The brochure for my car, which does the same, says the energy for
restarting comes from braking stored in a supercapacitor. Battery not
involved.

There's also a new 'breed' of batteries becoming available
specifically designed to handle this, I think they're actually called
'stop/start' batteries. Yes, a quick search for 'stop start battery'
brings up loads of hits.

Batteries for the automatic stop/start system are designed for that
purpose.

My car has that system, but also has a button which disables it
temporarily (pressing it again resets it). I find it helpful to disable
it at junctions which are on a slope and you need to keep the brake on
to avoid rolling forwards or back, and/or are very busy and when a gap
appears you need to nip out quickly.

Oh yeah, are these the same super capacitors which were supposedly sold to
CB radio people to make an inadequate power supply more beefy? If so then a
lot of balderdash.

We had a Polo with this many years back when it was a very new thing. I
don't think I ever replaced the battery in a good number of years.

Not a problem with Jazz Hybrid, that starts of the "main" battery and
motor/generator, although there is a small lead acid and conventional
starter for backup.

Remember the amount of amps required to restart a hot engine (especially
one tuned for stop start) is tiny compared to a cold start on a winter's
day. And the batteries tend to have a larger capacity than a similar car
without.

Plus when the engine is stopped, the ECU ensures it stops in an ideal
position to require minimal rotation to restart.

Unless you do a lot of start/start heavy traffic driving the fuel saving
is minimal.
It was only brought in by car manufacturers to artificially reduce CO2
emiisions to comply with EU regs.

Absolutely no effect at all. The engine leaves itself primed ready to
fire and will restart again before you can even put it into gear. If the
engine isn't warm enough to support fuel saving mode it will display an
icon on the dash instead and keep running. If the engine block cools to
a point where restart might be a problem it spontaneously restarts -
which can be a little disconcerting the first time it happens to you.

Most of our driving is around town.

Failure to use the car regularly and/or only ever doing very short
journeys can be more of a problem for the battery life.

The main problem with modern electronic ignitions is that if the battery
is borderline the immobiliser can panic when the starter motor current
draw causes the battery voltage to collapse. I had that happen to me
last month and was walking home when a friend stopped picked me up and
we went with jump leads. But my solar panel recharger had actually put
just enough into the battery in the couple of hours I had been walking
to allow it to start so I should have just sat with it and waited.

My four year old Skoda Octavia with stop/start feature recently told me its battery was getting flat and a test at a specialist revealed it was indeed nearly dead. A new one was £90 which didn't seem TOO bad to me. They said batteries have an expected life of about 4 years.

I just whack the gear selector into "S" mode at tricky junctions, that

What's the point of that?
If it's easier for the alternator, it'll be easier for the starter motor too.

I had a courtesy car with that feature, it made a similar noise on automatic start to initial start. But I suppose there are various ideas about.

If you looked at the teeth on the flywheel on old cars, you could see that the engine stopped at certain places anyway.

+1, assuming you mean your ICE car.

The Bosch silver on a previous car - a BMW E39 - did 11 years. It replaced
the BMW badged one which failed just outside the car warranty at three
years.

That BMW was one of the fastest starting cars I've ever had - it seemed to
fire after going over the first compression even when cold. Which could
have made it kinder to batteries.

I bought the car at two years old. Could be the original battery had been
allowed to go flat in the showroom. It looked identical to the Bosch,
apart from the badge.

Current car takes a bit of churning.

Depending on the number of cylinders and firing order. It will usually
come to rest where a compression stroke stops it.

With a pre-engage starter, the wear pattern is much less pronounced.

Thats bull****. Alternators left generators for dead.

Dual circuit brakes left single circuit brakes for dead.

No longer using distributors was a vast improvement.

No longer having to grease joints is a big improvement.

Laminated windscreens leave the previous approach for dead.

Modern windscreen wipers leave the previous ones for dead.

Electric radiator fans leave the previous mechanical ones for dead.

Disc brakes leave drum brakes for dead.

Electric windows leave mechanical ones for dead.

to me last month and was walking home when a friend stopped picked me
up and we went with jump leads. But my solar panel recharger had
actually put just enough into the battery in the couple of hours I had
been walking to allow it to start so I should have just sat with it and
waited.

Happened to me once a few year ago, Bank holiday Friday evening just as
about o go home. I sat in the office waiting for AA not knowing the
reason why alarm and central locking appeared to have gone insane.
Cleaner came in after a couple of hours, instantly diagnosed the problem
got her jump leads out and sorted it. Took great delight in phoning back
to the AA telling them not to bother as the cleaner had fixed it. The
silence at the other end of the phone was palpable. I would have asked
her to marry me but her hubbie was ex marines.

Absolutely no effect at all. The engine leaves itself primed ready to
fire and will restart again before you can even put it into gear. If
the engine isn't warm enough to support fuel saving mode it will
display an icon on the dash instead and keep running. If the engine
block cools to a point where restart might be a problem it
spontaneously restarts - which can be a little disconcerting the first
time it happens to you.

Failure to use the car regularly and/or only ever doing very short
journeys can be more of a problem for the battery life.

The main problem with modern electronic ignitions is that if the
battery is borderline the immobiliser can panic when the starter motor
current draw causes the battery voltage to collapse. I had that happen
to me last month and was walking home when a friend stopped picked me
up and we went with jump leads. But my solar panel recharger had
actually put just enough into the battery in the couple of hours I had
