I have a 97 Jeep Cherokee Sport. I have noticed that things that are by the battery (electrical wire tubing, vacuum hose) are decaying very quickly...it's almost as if they are melting or having some sort of chemical spilled on them. I do not see any spillage, but there is a bunch of corrosion on the battery terminals that I have cleaned off many times before only to have it come back shortly.
This battery is relatively new (within the last few years). What is causing this?

I'm not claiming that this is THE answer, but a good possibility would be over-charging. Every time the battery is used to start the engine, operate the lights, or the radio, with the engine off, it is recharged when the engine is started by the alternator. Inside the alternator is a voltage regulator that recharges the battery if it's needed. Maybe the voltage regulator is sending too much current to the battery - it's getting hot - and the sulfuric acid fumes escape the top of the battery and decay and corrode items in the immediate area before the fumes dissipate. This will also shorten the life of your battery. There are still a few shops around that can make the adjustments in the alternator to correct this, if you bring in the alternator. Otherwise, you'll have to buy a new one. Good luck.

The corrosion on the battery posts is sulfuric acid and will erode anything that it comes in contact with. Put some baking soda on the posts and rinse off with fresh water. Repeat as necessary until the posts are clean.

Your battery is leaking sulphuric acid onto the nearby components. Replace the battery asap being sure to wear acid-resistant gloves while doing so.

if your battery is a few years old then it is NOT relatively new. it is on it's deathbed. keep your battery terminals clean by pouring a coke over them occasionally and start thinking about a new battery.

No matter how old your battery it shouldn't be spewing out acid unless the charging system is overcharging it. Have the charging system checked. It's probably frying your battery.
