Yes, intelligent chargers with a temperature sensor strapped to the

Which are obligatory for the fast charging of lithium batteries but I
have never seen one for a lead acid.

They are used on the trolley mounted fast chargers you'll see in a
secondhand car dealer's lot. But never seen a domestic car battery
charger with one. A large domestic charger might have a peak output of
15 amps or so, and no need for a sensor at that sort of current, which
will regulate down as the battery charges anyway.

Wonder how a 150 amp car alternator gets away without sensing battery
temperature? ;-)

It doesn't. Voltage regulation means the charge tapers off. This is why
it takes a ridiculous length of time to fully charge a car battery.

Why I asked here.

The little Lidl £13 charger with a peak output of about 4 amps actually
charges a battery faster than my older Halfords one which claims 11 amps.
I assume by keeping the charge rate at maximum until the battery is full.
