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
attention.

• 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 VRLA (Valve Reg-
ulated Lead Acid) battery are different
from those of conventional batteries. The
VRLA (Valve Regulated Lead Acid) bat-
tery should be charged as explained in
the charging method illustrations. If the
battery is overcharged, the electrolyte
level will drop considerably. Therefore,
take special care when charging the bat-
tery.
TIP
Since VRLA (Valve Regulated Lead Acid) bat-
teries 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
measuring the voltage at the battery terminals.
1. Remove:
•Seat
• Battery cover
Refer to “GENERAL CHASSIS” on page
4-1.
2. Disconnect:
• Battery leads
(from the battery terminals)
ECA13640
First, disconnect the negative battery lead
“1”, and then positive battery lead “2”.
3. Remove:
• Battery
4. Check:
• Battery charge

a. Connect a pocket tester to the battery ter-
minals.
TIP
• The charge state of an VRLA (Valve Regu-
lated Lead Acid) battery can be checked by
measuring its open-circuit voltage (i.e., the
voltage when the positive battery 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.
• Positive tester probe →
positive battery terminal
• Negative tester probe →
negative battery terminal
Example
Open-circuit voltage = 12.0 V
Charging time = 6.5 hours
Charge of the battery = 20–30%
