Hey Veeky Forums whats the best way to clean corroded battery terminals/connecting wire thing?

>is this why im having a hard time starting my car?
Corrosion is a classic problem in making for sluggish starts. If you have a modern digital battery charger, it can give you a rough idea as to the state of charge of the battery.

Usually, when the acid is leaking upwards between the posts and the body of the battery, the seals there have failed. And it's time to get a new battery expecially if it's in warranty. OEM batteries don't have much of a warranty though once they are out of that magical 3 year bumper to bumper new car warranty that so many people crave for that magic new car feeling.

just get a new battery. if it's doing that it's on its last legs.

you want an agm battery. like an optima or duracell or autocraft

theyre all the same shit battery, only difference being exterior design and warrsnty length.

penetrating oil and a wire brush

Larger group size batteries tend to cost more. Just make sure the replacement you buy matches or exceeds the CCA of the factory battery. Im guessing your Vulva takes an H6/H7/H8 group size.
Corrosion? Baking soda solution with water does wonders if you soak the battery leads in it.

Is that a six volt car battery?

Lol looks like a golf cart battery

Wait is the battery from 2009? If so then it's definitely time for a new one.

The service power steering message is likely due to under-voltage to that control module, there's probably nothing wrong with it.

Replace the battery, it's obviously crystallized.
