• Charge batteries in a designated, well-ventilated area.
  • Do not attempt to recharge a frozen or damaged battery.
  • Follow the manufacturer’s recommendations for charging rates, connections and vent plug adjustment. Properly maintained vent caps will reduce the chance of electrolyte spray.
  • Unplug or turn the charger off before attaching or removing the clamp connections. Carefully attach the clamps in proper polarity to the battery.
  • Rinse off batteries and clean terminals before recharging.
  • Fill sulfuric acid (electrolyte) to the prescribed level before charging to reduce the possibility of the electrolyte heating up excessively. If water is added, use distilled water, not tap water.
  • Turn off the charger before disconnecting the cables from the battery.
