  CHECKING AND CHARGING THE BATTERY EAS00178 ELECTRICAL SYSTEM CHECKING AND CHARGING THE BATTERY WARNING Batteries generate explosive hydrogen gas and contain electrolyte which is made of poisonous and highly caustic sulfuric acid. Therefore, always follow these preventive measures: S Wear protective eye gear when handling or working near batteries.
• Page 100
  CHECKING AND CHARGING THE BATTERY NOTE: Since MF batteries are sealed, it is not possible to check the charge state of the battery by mea- suring the specific gravity of the electrolyte. Therefore, the charge of the battery has to be checked by measuring the voltage at the battery terminals.
• Page 101
  CHECKING AND CHARGING THE BATTERY WARNING Do not quick charge a battery. CAUTION: S Make sure that the battery vent is free of ob- structions. S Never remove the MF battery sealing caps. S Do not use a high-rate battery charger. They force a high-amperage current into the battery quickly and can cause battery overheating and battery plate damage.

  CHECKING AND CHARGING THE BATTERY Charging method using a variable-voltage charger Charger Measure the open-circuit NOTE: Ammeter voltage prior to charging. Leave the battery unused for more than 30 minutes before measuring its open- circuit voltage. Connect a charger and am- NOTE: meter to the battery and Set the charging voltage to 16 X 17 V.
