How Many Amps is a Motorcycle Battery?

[VonGianna]

Motorcycle batteries are generally 2.5A, 4A, 5A, 7A, or 9A. 2.5A and 4A are not commonly used. 5A is typically used for 90cc, 100cc, and 110cc engines, costing around 70 yuan. 7A and 9A are generally used for engines above 125cc. Avoid storing the battery in a discharged state: A discharged state refers to when the battery is not recharged promptly after use. In this state, sulfation is likely to occur, where lead sulfate crystals form on the plates, blocking ion channels and leading to insufficient charging and reduced battery capacity. The longer the battery remains idle in a discharged state, the more severe the damage becomes. When the battery is not in use, it should be charged once a month to extend its lifespan. Regular inspection is essential: During use, if the range of an electric bicycle suddenly drops by more than ten kilometers in a short period, it is highly likely that at least one battery in the group has issues such as broken cells, softened plates, or shedding of active material from the plates, leading to a short circuit. In such cases, it is important to promptly visit a professional battery repair facility for inspection, repair, or replacement.
