. Chap repeatedly tries to start it, but lets off the ignition after 1 second so it never gets a chance to go.. after trying this for no less than 2 minutes continually (and the starter going slower and slower as the battery drains), he finally lets it crank for a bit longer before it splutters into life. The same immediate high revving whilst the engine is stone cold.

Then lets them both idle for about 5 minutes before stopping them and buggering off.

So - to summarise. A quick high revving whilst the oil is absolutely stone cold on a winters morning, and gives them about 5 minutes to idle... yeah, that'll really replenish the power wasted trying to get them to start.

The British population need more education when it comes to the basics of motoring!

Some bloke on the BBC news yesterday stated that "the AA advise people to start their cars" if they haven't used them over the last few days due to weather. This will prevent flat batteries.

nuts

Even my missus raised an eyebrow at this.

Which begs the question: how long should you run your car in order to "replenish the battery"?

6 minutes. Only rev it when cold. make sure the heater is on and loads of electrical devices like the stereo.

Old man ferkle always used to tell me 6 miles of normal driving to a start. I have always gone with this based on no evidence for or against. I suspect it depends on the car, battery an charging circuit. still dad knows best.
