Ten steps to jump start a car
Before starting, make sure any electrical systems or devices in the vehicle with the dead battery are switched off (Lights, radio/CD, sat-nav etc).
Park the second vehicle as close to the casualty vehicle as possible, without the vehicles touching, ensuring the jump leads will comfortably reach from one battery to the other.
Ensure both vehicles engines are switched off, remove the ignition keys and open their bonnets (or boot if the battery’s located there).
Attach one end of the red jump lead to the positive terminal on the flat battery. The positive terminal will usually have a red plastic cover with a plus (+) symbol on it. Pull the cover back to access the terminal.
Then attach the other end of the red jump lead to the positive terminal of the good battery on the second vehicle.
Attach one end of the black jump lead to the negative terminal of the good battery.
Then attach the other end of the black jump lead to a good earth point on the casualty vehicle – a solid metal part of the engine is usually best.
In all my lifetime of motoring, I can't recall having ever seen that!
Start the engine of the second vehicle.
Now attempt to start the casualty vehicle. If it doesn’t start after a few attempts, it might be more serious than a flat battery. In this event, seek professional help by calling the RAC on
0330 159 1111.

It does work - presumably it is marginally easier than attaching to the terminal. A few years ago I used to leave my car lying for long periods leading to a low battery in the winter, so I bought one of those portable battery chargers and put in the boot. The instructions on it were to connect to the earth point rather than the neg terminal (and that must have been at least 10 years ago).

I bought a portable battery jump-starter last winter; one of the best purchases I've ever made. No bigger (although thicker) than an i-phone, easily fits in a glove compartment and works first time. I seldom take the car out and often get a flat battery because of it, but these starters are just the job and a must for all drivers. They are also a handy back up for charging a phone.
This is the one I bought https://www.amazon.co.uk/DBPOWER-10800mAh-Emergency-Including-Flashlight/dp/B06Y62KHSS?ref=pf_ov_at_pdctrvw_dp |
