What are the main technical requirements for sealed lead-acid batteries for electric bicycles?

The technical requirements for sealed lead-acid batteries for electric bicycles are specified in accordance with the "General Technical Requirements for Electric Bicycles".
1. The capacity of the electric bicycle battery
The current electric bicycle motor is 36V180W. The battery capacity is specified as 10Ah (ampere hour) and 2HR (hour rate). It can reach 2 hours with 5A discharge.
The meaning is: the electric bicycle is discharged at 5A and can be used for 2 hours, the driving speed is 20km, and the driving speed is 40km. When the battery capacity drops to 70%, the discharge time is 1.4 hours and the mileage is 28KM. It meets the requirement that the mileage of the battery is greater than 25km on a single charge.
When the driving current is greater than 5A, the driving is less than 40KM; when it is less than 5A, it can exceed 40KM.
2. According to the technical conditions of battery capacity and life, it can be described as: electric bicycle, under standard conditions, the average working current should not be greater than 5A. When the battery is new, it can travel 40KM, and the battery can travel 28KM at the end of its life. It takes more than one year for the mileage of an electric bicycle to drop from 40KM to 28KM.
