Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
future corrosion.
