After behaving faultlessly for years, our car failed to start two weeks
ago.
Away from home in a car park.
RAC called, and after about a 2 hour wait they turned up.
At which point the bl**dy thing started.
Anyway, battery was well old (bought car late 2016) so had a brand new battery fitted.
Today, it started fine.
Drove for about 45 minutes.
Stood for a couple of hours.
Started fine.
Drove back for 45 minutes.
Now it won't start any I can see the 12V being dragged down by something.
Until this is resolved it seems risky to use the car.
It is on charge, but the random nature of the failure suggests that it
could happen at any time.
For safety and lack of worry, I think a jump start pack would be sensible.
We have 2 vehicles; 3.0l diesel car and 2.3l diesel motor home.
I am now looking for suggestions (borne from experience) for a reliable
jump start pack.

I bought one of these from Amazon about 6 years ago in a flash sale at a large discount.
It still works well and has started various cars and diesel vans.
The largest car engine was a 6.3l Ferrari FF with a totally sulphated battery. It did struggle with that but eventually started it.

It cranks, but the displayed voltage on the voltmeter rapidly drops below
12V and the cranking stops.
Presumably a safety measure.
The voltmeter shows it charging at 14V when driving.
The car is in the garage for other work, and fortunately (?) showed the failure when they tried to move it.
So under investigation.
The interesting thing is that this failure was diagnosed as an old battery
so there is now a brand new battery in the car, fitted by the garage.

Testing across the battery terminals is difficult because the battery is under the passenger seat and you have to remove the seat to get at it.

back - I replaced the battery but that didn't solve the problem - I eventually discovered that the earth strap between the engine and the

That meant the alternator couldn't put any charge into the battery due
to the high resistance path.

To track down which fuse the parasitic load is on, a set of these

I don't think it chucks out a vast amount of charge, but is very good for maintaining battery condition.
I will have to dig around in the store of motoring related things to see

I haven't read the manual yet, but the picture on the front says 10W USB A out, and 60W USB C in.
It looks as though it needs a USB C charger capable of chucking out 60W if you want to be able to use it twice without waiting a long time for it to charge.
I do have one fast charger, but as it is for a Realme Pro phone I don't
think it uses the ususal fast charging protocol.

It's possible it wants to charge from 20V (60W = 20V @ 3A) which might
mean it won't charge at all from a phone charger. Depends whether the internal charging circuit can step up the voltage or just step down.

How do you diagnose an under performing earth strap apart from by

Dug out my old (allegedly) 8A charger (old is well pre metrication, AFAIK). It still works, but is only reporting 4A charging.
My dodgy arithmetic suggests that at 4A per hour it is putting in 4 Amp
Hours of charge.
That doesn't sound a lot for a large battery that cranks a 3 litre diesel.
Unreliable lookup suggests around 77 Ah capacity for the battery.
Call it 80 Ah just to simplify the arithmetic.
Assuming 80% charge it would need 80 - (80X.8) = 16 Ah to fully charge.
That doesn't look too bad.
Charged from 80% in 4 hours, I think.
However: <https://www.screwfix.com/c/auto-cleaning/car-battery-chargers/cat12010001? sort_by=price>
seems to offer much more powerful chargers.
There is also a very confusing maximum engine size, where for example a 6A charger shows maximum size 1.6l.
The same reported charging rate (such as 6A) also shows as 1.6l, 3l, etc.
So I am wondering if my ancient charger is suitable, or if I need
something beefier.
Compared to Screwfix, Amazon is very cheap <https://www.amazon.co.uk/Automatic-Temperature-Compensation-Motorcycle- Batteries-Red/dp/B094VQ88X2/>
However I don't recognise the brand.
Bottom line, is it time to invest in a new charger?

Charged OK from whatever is in the 13A + USB A sockets installed 12-13
years ago.
I am currently in a minefield trying to establish which of my many
devices are compatible.
I have Anker and uGreen cigar lighter socket chargers which claim to be
fast chargers.
A bit coy on which variants of signalling they support.
Mention compatible cables - but my raft of USB cables don't seem to have
that information on them.
Now looking at a Dell Laptop which has a USB C port which accepts
charging from a Power Delivery charger, but doesn.t say if the supplied charger supports Power Delivery.
I am hoping that most/all charger support the basic Power Delivery
standards and I just need to make sure I have the correct USB cable.
Then label it clearly.

It's not very quick - needs leaving on about 24h to charge from empty to
full (~50Ah battery) but you pay a lot more money for a much faster
charger.

it won't start any I can see the 12V being dragged down by something.
To track down which fuse the parasitic load is on, a set of these
multimeter leads can be handy (beware the miniature size fuses).

After behaving faultlessly for years, our car failed to start two weeks
ago.
Away from home in a car park.
RAC called, and after about a 2 hour wait they turned up.
At which point the bl**dy thing started.
Anyway, battery was well old (bought car late 2016) so had a brand new battery fitted.
Today, it started fine.
Drove for about 45 minutes.
Stood for a couple of hours.
Started fine.
Drove back for 45 minutes.
Now it won't start any I can see the 12V being dragged down by
something.
Until this is resolved it seems risky to use the car.
It is on charge, but the random nature of the failure suggests that it
could happen at any time.
For safety and lack of worry, I think a jump start pack would be
sensible.
We have 2 vehicles; 3.0l diesel car and 2.3l diesel motor home.
I am now looking for suggestions (borne from experience) for a reliable
jump start pack.

Bought a NOCO GBX45 off Amazon.
Interesting looking bit of kit.
It came mostly charged.
It doesn't come with a charger.
I haven't read the manual yet, but the picture on the front says 10W USB A out, and 60W USB C in.
It looks as though it needs a USB C charger capable of chucking out 60W if you want to be able to use it twice without waiting a long time for it to charge.
No manual - need to look on line.
