The lead-acid battery capacity has several marking methods?

At present, the lead-acid battery capacity has several indication methods, such as C20, C10, C5, C3, C2, respectively, showing the actual capacity of discharge rate at 20 h, 10h, 5h, 2h, respectively. If it is a capacity at a 20H discharge rate, it is indicated that the battery of C20, C20 = 10ah, which means the capacity value obtained at C20 / 20 current discharge 20h. Convert C5, that is, 4-fold discharge of the current specified by C20, the capacity is only about 7ah, and the electric bicycle is traveling in the 1 to 2h, and the lead-acid battery is 1 ~ 2h (C1 to C2). It is close to 10 times that of the specified current, then its actually supplied electric energy is only 50% to 54% of C20 discharge capacity. The battery capacity is labeled C2, that is, the capacity indicated by the rate of 2H discharges, if not C2, the calculation should be calculated to derive the correct discharge time and capacity. If the capacity indicated by the 5H discharge rate (C5) is 100%, if the actual capacity is only 88%; the internal volume is completed, only 78%; 1h is completed, only 5h is discharged 65% of time capacity. The labeling capacity is assumed to be 10ah. Then it can only get the actual power of 8.8AH with 3H discharge; if it is discharged at 1H, only 6.5ah power is obtained, and the discharge rate can be reduced, and the discharge current is> 0.5c2 not only the capacity is reduced, but the life of the battery There is also a certain impact. In the same way, the battery is indicated (rated) capacity of C3, the discharge current is C3 / 3, ie ≈0.333c3, if it is C5, the discharge current should be 0.2c5, the class push. The lead-acid battery current C20 is generally used in automobiles, ships, diesel engine groups, C10 for UPS, photovoltaic storage, solar energy, C5 is a lead-acid battery for traction, can be used in electric forklifts, tricycles, etc. The vehicle, C3, C2 are generally a valve-free maintenance-free power battery, suitable for sightseeing vehicles, tour vehicles, patrol cars, two-wheeled electric vehicles and other scenes, and the capacity embodied in different labels is inconsistent.
