Exercise caution when handling batteries!
Batteries contain sulfuric acid and produce mixtures of hydrogen and oxygen. The self-discharge action of a battery generates hydrogen gas, which has the potential to explode even if the battery is not in operation. Plus, acid in the battery can cause serious burns to your skin through simple handling. That’s why it’s extremely important to follow these safety precautions:
Storing batteries
-
Store batteries in a well-ventilated, cool, open area.
-
Check batteries frequently for acid leakage or corrosion.
-
Keep a charged fire extinguisher next to stored batteries.
Handling batteries
-
Wear proper eye, face, and hand protection.
-
Keep batteries away from flames or sparks.
-
Do not remove damaged vent caps.
-
Cover caps with damp cloth to minimize gas seepage.
-
Never lean over a battery when charging or testing.
Battery installation procedures
– Disconnect the ground cable first (this is usually the negative cable; however, older vehicles may have a positive ground).
– Remove the old battery — note position of the positive (+) terminal and the negative (–) terminal. Mark the cable for the correct connection to the new battery.
– Clean the terminals and cable connections with a wire brush. Broken connections and frayed or cut cables should be replaced.
– Install the new battery in the same position as the old one; be sure to secure it with the hold-down assembly.
– Make sure the terminals do not touch any metal mounting, engine, or vehicle body parts.
– Connect the ground cable last to avoid sparks. Make sure the cables are connected tightly.
