To minimize damage to the battery and allow the battery to charge fully, use the
following slow charging procedure. You can accomplish this charging procedure
with a constant current battery charger that is available locally.
Follow the manufacturer's instructions when using a battery charger.
Note: When using a maintainable battery, using the specific gravity of the battery
cells is the most accurate procedure of determining the battery condition.
1. When using a maintainable battery, use
to determine the battery charge level from the specific gravity of the battery
cells or open circuit voltage.
2. Use the manufacturer's battery charger instructions or
(page 6–33) to determine the charging time and rate.
Charging a frozen battery can cause explosion and can cause
personal injury. Let the battery warm to 15°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 terminals.
3. Follow the battery charger manufacturer's instructions, connect the charger
cables to the battery terminals. Ensure that you make a good connection
4. Charge the battery following the manufacturer's instructions.
5. When using a maintainable battery, 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 the charge rate or
temporarily stop charging the battery.
