- If the battery is fully discharged then the first approximation for the charge time is (50 Amps*Hours) divided by (10 Amps) = 5 Hours. Truthfully, this is a rough estimate and it usually tells us how long it will take to recharge the battery to about 80% of its capacity.ither the battery charge current will drop to less than 0.1 amp (from an initial value of 1.25 amps) or, if the current does not drop below 0.1 amp, then the charger will hold the battery voltage at 14.5 volts for 6 to 8 hours. There are a couple of reasons why the battery current may not drop below 0.1 amp.

However, if the car has an alternator, disconnect the battery. beforehand: otherwise some alternators-generally the older type-can be damaged. If separate. caps are fitted, remove them for ventilation.

Determining Charge Time Therefore it is necessary to put about 30 amp hours plus 20% more to compensate for the internal resistance in the battery for a total of 30 amps x 0.2 = 36 amp-hours to fully charge your battery. Step 3: If you charge your battery at a 10-amp rate and you need to replace 36 amp-hours in the battery. To determine how long (in hours) you will need to charge your battery, divided 36 by 10 = 3.6 or 3.6 hours to recharge your battery. A 12 volt / 10 amp 3-stage automatic charger is the best charger for most automotive batteries.

- Fast charge: Repeated fast charges on a battery may overcharge a battery and reduce service life. Step 1: Determine how long to recharge a battery by calculating how much capacity your battery has. For example, an Interstate battery with the part number MT-34 has 120 minutes reserve capacity.tep 3: Charge the battery at a 10-amp rate. 42 amp-hours needed by the battery divided by 10 amp charge = it will take around 4-1/2 hours to recharge the battery.

Determining Charge Time If a battery is very discharged then it can take up to 12 hours or more to recharge it. While recharging a battery, if the battery becomes hot when you touch it then stop charging it. Slow charge: It is best to slow charge the battery.Slow charging rates vary depending on the battery's type and capacity.tep 3: Charge the battery at a 10-amp rate. 42 amp-hours needed by the battery divided by 10 amp charge = it will take around 4-1/2 hours to recharge the battery.

An average car battery has a capacity of around 48 amp hours which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on. basic charger usually charges at around 2 amps-and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market-from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.

What are the causes for a car battery to totally discharge? If so, the alternator is good, and is pumping current into the battery using higher voltage. Let the car jump 5 minutes to charge the battery (the battery will reach full voltage in a few minutes if it is good, completely recharging it is another thing), and try to start it again. If it still won't start, the battery probably needs replacing, because it evidently won't hold a charge any more.

PowerStream car battery questions and answers A: Charging time depends on the battery and the charger. For a battery being charged by the car's alternator it can take an hour of driving to get it fully charged. Car batteries range from 40AH to 110AH, and alternators range from 45 amps to 200 amps. If you are using a battery charger, a 10 amp charger will take 4 to 11 hours to fully charge the battery, a 2 amp charger will take 2-4 days. Of course you don't have to get the battery to full charge to get it to start the car.

- So in this worst-case example it is going to take about 20x the amount of time spent cranking or about 10 minutes to replenish the battery. In more realistic scenarios the starting load will be much less as will the cranking time, and the energy used to start the car will be returned to the battery in a minute or two.

How Much Driving Will Recharge Drained Battery? Time for a new battery, or at least buy a plug in battery charger and follow the instructions on the charger, but I doubt if it will do any good. If your battery were still good it would take but a few minutes to charge enough for an immediate restart, and maybe 20 minutes or less for a full recharge.

- Mostly, @Anonymous got it right, but a few details. Idling a car for 5-10 minutes will not recharge a battery. It MIGHT replace a bit of the charge lost to starting it in the first place, but even that is iffy. The alternator in your car will need to hit, roughly, 2000 engine rpm to push a charge back to the battery.Keep the top of the battery clean, not just the posts.ostly, @Anonymous got it right, but a few details.
