The Best Time To Charge A Car Battery: When Driving

by Phil Borges // in Car

Imagine that you are on a long road trip, and your car battery starts to die. How much time do you need for the battery to charge? How far do I need to drive before my car is charged again? How long does it take for a car battery to charge if driving? These are all important questions that many people have when starting their journeys. In this blog post, we will answer these questions and more so that you can be prepared for any scenario!

Most cars will charge a flat battery after thirty minutes driving at highway speeds. This is done by using the kinetic energy produced from rolling, which doesn't use any electricity used for lighting or adjusting temperature features in your car and potentially helps avoid risk of overcharging (which can be damaging to your vehicle). Let's take a look on how this works! How do you keep an empty battery charged? Drive it around! Most cars are capable of charging their batteries without being plugged into anything if driven enough times. To start with one should know that every time you drive, there is electrical power generated through the motion when accelerating but not braking - aka: Kinetic Energy Recovery System(KERS) . If these efforts aren’t sufficient then you can get your battery charged with a regular plug-in charger.

Battery Charging Quick Tips

It seems like the bane of existence is when a car’s battery dies and it always happens at the worst possible time. Here are some quick tips to get your vehicle going quickly without causing any harm, regardless if you have another good working vehicle or not!

If your battery is dead and you need to jump-start it, don't just connect the two batteries with a cable. First attach one end of each jumper wire to both car's terminals (red for positive/plus). Then put on gloves or protective gear before touching any metal parts that are exposed like screws, bolts etc. Start the donor vehicle in order to charge up its built-in alternator while running at 3000 rpm approx 5 minutes so as not have too much work load when starting out again after 10 mins..

Before jumping start your dying battery by connecting them together through cables, make sure they're connected properly first! Attach connectors from red terminal (+) wires; this will help power up flat batteries without overworking an already damaged battery and possibly causing a short circuit.

Charge Battery Driving

It's important to jump-start your car when you're stranded, but it can be dangerous if not done properly. First, turn off all electrical consumers on both cars and make sure they are turned completely off so the engine will not stall. Once this is completed, connect jumper cables in a specific order: red cable from positive post of one battery terminal to negative post of another; black cable from ground point (anything metal) at one end of other vehicle’s hood or frame directly over same type metal surface on first car’s hood/frame; then white neutral wire between opposite ends for each set up until fully connected with clamps tightly tightened down as well as any other clamps used to ground the connection. When you are leaving your car after a thirty-minute drive, it is important to know that if the battery or any other component in the engine has caused an issue with power-draining, then starting again may not be as simple. So make sure to park where there will be access for someone else around who can help start up your vehicle and avoid being stranded on those long drives home from work!

Risk To Battery Charging By Driving

You can charge your car battery with the engine turned off at home by plugging it into a standard outlet. The risk is minimal, but there are some risks to take note of depending on where you live and how much time you spend in traffic. Without panic or undue stress, remember that someone has been killed charging their flat battery this way before! Unless they have an emergency backup plan like jumper cables (which often work for both 12V cars as well) then I would highly recommend using a power-pack charger instead which plugs into any household socket just like electric toothbrush chargers do these days - apple watch style!. It's so quick and easy because all you need is one cable; no messing around finding places to hook things up.


Modern cars are almost like a small city on wheels. They have all sorts of electronics, which require power to operate and if the battery is not at full charge, certain features can fail temporarily. It's usually no big deal because your car has been programmed with safety measures so that when one part goes down it will only shut off non-critical systems such as radios or heated seats rather than hinder essential functions like steering wheel control or brakes; however, sometimes this problem requires you take a trip back to the dealership where they'll recalibrate sensors in order for everything else work again - even though it is just temporary!

Alternator workload

The alternator is a complicated piece of machinery. It can be slow to crank up, and it's not designed for charging batteries from flat. When you start your car with 12 volts in its system, electronics on the vehicle come online expecting their power supply straight away--at this point there should be enough juice left over that trickle down as needed and keep them charged all day long while other systems are running full steam ahead. But asking an alternator that's already been regularly doing more work than usual will significantly shorten its lifespan; ask one trying to top off drained battery throughout the day without any help when everyones else is going at 100% capacity might just spell disaster...

The machine known as the Alternator has gone through many evolutionary changes, but the basics of its design are tried and true. How long it will last varies from car to car, climate conditions, driving habits etc., but if you're lucky enough that your alternator goes out before needing a new battery, then there's some helpful information for you on how to replace an Alternator with minimal fuss.

Drive belt

Imagine you are driving on a hot day and your car battery suddenly dies. You have to drive the rest of the way home with no power steering, air conditioning or heat in order to charge it. This can be even more difficult when there is an incline because without being able to push down on the gas pedal, you will gradually lose speed as well as momentum while climbing up hills. Such conditions should not come into play if one has their belt replaced before they need any assistance from AAA (assistance for members only).

