A Mishandling the battery shortens the service life and
adds to maintenance costs.
The original battery is maintenance free, but needs
some servicing.
If the battery is weak, the engine will be difficult to start
and the lights will be dim. It is important to check the
battery periodically.
A When exchanging an old battery for new one, use
battery of equal specification in table below.

(For non-accessible maintenance-free type batteries.)
Maintenance-free, non-accessible batteries are designed
to eliminate the need to add water. Yet the volume of
electrolyte above plates may eventually become depleted
due to abnormal conditions such as high heat or improper
regulator setting. Use a voltmeter to check the state of
charge. (See reference chart below to determine if
charging is necessary.)

C Battery Charging
To avoid serious injury or death:
A When the battery is being activated, hydrogen
and oxygen gases in the battery are extremely
explosive. Keep open sparks and flames away
from the battery at all times, especially when
charging the battery.
To avoid serious injury:
A When disconnecting the cable from the battery,
start with the negative terminal first. When
connecting the cable to the battery, start with
the positive terminal first.
A Never check battery charge by placing a metal
object across the posts.
Use a voltmeter or hydrometer.

(1) Battery
1. Park the vehicle on a flat surface.
2. Stop the engine.
3. Remove the battery cover.
4. To slow charge the battery, connect the battery
positive terminal to the charger positive terminal and
the negative to the negative, then recharge in the
standard fashion.
5. A boost charge is only for emergencies. It will partially
charge the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to
recharge the battery as early as possible.
Failure to do this will shorten the battery's service life.
6. When exchanging an old battery for a new one, use
battery of equal specification shown in table 1.
C Direction for Storage
1. When storing the vehicle for a long period, remove the
battery from vehicle, adjust the electrolyte to the
proper level (refillable type only) and store in a dry
place out of direct sunlight.
2. The battery self-discharges while it is stored.
Recharge it once every 3 months in hot seasons and
once every 6 months in cold seasons.
