Will using the car air conditioner drain the battery?

[FaithDella]

Using the air conditioner while the car is idling can drain the battery. Here are the specific drawbacks of running the air conditioner while idling: Fuel consumption: Keeping the air conditioner on while the car is parked and idling consumes a significant amount of fuel because the compressor relies on the engine's idle operation, leading to incomplete fuel combustion and the formation of carbon deposits. Toxic substances: Incompletely burned fuel produces toxic substances such as carbon monoxide. With the car windows and doors tightly closed for an extended period, exhaust gases can enter the enclosed cabin, and when accumulated to a certain level, can cause carbon monoxide poisoning. Idling with the air conditioner on emits more harmful exhaust gases compared to driving with the air conditioner on, as the idle condition produces relatively higher amounts of harmful gases like carbon monoxide, hydrocarbons, and nitrogen oxides.
