Trickle chargers

With all this talk of cold weather... and dead batteries... I am after some advice:
What is the best way to run the trickle charger leads to the battery in a 12R?
I obviously don't want to need to take the battery out as that's painful....
.. oh and while i am at it... does anyone clip their chargers onto the battery jumpstart cable?
