Battery and Charging Safety Precautions

Always follow these safety precautions when charging or handling a battery.

  1. Wear eye protection when working around batteries. Batteries contain corrosive acid and produce explosive gas a byproduct of their operation. Acid on the skin should be neutralized with a solution of baking soda and water made into a paste. In case acid contacts the eyes, flush with clear water and seek medical attention immediately.
  2. Avoid flame or sparks that could ignite the hydrogen gas produced by the battery and cause an explosion. Connection and disconnection of cables to battery terminals is one of the most common causes of sparks.
  3. Always turn a battery charger off, before connecting or disconnecting the leads. When connecting the leads, connect the positive lead first, then the negative lead, to avoid sparks.
  4. When lifting a battery, use a battery carrier or lift at opposite corners of the base.
  5. Be sure there is good ventilation in a room where the battery is being charged.
  6. Do not attempt to charge or load-test a maintenance-free battery when the charge indicator dot is yellow or clear, or otherwise indicating insufficient electrolyte..
  7. Disconnect the negative battery cable if the battery is to remain in the vehicle during the charging process.
  8. Be sure the ignition switch is OFF before connecting or turning the charger ON. Sudden power surges can destroy electronic components.
  9. Use proper adapters to connect charger leads to side terminal batteries.
  10. When turning the charger ON, slowly increase the charge rate. If gassing or spewing occurs, turn the charger OFF.
