How to Take Care of Automotive Batteries
2

• Its very important to take care of your
  automotive batteries because let corrosions set
  it on your battery terminal. Once corrosion set
  in, your car will randomly fail to start due to
  electrical contact being lost between battery and
  cable. Especially with GM vehicles.

3
Step 1

• Go to the auto parts store, and acquire some
  battery terminal goo, the stuff that prevents
  corrosion. Usually comes with a new battery.
  Better yet, you can purchase some battery
  corrosion prevention spray. It does the same
  thing and is easier to apply.

Step 2

• Remove any rubber or plastic covers off of the
  battery terminals. Not the posts on top, but the
  terminals on the side that the cables bolt on to.

5
Step 3

• Do you see any blue or white powder/corrosion
  forming anywhere? If no, put the covers back on
  and crack open a beer, you're done.

Step 4

• If yes, you see corrosion, then you've got work
  to do. Remove both battery terminals with a
  socket wrench. Make sure you remove the NEGATIVE
  (black) cable first. Please watch what you're
  doing here. Don't short circuit the red terminal
  to any metal part of the engine or your going to
  be sorry. Just be cool when you ratchet the
  wrench back and forth.

Step 5

• Get a wire brush and scrape off all the
  corrosion crud from the bolt, the cable assembly
  and the battery terminal itself. Get inside the
  threads of the battery female connector. Make
  real sure you get all the crud off the cable
  assembly, including the connectors. I have had to
  cut off the rubber insulation so that I could get
  all the corrosion off. Just make sure to cut the
  rubber so that you can put it back on later. Tip
  - pour boiling water over the corrosion before
  starting any other cleaning - it will dissolve
  much of the deposits and wash them away.
  Dissolving some baking soda in the water will
  neutralize the acid in the crud. Wash down
  thoroughly with plenty of cold water afterwards.

Step 6

• Check again to make sure you've got every last
  bit of corrosion brushed off. The corrosion is
  battery acid that has reacted with the air and
  metal. If you don't get it off, it continues to
  react and cause problems. In fact some say it
  will slide down the cable assay insulation and
  force you to replace the whole assembly at
  considerable cost.

Step 7

• Once everything's hunky dory and spotless, then
  spread the goo or spray all the mating surfaces
  completely.

Step 8

• Now you're ready to put it all together. Don't
  over tighten and strip the battery threads...
  it's only soft lead after all. Put the positive
  (red) on first, then the negative (black).
