I have my 400E all polished and ready for storage and today I was installing the battery maintainer and read in the insert, "to use only in a well ventilated area". I have the car cover on with the maintainer sitting in the trunk and the lid closed...not great ventilation.

Is this just a perfunctory disclaimer, or is there another way to use this device while a car is in storage?

Thank you.
