My car has an alarm/immobiliser and therefore has some drain. And it's not a daily driver. So - to make sure the battery's not flat when I do want to go out - I want to use a trickle charger. The workshop manual kindly explains where the 'jump start' terminals are in the engine bay.

I'm hoping I can use these, which are far more convenient, instead of trying to get to and from the battery itself whenever I want to drive/park the car.

Anyone doing this already?
