Is a dead battery = a burned out battery? Can I say both “My battery is dead / burned out. Can you jump-start my car?” Maybe not, but I'm not sure. “Dead battery” = no electricity left, but if it's an EV and is a rechargeable battery, you can recharge it, correct? “Burned out battery” = no electricity left, and even if it's an EV an a rechargeable battery, you can no longer recharge it, correct? If the car battery and any other battery can't be talked about with the same words/phrases to describe them, could you tell me what kind of battery you are talking about? I want to know about the car batteries but it would be helpful too. Thank you.
