Domino, no special requirements it's easy. As a former signaller who had to fit out FFR 110'S ( 4 x 12v 100a in series parallel) just remember neg off first, neg back on last. The amount of times I used to see arc welding was unbelievable until current flow was explained
And apologies as any egg sucking is not intended, but even now I'm amazed at how many people take the +ve off first.

Happy New Year!

Thanks for that.

No worries on the poultry, it's good to be reminded sometimes!

Trouble with that here in France is that a battery from the local factors costs at least 50% more and don't even think about taking it back, they don't want to know.

That is a problem. I have a local trade supplier i get mine from a couple of miles away. If you don't have that convenience then i suppose you have to do what you have to do.
