CHECKING AND CHARGING THE BATTERY
WARNING
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of poi-
sonous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:
•Wear protective eye gear when handling or
working near batteries.
•Charge batteries in a well-ventilated area.
•Keep batteries away from fire, sparks or
open flames (e.g., welding equipment,
lighted cigarettes).
•DO NOT SMOKE when charging or han-
dling batteries.
•KEEP BATTERIES AND ELECTROLYTE
OUT OF REACH OF CHILDREN.
•Avoid bodily contact with electrolyte as it
can cause severe burns or permanent eye
injury.
First aid in case of bodily contact:
External
•SKIN – Wash with water.
•EYES – Flush with water for 15 minutes
and get immediate medical attention.
Internal
Drink large quantities of water or milk fol-
lowed with milk of magnesia, beaten egg or
vegetable oil. Get immediate medical atten-
tion.
•This is a sealed battery. Never remove the
sealing caps because the balance
between cells will not be maintained and
battery performance will deteriorate.
•Charging time, charging amperage and
charging voltage for a MF battery are dif-
ferent from those of conventional batter-
ies. The MF battery should be charged as
explained in the charging method illustra-
tions. If the battery is overcharged, the
electrolyte level will drop considerably.
Therefore, take special care when charg-
ing the battery.
CAUTION:

CHECKING AND CHARGING THE BATTERY
3-48
INSP
ADJ
NOTE:
Since MF batteries are sealed, it is not possible to
check the charge state of the battery by measuring
the specific gravity of the electrolyte. Therefore, the
charge of the battery has to be checked by meas-
uring the voltage at the battery terminals.
1. Remove:
•Seat
•Panel 1
2. Disconnect:
•Battery leads
(from the battery terminals)
First, disconnect the negative lead 1, then the
positive lead 2.
3. Remove:
•Battery
4. Check:
•Battery charge
CAUTION:
a. Connect a pocket tester to the battery termi-
nals.
NOTE:
•The charge state of a MF battery can be
checked by measuring its open-circuit voltage
(i.e., the voltage when the positive terminal is
disconnected).
•No charging is necessary when the open-cir-
cuit voltage equals or exceeds 12.8 V.
b. Check the charge of the battery, as shown in
the charts and the following example.
Example
c. Open-circuit voltage = 12.0 V
d. Charging time = 6.5 hours
e. Charge of the battery = 20 ~ 30 %
5. Charge:
•Battery
