Considering this, is corrosion a sign of a bad battery?

Corrosion on the battery One of the most common symptoms of a battery terminal issue is visible corrosion. Since the terminals are in direct contact with the battery they are exposed to the acidic fumes from the battery acid and as a result are prone to developing corrosion.

Also Know, what causes batteries to corrode? Battery corrosion is caused by hydrogen gas being released from the sulfuric acid inside the battery. As the gasses react to the ambient atmosphere, it begins to produce a corrosive environment. If battery corrosion is present on the positive battery terminal, this is a symptom of overcharging.

Herein, why do batteries corrode in remote?

Editor: The most common cause of batteries leaking potassium hydroxide (which is actually an alkaline, not an acid) is simply leaving old batteries inside devices for too long. If you need to clean off the “battery acid”, be sure to wear protective gloves while doing so.

Warning Light.

Can a loose battery terminal cause a misfire?

A bad battery terminal CAN cause it, it's not impossible, but doubtfully because all the battery would have to have such a dramatic voltage spike in order to cause components to cause misfire, plus it'd have to happen more than once in order to fire up that CEL.

How do you know if its the alternator or the battery?

First, the battery delivers a jolt of electricity to the starter. If the engine starts but dies immediately, your alternator probably isn't keeping your battery charged.
