the ideal current or amps to charge a car battery are 20% of its full capacity e.g 10 amps for a 50Ah battery the ideal charging current for a 12v 7ah battery is 1.4 amps maximum charging current for 100Ah battery should not be above its 20% of full capacity (20 amps)
Charging a car battery typically uses around 12 to 16 kilowatt-hours (kWh) of electricity, depending on the battery’s capacity and the charging method used. Is it cheaper to charge a car battery at home or at a public charging station?
For instance, charging an electric car with a 100 kWh battery pack would consume around 35 kWh of electricity per 100 miles of range; while charging a traditional car battery that is typically rated at 12-volts and consumes about 500-1000 watts, a lower amount of electricity is required.
Fast charging electric vehicles, on the other hand, can use a lot more electricity, sometimes up to 150 kW or more per hour. Overall, charging a car battery isn’t as energy-intensive as some other activities, but it still consumes a significant amount of electricity, especially if it’s done frequently.
In essence, charging a car battery requires an electrical current that varies depending on the battery type, capacity, and the charger used.
On average, it takes about 20-50 Amp-Hours to charge a car battery, which translates to around 250-500 watts per hour. However, charging a battery using a dedicated charger that handles the process more efficiently consumes less electricity than charging from the alternator while the engine is running.
