I think that's fine if you're storing the car for long periods (re: winter), but leaving it in the car with the trickle charger on has not been deleterious as far as I know??? (re: unless you leave it plugged for days---although leaving the charger on for days is not good for the battery in either case) ... thawing out the battery in extreme cold conditions would be another reason I could think of at the moment that is also recommended ??? But again, ....never had a problem with leaving the battery hooked up in the car while using the trickle charger....
Sorry for any confusion. I meant to disconnect the car's cables from the battery. This is to keep current draw on the charger from burning up the charger more than anything else.

I agree that you don't need to remove the battery from the car. I leave my battery attached to a battery tender in the car all winter. I've seen recommendations of removing the battery from the car to reduce the risk of hydrogen and oxygen gas build-up while charging, but if the car's in a ventilated area and the vent tube is left attached, there's not issues.
