What are the common faults and solutions of lead-acid scooters?

1. Battery problem
The battery cannot be charged
Reason: Damaged charger, loose or corroded charging interface, internal battery fault.
Solution: Check whether the charger is working properly, and try to replace the charger. If the charger is normal, check whether the charging interface is loose, and tighten it if it is loose; if the interface is corroded, clean the corrosive material. If none of the above methods can solve the problem, it may be that there is a fault inside the battery, and a professional is required to inspect or replace the battery.
Decrease in battery life
Reason: Battery aging, improper use of the battery, and irregular charging.
Solution: If the battery is aging, you may need to replace a new battery. Avoid over-discharge and over-charging during use, and try to charge when the remaining power is about 20%. Maintain a regular charging habit to avoid not charging for a long time.
2. Motor failure
The motor does not rotate
Reason: Motor circuit fault, controller damage, motor fault.
Solution: Check whether the motor circuit is loose, short-circuited or open-circuited, and repair it if necessary. If the line is normal, there may be a problem with the controller, and the controller needs to be checked and repaired or replaced. If the controller is normal, the motor itself is likely to be faulty, and professional maintenance personnel are required to inspect or replace the motor.
Insufficient motor power
Reason: Insufficient battery power, internal wear of the motor, transmission system failure.
Solution: Make sure the battery power is sufficient, and charge it in time if the power is insufficient. If the battery is normal, it may be internal wear of the motor, and professional personnel are required to inspect and repair it. Check the transmission system, such as belts, chains, etc., for looseness or damage, and adjust or replace them if there are any problems.
3. Brake failure
Brake failure
Reason: The brake line is loose or broken, the brake block is severely worn, and the brake system fails.
Solution: Check whether the brake line is loose or broken, and tighten or replace it if necessary. If the brake line is normal, check whether the brake block is severely worn. If it is severely worn, replace the brake block in time. If none of the above methods can solve the problem, it may be that the brake system is faulty and needs to be inspected by professionals.
In short, when using a lead-acid scooter, pay attention to correct use and maintenance, and promptly discover and solve faults to ensure the safety and normal use of the scooter.
