Will it damage the hybrid battery if I blow water mist into the ventilation duct?

As Dogman states, recycled mode still allows some fresh air which is enough for the hv battery. The battery is not a human; it does not require or need 75f-90f temperatures. I prefer 75f so the battery does benefit while I am in the car. I have never seen recycle mode dropout even though it is possible. Given the car will increase the battery fan as needed the only concern is when a dog is allowed to shed hair on the back seat which ends up in the blower wheel.

The AC system still pumps out cold air even after 13 years and 310,000 miles.
