I just discovered that my car's battery is flat. I won't need the car until
around the middle of next week: will it damage the battery at all to leave
it uncharged until then?

And are the home rescue services operating at the moment anyway?

Many thanks.

That's not something I can do myself, alas. It means a breakdown service

If it's one of those chargers, which will not charge unless it sees a
voltage from the battery, you will have to connect a battery in
parallel to get the charge going.

Best to get the battery on charge ASAP, the longer it is left, the less
your chances of recovering it.

I've often wondered when new cars are made it is obviously months before
they go to a customer, so how do they look after all those batteries?

VW fit a better quality dashboard solar panel to at least some models- it
is removed before delivery to the customer and, I believe, returned for
reuse.

They ( the panels) are supposedly better ( higher output) than those
typically sold for dashboard use. They do €˜escape the return loop from
time to time apparently but Ive never seen one.

I assume, in the huge car storage areas, the just have one of those
boosters and trundle it around to start them if needed. Then the dealers
charge the battery pre delivery.

Presumably if you're a car manufacturer you install a suitable socket
(fuse protected but unswitched) on the wiring loom under the dashboard.
It doesn't have to be particularly high current for a small solar

Modern cars have various "sleep" modes that power various sub systems
off after various lengths of time. AIUI there is also a deep sleep
mode that can be manually entered that effectively disconects the
battery for storeage. How you wake it back up I donno, but cars still
do have a physical key and lock.

Though to be honest even a few mA drain will knacker a battery in few
months, Solar panel maybe, plugged into the ciggy socket or ODBII?
Actually disconnect the battery when parked up on the storeage field?
Would seem better options.

Not sure they do. I've never bought a new car, but a few just secondhand
with the original battery. And that never has the same life as its
replacement. A car sitting in the showroom etc, new or used, is not good
for the battery.

I got the reverse. The last 3 cars were bought new and the
original battery lasted much longer than the replacements.
I didn’t buy the cheapest available as a replacement. And
the last two cars never did sit in any showroom either.
Both were special order for me. The second last one
with that model very hard to get so I had to accept
the color I could get. The latest one I wanted bright
yellow so that one was a special order for me and
it never sat in any showroom at all. Fresh off the

When the car batteries that I have owned have gone flat, I have had to
buy a new one. I once charged at battery, started the car, drove to
Halfords to buy a battery and then had to fit the new one to start the
car to drive home. The OP might be able to order a new one from
Europarts and then get someone to fit it.

Agreed, depending on how 'flat' (and to some degree, the chemistry of
the battery [1]).

If Bert tried to start the car and it was *just* sluggish, he may be
in with a better chance than if it wouldn't even bring up the dash
lights, for example.

Never let a lead-acid go flat.

If we are talking about real flat then I agree 100%, but it can depend
on how long it then stays flat for as to how much damage it suffers.

eg, When I designed, built and raced an electric motorbike, it wasn't
unknown for the batteries to be at well below the desired maximum of
50% discharge (so 'flat' by battery terms) but as long as I got them
back on charge again quickly, they didn't seem to suffer (I used them
all season and won the last race). ;-)

It might work afterwards but most of its
capacity will have been destroyed.

Given the above caveats, I might go as far as 'some of it's capacity
can be lost'.

And are the home rescue services operating at the moment anyway?

Yes, best tell them you need to go shopping!

I wonder if that could be covered under the vehicle maintenance
exemption?

Now might be the time to investigate battery isolator connectors or
solar chargers? I also have one of the very portable LiPo battery jump
starters that are amazing.

Why is it flat? How long have you had it, and how long is it since the
car was used for long enough to charge the battery?

Have you got anyone nearby who could jump start the car for you? You
could leave it running for a while and see if it charges the battery. If
it does, and the battery stays charged for a few days, that's good. If
it won't charge or loses its charge over a couple of days when
disconnected from the car, you need a new battery. If it runs down when
connected, maybe you left something on.

I think Halfords will fit a new battery for you. No idea how much it
would cost.

One hour should be enough as a test. Alternators are pretty efficient
even at idling revs.

From https://mechanicbase.com/electric/how-long-to-charge-a-car-battery/:
"To fully charge a battery of the size 52Ah would take about 10 hours
from dead to fully loaded, but you would probably be able to start your
car within 1 hour."

near enough to true, albeit not accurate. Just leave the charger on for a fair few hours.

I'd completely forgotten that I do in fact have a battery charger, picked up
I think at a boot fair on a whim years back, so I've no idea if it works -
I've certainly never used it for anything.

I'm not even sure that it's intended for cars: it's switchable between six
and twelve volts and is marked "Fast Charge 6 Amp". The clamps strike me as
a bit small and flimsy for a car terminals and the warning "for indoor use
only" doesn't inspire confidence either. Is it worth giving it a go, do you

That sounds like a car battery charger.
Indoor use is only because its not waterproof - it probably has
ventilation holes/slots to aid cooling. It will OK for outdoor use if

The old fashioned transformer sort *usually* had a meter, you can
recognise those because they are always in a pressed steel box with big
ventilation louvres. The modern electronic ones (typically lightly
finned aluminium extrusions as heat sinks) will have electronic
regulation and usually have a coloured light. In either case the battery
will not come to any harm if left on for a day or two.

Or you put it in the engine bay somewhere (along with the end of your
trailing lead) and lower the bonnet gently over it. ;-)

As for the clamps, they are probably more than good enough for '6
Amps' and you might not see 6 amps from it, other than possibly for a
short time at the beginning.

Yes for sure - it's a car charger. If it's a history piece it may use a selenium rectifier which like to fail & produce nasty fumes so I'd not leave it entirely unattended the first time.
