NOTE:
• The charge state of an 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-circuit 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%
2. Charge:
• Battery (refer to the appropriate charging method
illustration) .
WARNING
:
Do not quick charge a battery.
NOTE:
• Never remove the MF battery sealing caps.
• Do not use a high-rate battery charger since
it forces a high-amperage current into the
battery quickly and can cause battery
overheating and battery plate damage.
• If it is impossible to regulate the charging
current on the battery charger, be careful not
to overcharge the battery.
• When charging a battery, be sure to remove
it from the vehicle. (If charging has to be done
with the battery mounted on the vehicle,
disconnect the negative battery lead from the
battery terminal).
• To reduce the chance of sparks, do not plug
in the battery charger until the battery charger
leads are connected to the battery.
• Before removing the battery charger lead clips
from the battery terminals, be sure to turn off
the battery charger.
• Make sure the battery charger lead clips are in
full contact with the battery terminal and that

they are not shorted. A corroded battery
charger lead clip may generate heat in the
contact area and a weak clip spring may cause
sparks.
• If the battery becomes hot to the touch at any
time during the charging process, disconnect
the battery charger and let the battery cool
before reconnecting it. Hot batteries can
explode!
• As shown in the following illustration, the
open-circuit voltage of an MF battery stabilizes
about 30 minutes after charging has been
completed. Therefore, wait 30 minutes after
charging is completed before measuring the
open-circuit voltage.
Charging method using a variable-current
(voltage) charger
NOTE:
• Leave the battery unused for more than 30
minutes before measuring its open-circuit
voltage.
• Set the charging voltage to 14.0 ~14.2 V. (If the
charging voltage is lower, charging will be
insufficient, if it is higher, the battery will be
over-charged.)
