Factory Activated MF Battery Safe Use Precautions
I. Warning
- The electrolyte inside the battery is corrosive and may damage metal, cotton products, and stone. Handle the battery properly.
- Do NOT place the battery on its side or upside down to prevent acid leakage.
- Hydrogen gas may be generated during battery operation and charging. If exposed to fire or sparks, it may cause an explosion. Please observe the following precautions:
- Use and maintain the battery in a well-ventilated area.
- Keep sparks and open flames away during battery maintenance.
- If the battery is charged outside the vehicle, do not install it immediately after charging. Let it rest for at least 10 minutes to allow hydrogen gas to dissipate.
- After riding, do not remove the battery immediately. Let it rest for at least 10 minutes.
- During charging, the ambient temperature should not exceed 45°C. If it does, cool the battery with water or reduce the charging current and voltage.
- Do NOT place metal tools or conductive materials near the terminals to avoid short-circuiting.
- Do NOT strike the terminals with a hammer during battery installation.
- Handle the battery carefully during transportation to avoid impact or damage.
II. Factory Activated MF Battery Installation and Maintenance
- Connect the positive terminal first. Do NOT reverse the polarity, otherwise the motorcycle’s electrical equipment may be damaged.
- Activation Notice:
- Some batteries may not be activated immediately due to differences in vehicle performance. Start the engine several times or gently apply the throttle to help activate the battery more easily.
- Manual activation is recommended to ensure the exact activation date is recorded.
- During acid filling, wear acid-resistant clothing, rubber boots, safety goggles, and rubber gloves. If acid splashes onto skin or clothing, rinse immediately with a large amount of water. Seek medical attention if necessary.
- Do NOT over-discharge the battery. Recharge the battery promptly after it has been discharged.
- Disconnect the negative terminal if the motorcycle will not be used for a long period.
- Do NOT check whether the battery has power by short-circuiting the terminals.
- Regularly check the terminal connections and ensure the terminals are clean to maintain good contact.
- Store the battery in a dry, well-ventilated place at 5–25°C, away from direct sunlight. Keep the battery at least 2 meters away from heat sources. Check and maintain the battery regularly.
