How Long To Charge A Car Battery At 2 Amps Well Fixed Weblogs Picture A dead car battery takes anywhere between 4 to 24 hours to be charged fully. the time varies according to the amperage and size of the battery. usually, a common rate for car battery chargers is a 4 amp one, and a dead 52ah battery will need at least 10 hours to charge fully. however, after one hour of charging the car will be able to start. A completely discharged car battery can take up to twelve hours to recharge, sometimes longer, depending on the type of battery you have. nobody wants to jump into their car, and upon trying to start the ignition, you get no response from the engine. the good news is that if it's a dead car battery, there are several options to charge it up again.

(which is probably why your car wouldn’t start.) it can take about eight hours of highway driving to charge a car battery to almost full. eight hours at 65 mph is 520 miles. Connect one end of the negative jumper cable to the negative terminal on the charged battery and the other end of the cable to a grounded metal component on the car with the dead battery, like the frame or chassis. turn on the car with the charged battery. leave the cars connected for at least five minutes. You can do this by applying an overcharge to a fully charged battery using a regulated current of around 200ma (milliamps) for a period of roughly 24 hours. this allows the battery's terminal voltage to rise between 2.50 and 2.66 volts per cell, which helps to dissolve sulfate crystals. if your battery is discharged too low to attempt this. Above 12 volts — go for a drive. in general, if the battery is showing between 12 and 12.4 volts, it’s safe to recharge it by using your vehicle’s alternator. this means driving around with as low of an electrical draw as possible — with no stereo system, no lights (don’t try this at night) and no heating or cooling functions running.
