• The battery plugs should be removed during charging.
  • The battery electrolyte level may rise and overflow from the battery during charging.
  • Explosions may occur if the battery is brought close to naked flames during charging.
  • Be careful to avoid tasks that might produce sparks or other danger while the battery is charging.
  • After charging is complete, reinstall the battery plugs, pour water over the battery to rinse away any sulphuric acid, and let the battery stand to dry.
  • Charge the battery in a well-ventilated location.
  • Do not let the battery electrolyte temperature rise above approximately 45°C (approximately 55°C during rapid charging).

1.Remove the battery from the vehicle.
2.The normal charging current is a value in amperes which is 1/10th of the battery capacity. If the battery needs to be charged rapidly because of reasons such as time limitations, the maximum charging current for rapid charging is the battery capacity expressed as an ampere value.
