- I google, but found different kind of answers, some say 15 min, some say 1 min, some say it take days to fully charged.....i'm really confused...but two things i'm sure: #1 alternator will charge the battery, it mainly for supplying electricity to the car, not for charing, but it will charge the battery after a period of time.

How long and if a car battery would recharge? 20 minutes should be good if your battery is relativity new ,,meaning under a couple years. A car battery normally last 4-5yrs.. Cold weather has a big effect on how long a battery needs to be charge to get back to fully charged. If you live in a spot where it will be below freezing overnight.pdate: As stated, the battery and alternator are new. Very new. I do not have a battery charger, unfortunately. And it only drained because the car sat (turned off) for about 16 hours with the headlights turned on and no one knew it.

Beginner's Guide Charging times depend on the size of the car and how big the battery is. The typical charge time for pure-electric cars using a standard UK home wall socket is between six and eight hours. PHEVs and E-REVs take much less time to charge because they have smaller batteries. Most new pure EVs can also use rapid charging points that can top up the batteries to 80% capacity in around 30 minutes.

How Fast Can You Really Charge Your Plug-in Car? The Answer is More Complicated Than You Think In the US, your standard household outlet (Level 1 charging) can deliver about 1.6 kW (after accounting for losses and other items). To figure out how long it will take you to fully charge a given battery, simply divide the battery's size by the outlet's output. For instance, a 16 kWh battery will take 10 hours to fully charge from a standard outlet (16 kWh/1.6 kW).

- The lead acid battery uses the constant current constant voltage (CC/CV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries.

How can I charge a car battery at home? I've never measured this exactly, but in my experience, if you jump-start a car with a dead battery, 5 minutes of driving is probably enough for the car to start on its own, and 10 minutes is almost certainly enough.

- 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.

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.

How long does it take to recharge a car battery after starting? Assuming a typical lead-acid, 12 V car battery (typically at 13 V or so fully charged), and that it takes roughly 500 A over 3 seconds to start an engine, how long will it take to recharge the battery at any given charge rate? Over 3 seconds that's 19,200 joules.

- Now when you are driving in a city, the engine rpm will be minimum and will be near to idle rpm range. So it will take more than 30 minutes to 1 hr to reach fully charged condition from a typical worst case of 70% state of charge of battery. But in a high way drive cycle with high rpm ranges the alternator will generate high amperes and battery will be more than 95% with in 30 minutes.

How long does it take for car battery to charge? How long does it take for car battery to charge? Answer Wiki. Depends upon many things: depth of discharge, temperature, battery size & capacity, capacity of the charging device, and desired quality of charge. If the battery temperature is very low, it will not accept a charge until it has warmed up. At high temperatures, it accepts a charge extremely readily. If discharged fully, of very large capacity, and charged by a small trickle charger, it may take 24 hours to recharge.

How Long Does it Take To Charge an Electric Car? Let's take a few real-world examples: - The Nissan LEAF uses lithium-ion batteries, just like your laptop and your cell phone, but it uses a lot more of them. It can charge overnight (8 hours) at a 220/240-volt Nissan charging dock that's installed in your garage.

- The engine and charging system will work much better under load, while driving. Just idling the car for 20 minutes will not provide as good a charge as actually driving the car for 20 minutes. It will take about 20 minutes of driving to charge your battery. That is why short trips wear batteries out, they never get back up to full charge and the drain from starting the car doesn't get replaced.
