2009 Ford Victoria battery pollution bullets

For sale to anyone interested, battery pollution bullets, two batteries, I emptied them, the motor got slightly hot, and I visited more than one workshop; they said the batteries are sealed. I went to a spare parts shop, confirmed it, opened them, cut the batteries, and found them clean with nothing inside. The heat persists after emptying. I recently discovered that the radiator cap was damaged, replaced it, and now it's fixed. Advice: don't rush to empty the batteries.
