• 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
attention.

CAUTION:
• 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 an 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.
NOTE:
Since MF batteries are sealed, it is not possi-
ble to check the charge state of the battery by
measuring the specific gravity of the electro-
lyte. Therefore, the charge of the battery has to
be checked by measuring the voltage at the
battery terminals.
1. Remove:
• Rider and passenger seat
2. Disconnect:
• Battery leads
(from the battery terminals)
ECA13640
CAUTION:
First, disconnect the negative battery lead
"1", and then positive battery lead "2".

a. Connect a pocket tester to the battery ter-
minals.
• Positive tester probe →
positive battery terminal
• Negative tester probe →
negative battery terminal
NOTE:
• The charge state of an MF battery can be
checked by measuring its open-circuit volt-
age (i.e., the voltage when the positive bat-
tery 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
Open-circuit voltage = 12.0 V
Charging time = 6.5 hours
Charge of the battery = 20–30%

WARNING
Do not quick charge a battery.

CAUTION:
• Never remove the MF battery sealing
caps.
• Do not use a high-rate battery charger
since it forces a high-amperage current
