Charging a frozen battery can cause explosion and can cause
personal injury. Let the battery warm to 15.5°C (60°F) before
connecting to a charger.
• Charge the battery in a well-ventilated place to dissipate the
gases produced from the charging.
• These gases are explosive; keep open flame and electrical
spark away from the battery. Do not smoke.
• Inhaling the battery gases can cause nausea.
• Unplug the charger from the electrical outlet before connecting
or disconnecting the charger leads from the battery posts.
3. Follow the battery charger manufacturer's instructions, connect the charger
cables to the battery posts. Ensure that you make a good connection.
4. Charge the battery following the manufacturer's instructions.
5. Occasionally check the temperature of the battery-electrolyte. If the
temperature is more than 52°C (125°F) or the electrolyte is violently gassing
or spewing, lower and temporarily stop the charging rate.
6. Three hours before the end of the charging, measure the specific gravity of a
battery cell once per hour.
