How Long Does A Car Battery Charger Take To Charge. It is best to slow charge the battery. Its a simple calculation.
The charging time heavily depends on the car battery and the chargers power output. These factors majorly determine how long it takes to charge the battery of any car. How long the charger will take depends on the amperage of the battery charger.
Most drivers top up charge rather than waiting for their battery to recharge from empty-to-full.
Generally the time taken to charge a battery from flat to full is determined by the amperage. Of course you dont have to get the battery to full charge to get it to start the car. As you know 2 amps battery charger can charge 2 amps battery in one hour it will take 24 hours to charge a 48 amps car battery. Charging a car battery fully with a 12 volt charger will take around 12 to 24 hours depending on the situation.
