If you are not sure how to charge a battery for a car? Wondering how long it takes for a car battery to charge? Or don't you know that a car battery has to be removed to charge it? So you are in the place, as this guide helps get all the answers related to the car battery.

Car batteries, for a variety of reasons, will go flat. If you forgot to switch off your lights when you park your car or parked your car for a long period, you might come back to find that there is not enough charge left for the battery to start the car.

And if you jump start as a quick fix, to keep it in good condition, it's a good idea to look at adequately charging a car battery. Find out how below.

Can you charge a battery in the car?

Yes, you can charge the battery when it's still inside the car or if it's removed; either method is good. Let's see how to charge a car battery that's connected to the car with a Charger:

  • Clean the battery terminals of any debris with a damp cloth or a wire brush.

  • With the UNPLUGGED battery charger (assuming it is a smart charger), link the red cable to the car battery's positive terminal.

  • Then join the black cable to the negative terminal of the vehicle battery.

  • Now insert your charger into the wall or the extension cord that is plugged into the wall.

  • Unplug the charger when the charging phase is complete.

  • Wait for ten seconds for any residual power to dissipate, and first cut the black cord.

  • Remove the red wire.

In around 10-11 hours, a 5-amp charger can charge a car battery, and 2-amp maintainers require 1-2 days depending upon the battery capacity.

Can a completely dead car battery be recharged?

It is stressful to recharge a dead car battery after turning the key in your car and not even hearing a sound from the starter, but don't panic, because you have options. In fact, there are several options to deal with bringing juice back into your car battery, but with every situation, not all are suitable.

Check out these recharging ideas that will prevent any damage to both your batteries and your vehicle.

First, how dead is the battery?

It is really useful to know exactly how dead it is when you recharge a dead car battery before considering how you're going to deal with it. When tested with a voltmeter, a long-lasting battery would display 12.4 to 12.7 volts at all terminals, a basic gadget that is very useful when diagnosing battery problems.

If the voltmeter shows lower than 12.4 volts, you will run into problems as you try to start your engine.  How much lower will determine what system you can use to charge the battery after you jump-start the car and get it to run again.

Above 12 Volts- Go For A Drive

In general, it is safe to charge it using the alternator in your car when the battery exhibits between 12 and 12.4 volts. This means driving the lowest possible electric distraction – no stereo, no lighting (do not test this at night), no heating or cooling functions – to ensure that the alternator sends as much energy as possible into the battery. Often, you want to keep the car or truck as much as possible idle as higher revolutions are going to give the charging device more power. The battery is recharged to a stable level for your next start after 30 minutes of drive.

Below 12 Volts, use a dedicated charger.

Your vehicle's alternator can hold a healthy battery charged, but it has never been designed to fully recharge a dead car battery if it is less than 12 volts. Using an alternator to deal with such an exhausted battery will potentially damage your alternator because it needs to work more to fill the battery while still dealing with the car's energy needs while the vehicle is working. It can also damage the battery by undercharging it in this way, making it less able to hold the charge the alternator placed on it.

The safest thing to do with a severely drained battery, either before or directly after a jump-start, is to attach it to a dedicated battery charger. These charging devices are designed to supply electricity to a dead battery at the rate required to charge it safely and deeply without causing any harm. Most of the time, you can also attach the battery to one of these chargers without having to remove it from your car.

Don’t take chances with your battery. Using the right charging technique will prolong your battery life and make sure you don't get stuck again.

Do you require to disconnect a car battery to charge it?

It'd be a smart idea to hook it up to a charger if you ever had a low battery or a battery you had no driving plans for a while. After you have popped the hood, you might wonder if the charger can just be hooked up to the battery while charging?

Suppose you use a smart charger that has microprocessors to maintain the charge volume at safe levels. You do not require to detach your car batteries from your vehicle. It's best to detach your car battery if you have an old charger without a microprocessor.

Wondering why keep the battery connected with a smart charger? Without fear of frying your electronics, you can leave your car battery hooked to the car because modern smart charging devices are mainly mini-computers that carefully monitor the entire process of charging.

They emit the correct amount of current at each point of the charging phase to match up with the amount of current that your battery will absorb.

Wrapping it Up

Now you can keep your car battery in good condition and solve any issues that arise from the battery.  Hopefully, this article has enriched your knowledge, and you have got all the answers.
