Charging your car’s battery can be a hassle, but there are ways to make it easier. In this article, we’ll tell you how long you should leave your car running to charge its battery.
How long to leave a car running to charge battery
Running your car’s engine to charge its battery can be a quick and convenient way to top off the battery’s power. However, you shouldn’t leave your car idle for hours at a time if you want the battery to last as long as possible. A few minutes of running time each day is usually enough to keep your battery in good shape.
If you’re using a standard 12-volt battery, running the engine will drain it by around 3 percent per hour. So if your car has a 6-volt battery, leaving it running for four hours will actually result in a decrease of 3.6 percent in the battery’s charge. That said, there are some exceptions to this rule. If your car has an auxiliary power outlet, for example, you can leave it plugged in and charging while you do other things.
Battery types
Electric vehicles have come a long way since their inception. Not only do they offer an environmentally friendly option, but they are also incredibly affordable to operate. However, one downside to electric vehicles is that their batteries can only be charged with electricity. This means that if you are travelling in an area without access to an electrical outlet, your battery will not be able to recharge. In this article, we will discuss the different types of batteries and how long they take to recharge.
The traditional battery used in cars is a lithium ion battery. This type of battery is relatively slow to charge, taking around eight hours to reach a full charge. Lithium ion batteries are also more expensive than other types of batteries, so it is important to choose the right one for your vehicle. For example, a small electric car like the Tesla Model 3 requires a smaller lithium ion battery than a large SUV like the Ford Expedition.
Another type of battery used in electric vehicles is the nickel-cadmium battery. These batteries are faster to charge than lithium ion batteries, but they also suffer from shorter lifespan and require more care when handling. They are most commonly found in small electric cars and motorcycles.

How long it takes to charge a battery
How long it takes to charge a battery depends on the type of charger, the battery’s state of charge (SOC), and ambient temperatures. A full recharge for a lead-acid battery typically takes 6 hours at a slow rate or 12 hours at a fast rate. A lithium ion battery, which is the type most commonly used in vehicles, typically takes about 3 hours to reach 50% charge from a full discharge.
What to do if you forget to turn off the car
If you forget to turn off your car, you may be able to leave it running to charge the battery. The key is to stay aware of how much battery power is remaining so that you don’t overcharge the battery and cause it to fail prematurely.
The amount of time it takes for a car battery to charge depends on the type of battery, how deeply the battery is discharged, and the climate conditions. In general, though, a standard 12 volt car battery will take about two hours to charge from 0% to 100%.
Conclusion
It can be tough to know how long to leave your car running to charge the battery, especially if you’re not familiar with the different types of batteries. To help make things a little easier, we’ve put together this guide that outlines the basics of all three types of batteries and their respective charging times. So whether you’re looking for a general guideline or want to find out exactly how long it takes to charge your specific battery type, we’ve got you covered!
