- 1). Prop up the hood of your Altima and look for the battery. It is located on the lower right hand corner of the engine compartment, right behind the driver's side head lamp.
- 2). Search the battery for any visual signs of corrosion. This is usually visible with the presence of a white or yellow powdery substance on the battery cables and on the battery itself.
- 3). Check the battery cables on your Altima for corrosion by first disconnecting them from the battery. Bend them gently. If there is a crunching feeling as you bend them, it is an indication that the battery cables have corrosion under the plastic casement.
- 4). Take a razor and cut a vertical gash in the plastic casing. Check the inside of the plastic on the battery cables in your Altima for corrosion. Signs usually include a white or yellow powder or a green discoloration on the copper wires under the plastic. If either of these are present, you should replace these cables to lengthen the life of the battery.
- 5). Test the battery cables in your Altima for tightness by grasping the ports that connect the cables to the battery with your hand. Try to move, or wiggle, the bolts. If they move, even a little, tighten them with a wrench to prevent future acid leakage and corrosion. Grasp the bolts firmly with a wrench, and turn the bolts to the right.
- 6). Try moving the battery cables in your Altima again, after tightening them the first time, to make sure they are secure.
- 7). Make a cloudy mixture of baking soda and water to remove the corrosion from your battery. You should pour the mixture onto the powder slowly, at brief intervals, until you see the powder turn brown, bubble and wash away. Once the corrosion is gone, you can rinse the battery with plain water.
