Cleaning Battery Terminals

Most batteries are not sold with instructions. However, warnings are frequently
noted on the cell caps. Read them carefully.
DO NOT allow the liquid in the battery to come in contact with skin, clothes or
other possessions. It is a form of acid and harmful or damaging burns may result.
Should the liquid touch your skin, wash the area IMMEDIATELY and thoroughly
with cool water. In serious cases or if eye contact is made, seek medical attention
IMMEDIATELY.
1. Examine battery clamps and terminals for corrosion.
2. Verify the plastic caps are in place over battery cell holes.
3. Clean terminals and inside battery clamps by using a battery cleaning tool, wire brush,
or medium grade sand paper.
NOTE: Upon completion, areas should be shiny, not dull.
4. Carefully dust off all metal particles.
