Generally speaking, traction, 20A discharge for 5 hours.
The starting type and the fixed type 5A are discharged for 20 hours.
In principle, the greater the current, the shorter the discharge time, and the smaller the current, the longer the discharge time.
If it is fully charged and discharged every time, the life of traction type is about 300-500 cycles, and that of starting type is about 80 cycles.
