The charging time for electric bicycle batteries is usually between 6-8 hours. The specific time depends on the battery type and charging method:
Lead acid batteries: Charging time is relatively long, usually taking 6-8 hours. In summer, the charging time can be shortened to 6-8 hours, while in winter it needs to be extended to 8-10 hours.
Lithium batteries: Charging time is relatively short, taking about 4-6 hours. The charging time in summer can be controlled within 4-6 hours, while it is recommended not to exceed 8 hours in winter.
