Spent ages trying, got a kid to help her pus it onto the side, and came home.

2 hrs later - so when it's colder outside and the engine would have cooled down even more - got a taxi with jump leads up there. But the car started on the key straight away.

Can anyone explain why in simple English and what I need to know so this doesn't happen again?
It could be any number of things tbh, but the first question is when the battery appeared flat, was the engine turning over or did you just get a click on the key? Or maybe there was no reaction to turning the key at all? Dash lights?
