BATTERY
SERVICE INFORMATION
GENERAL
• The battery gives off explosive gases; keep sparks, flames and cigarettes away. Provide adequate ventilation when
charging.
• The battery contains sulfuric acid (electrolyte). Contact with skin or eyes may cause severe burns. Wear protective clothing
and a face shield.
— If electrolyte gets on your skin, flush with water.
— If electrolyte gets in your eyes, flush with water for at least 15 minutes and call a physician.
• Electrolyte is poisonous.
— If swallowed, drink large quantities of water or milk and follow with milk of magnesia or vegetable oil and call a
physician.
• KEEP OUT OF REACH OF CHILDREN.
• Always turn "off" the ignition switch before disconnecting any electrical component.
• If the breather tube is blocked, the battery's internal pressure will not be relieved the breather may come off, or the battery may
crack as a result.
• Some electrical components may be damaged if terminals or connectors are connected or disconnected while the ignition
switch is "ON" and current is present.
• For extended storage, remove the battery, give it a full charge, and store it in a cool, dry space. For maximum service life,
charge the stored battery every two weeks.
• For a battery remaining in a stored scooter, disconnect the negative battery cable from the battery terminal.
• Tap water will shorten the service life of the battery.
• Immediately wash off any spilled electrolyte.
• Avoid filling the battery above the UPPER LEVEL line to prevent an electrolyte overflow which could corrode the engine or
nearby parts.
• The battery can be damaged if over charged or undercharged, or if left to discharge for long period. These same conditions
contribute to shorting the "life span" of the battery. Even under normal use, the performance of the battery deteriorates after
2–3 years.
• Battery voltage may recover after battery charging, but under heavy load, battery voltage will drop quickly and eventually die out.
For this reason, the charging system is often suspected to be the problem. Battery overcharge often results in problems in the
battery itself, which may appear to be an overcharge symptom. If one of the battery cells is shorted and battery voltage does
not increase, the regulator/rectifier supplies excess voltage to the battery. Under these conditions, the electrolyte level goes
down quickly.
• Before troubleshooting the charging system, check for proper use and maintenance of the battery. Check if the
battery is frequently under heavy load, such as having the headlight and taillight ON for long periods of time without riding the
scooter.
