When the motorcycle battery is fully charged and filled with water, as long as the car starts every day, it can be used until the battery is scrapped. Because as long as the engine starts, the battery is being charged.
If the battery runs out of power, models equipped with a separate ignition circuit can start driving by pedals and other means.
Models with DC ignition system cannot be started. But as long as the power is enough to start, you can drive. Because the power of the DC igniter should be taken from the battery. As soon as it is started, the electricity from the engine is supplied to the DC igniter.
The battery has a battery with water and a battery without water: you only need to check whether the water level of the battery drops below the minimum mark every 3 months. There are generally 2 marks on the upper end of the battery. The upper line is the upper limit line. When adding supplemental liquid, the highest line cannot exceed this line, the lower line is the lower limit line, and the lowest cannot be lower than this line.
