Air conditioning drains battery?

[Jeremy_R_Hoyt]

I would like to add a couple notes. First, sometimes accessories are wired directly to the battery. This is most likely to include the power outlets/cigarette lighter (depending on the model). I also know people who wire their radios directly to the battery so they can play them without the keys. So although I don’t see how the air conditioner could drain the battery, other electrical accessories can, in specific circumstances.
