[Corolla 2022] Newbie question: is this battery corrosion? I am seeing what appears to be some wet area on the battery? It's been raining here, so I don't know if that's just water? Thanks.

Somebody sprayed anti-corrosion liquid/gel on the terminals, nothing to worry about.

Nope. In fact, someone sprayed anti-corrosion on the battery terminals to prevent that.

No. It's just dirty and stained from rain water. Nothing to worry

No, no visible corrosion. Your battery and engine bay look immaculate i really wouldnt be worried at all.

looks like water sitting on top more than actual corrosion, the terminals look pretty clean from what i can see. wipe it dry and check if it comes back, if it does then maybe the battery case has a tiny crack somewhere but that's less common on newer cars
