Charging Laptop in Car Battery Life
As the weather gets colder, many of us find ourselves spending more time in the car. And if you’re like most people, you probably take your laptop with you to stay productive while on the go. But did you know that charging your laptop from your car battery can actually shorten its lifespan?
Here’s why: When you charge your laptop from a car battery, the battery goes through what’s called a discharge-charge cycle. This means that it first has to discharge some of its power to charge your laptop, and then recharge itself afterward. The problem is that this process puts a lot of strain on the battery, and over time, it will start to degrade.
So how can you avoid this? Well, there are a few things you can do. First, make sure that you only charge your laptop when absolutely necessary.
If possible, try to use an AC adapter instead (this will also help prolong the life of your car battery). And second, if you must charge from the car battery, make sure to disconnect as soon as your laptop is finished charging. This way, the battery won’t have to go through another discharge-charge cycle until it’s absolutely necessary.
By following these simple tips, you can help extend the lifespan of both your laptop and car batteries!
Charge the Car Battery With Laptop Charger
