CHECK
M1541000900364
CAUTION
• If the battery is used with the electrolyte level
below the LOWER LEVEL indicator, there is
the danger that explosions may occur, so add
water to the battery until the electrolyte level
is between the LOWER LEVEL and UPPER
LEVEL indications.

If too much water is added to make the level
rise above the UPPER LEVEL indication, the
electrolyte may leak out, so adjust so that the
electrolyte level is between the LOWER
LEVEL and UPPER LEVEL indications.
1. Check that the battery electrolyte level is between
the UPPER LEVEL and LOWER LEVEL
indications.
2. Use a specific gravity meter and a thermometer to
measure the specific gravity.
Standard value: 1.220
− 1.290 (electrolyte
temperature 20
°C)
The specific gravity of the battery electrolyte
changes according to the temperature, so the spe-
cific gravity when the electrolyte is at a temperature
of 20
°C can be calculated using the following for-
mula. Use the converted value to judge whether the
electrolyte is okay or not.

: Specific gravity converted to a value for
electrolyte temperature of 20

t: Electrolyte temperature at the time of
measurement

CHARGING
M1541001102185
CAUTION
• 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 charg-
ing.
• Be careful to avoid tasks that might produce
sparks or other danger while the battery is
charging.
• After charging is complete, reinstall the bat-
tery plugs, pour water over the battery to
rinse away any sulphuric acid, and let the bat-
tery stand to dry.
• Charge the battery in a well-ventilated loca-
tion.
• 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.
