Checking your battery connection to make sure your battery is being properly maintained takes about 20 minutes to do and will cost around 60 (the price of a wire brush). Here is how to do it:
1) Remove the battery cables from your battery, starting with the negative cables first.
2) Clean the posts using a wire brush and corrosion removal fluid, which is basically a mixture of baking soda and water. Save even more money by making this solution on your own.
3) Clean the battery terminals with a wire brush.
4) Rinse the cleaning fluid with water and dry with a rag.
5) Re-install your battery terminals starting with the positive ones first.
