How long does the car generator recharge the battery? Strictly speaking,
Depending on the power of the car generator, the power is large and the charging is fast, and the charging is slow.
Depends on the output current, high speed when the current is large, short charging time. Low speed of the current small charging time.
To see how much is left before the battery is originally uncharged, the remaining much of course charging fast.
④ How much battery capacity, is 40, 60 or 100 or 200Ah battery, you did not say. The higher the storage capacity, the longer the charging time. Otherwise, the time is short. To give you a reference, take 100Ah battery as an example, when the storage power is 0, charge for about 10 hours with 10A charging current. However, in practice, for the sake of battery protection and safety, it is usually charged at a current of less than 5A for 20 or more hours. In particular, the new battery needs less current to charge! Remember: do not overcharge remember not to charge with large current, so as to avoid dangerous accidents
A dead car battery can be fully charged in about four hours. The generator on the car needs a speed of more than 2000 RPM to reach full load operation, and the power generation at this time reaches the standard value on the nameplate. However, it is generally not recommended to use the car's generator to charge a non-powered battery.