How to Check Your Battery Health?

  • Turn on your device and check the battery level.
  • Find out how many hours it can go before it needs to be charged again. Look at the charge of your phone as a measure of its health.
  • If you plan to store or travel with your device for an extended period, consider charging it to 100% and then turn off power saving features.

This way, if you find yourself without any electricity source, at least some full capacity will remain available in order to use all those important contacts stored on your phone and relay important messages upon return. The best option is always a safe backup that does not interfere with the device's natural function of storing energy as needed; which includes carrying around a portable charger with you.

How To Check Battery Voltage?

If you have a multimeter, use it to measure the battery voltage. If you don't have a multimeter, there's no easy way to check the voltage with just an analog testing device. You could try sticking two metal strips together, and then press one side of your fingertip on them. This will cause leucotrichia during low voltage readings. This is because potassium plays a huge role in nerve conduction and conduction velocity slows down during low power level reading (if you ever saw pictures or videos of someone electroshocking frogs). Once the voltage is picked up by the skin as we mentioned before, nerves firing away back into your finger will create that familiar pinching feeling which people often try to avoid.

How to fit a car battery?

First, check the owner's manual for your car because it will tell you how to install a battery. If you can't find that information, follow this link to install a car battery. The most important thing to remember when someone is helping you put in the new battery or taking out an old one is not to let them touch any of the connections on either side of the battery. To make things easier for yourself and whoever helped you, be sure your disconnects are loose before starting. Disconnects should be marked (B+). Make sure all cables are well clear from moving parts in engine compartment such as belts and pulleys so they don’t get caught and cause damage. Remove negative cable first from posts marked (-). Remove positive cable from posts marked (+), and then clamp off negative post. Put new battery in place, but don't tighten anything yet without first making sure it is seated well on both the battery tray and posts. Be careful not to over-tighten cables when installing the new battery or you could damage them. Tighten set screws if necessary.

How to notify a battery monitor?

Often computer systems will have the option to notify users when their battery is low on their screen. If a computer does not have this notification, or if the user would prefer warning with an external device, there are products that can track power consumption and warn at threshold levels. You can buy a battery monitor from your local electronics store, but we recommend using ConnectSense Smart Outlet 2 because it cuts down on power usage by turning off appliances plugged in to the outlet once they’ve fallen below 10%. Should you choose not to go through ConnectSense for some reason (either price-related or due to warranty concerns), BKON has other offerings available ranging anywhere between $32USD and $150USD.

How To Check Your Alternators Health?

There are a few ways to check your alternator's health. The first step is to inspect visually and see if the alternator is dirty, warped, torn or damaged in any way. If it is properly clean and not damaged, then you can look for external signs of damage such as pinched wires, loose connections, seized bearings or failed drive belts. One of the most common reasons for an alternator problem on modern cars where they usually seize up with age and become difficult to turn by hand when they fail. You can also measure the engine idle speed with a timing light while turning the engine using starter motor power only (not the ignition). A sluggish engine will have an erratic idle speed that will often exceed 600 rpm (+/- 200 rpm) and may be accompanied by a rough or choppy engine sound.

How To Check Your Alternator Voltage Output?

If you measure the voltage on the alternator's own power leads, you are reading battery voltage. The reason why is because there is a plug usually on top of the alternator that represents each stator output and these plugs are connected parallel to the main EFI harness within 4-8 inches. On most cars, there is one brown wire coming out from all of them and we label this as “BRN” for convenience purposes (since it comes out as BRN/B). A voltmeter probe can then be plugged onto BRN/B or any other stator tip but those would generally be more difficult to access since they're tucked in between rubber insulation and metal chassis parts. When using any other test jumper wires, make sure to put some insulating tape on the ends of them so they don't short out and cause any damage.

How To Volt Drop Test Your Alternator?

Answer: The most important way to test an alternator is with a voltmeter. No matter how you're going to test it, the first step is making sure that the battery and charging system aren't in need of repair! Some methods for voltage drop testing are:

- While standing next to the vehicle (ideal but not always possible), turn on your headlights and all fasteners/accessories. If your charging system checks out okay at this point, install a load tester on the battery terminals (there are various levels of loads from 50 amp to 250 amps) then run them at about 20% for any given length until your battery terminals fall below 10 volts (or enough wiggle room). At this point you could either remove the load and install the voltage dipstick to see how much juice is left in the battery, or turn off all interior lights and accessories for a few minutes.

- With a voltmeter connected directly to the alternator (or on one of your terminals), run it at about 20% for any given length until your battery terminals fall below 12 volts.

- With a voltmeter connected to the battery terminals, start your engine and drive for several minutes before stopping.
