How to Charge Laptop Battery Without the Laptop

If you’ve ever found yourself in a situation where you need to charge your laptop battery, but the laptop charger isn’t with you. Or maybe you do have the laptop charger but for some reason the battery won’t charge. This can be an anxiety ridden experience. There are many reasons why a laptop battery fails to charge. But if you can rule out the charger, port and battery as the culprit. Then, here’s a quick guide on how to charge laptop battery without the laptop. Just remember that this only works with laptops that have detachable batteries.

Let’s dive in!

Method 1: Try Charging Your Battery Externally

A few laptop battery models are compatible with external laptop chargers. If your battery falls under this category, it’s likely time to pick one up that works with your laptop’s adapter and battery.

But what should you consider before buying one?

Not all laptop battery adapter cables are designed the same way. So, when shopping for an external battery charger, you’ll want to ensure that your adapter cable is a complimentary match to plug into the external battery charger.

In like manner, not all laptop manufacturers design their batteries the same way. You’ll want to make sure to get an external battery charger with the correct amps and voltage for the battery in your laptop.

Your laptop’s user manual tells you everything you need to know about your laptop model. If you can’t find this information there, you can check the bottom plate cover for your laptop’s details or get the information from the Control Panel.

Just launch the Control Panel from the Start menu, then go to System and Security. This will take you to the System Information panel, where you’ll find data regarding your laptop’s model.

After taking note of these specifications, visit the website of the seller that you wish to buy the external battery charger from. Choose your favorite product while making sure it’s compatible with the specs of your laptop.

Method 2: Use Another Laptop to Charge Your Battery

If you can’t charge the battery through your own laptop and aren’t able to connect it to a suitable external charger and you now find yourself totally out of options. It’s time to think outside the box; this will be a worthwhile last resort.

In this method, you’ll need to detach the battery from your laptop and fix it into another laptop of the same model and specification. Of course, what makes this method highly challenging is because the odds are slim to none of being able to find a laptop that’s identical to yours when you need it most.

Still, it’s an option worth considering if your ever find yourself in this situation.

Can I Charge a Laptop Battery Without the Laptop If the Battery is Non-Removable?

Most laptops now come with undetachable batteries which makes them far lighter than laptops with removable batteries. Unfortunately, you won’t be able to charge an internal battery outside your laptop if you’re not an experienced technician.

It’s not advisable to remove or tinker with an internal battery since it can be risky. If you ever want to fix an undetachable battery, it’s best to take your laptop to an expert. They’ll have all the right tools, instruments (and know how) to get the work done and fix your problem.

Even if you do know how to remove a laptop battery and recharge it with a dedicated external charger. The process may not be so simple. Plus, acquiring the tools needed to do this properly might end up costing you a small fortune unless you’re already privy to them. In that case, it might be more cost effective to just buy a new battery or a budget laptop.

How Else Can I Charge a Laptop Battery Without Its Charger?

In many cases, you might find yourself stuck with a malfunctioning charger without the option of simply buying a new one. In this section, we’ll go through a few techniques you could use to recharge your battery without the laptop charger.

Bear in mind that many laptop batteries only work with their original chargers. Therefore, you may need to try a combination of the following methods until you find the solution that works best for you.

You also needed to prepare yourself for the distinct and very real possibility that none of these solutions will work for your situation – You may end up having to buy a new charger or battery in the long run. Plus, you may not be able to charge built-in laptop batteries manually.

While this may not be the answer you wanted to hear, let’s take a look at a few possible solutions to get your laptop battery working again.

Solution 1: Try Using a Universal Power Adaptor

One of the best and most affordable ways that you can manually recharge your battery is by using a universal power adaptor. They’re widely available in online and offline stores, so it’s easy to find.

Plus, it could be useful if you’re traveling, and your charger isn’t compatible with the voltage system of the country you’re in. A universal power adaptor will match the voltage to your battery’s requirements.

Still, before you purchase the adaptor, make sure that it supports the model of your battery. Using an adaptor that isn’t 100% compatible with the battery could damage it, which is not ideal.

Solution 2: Consider Investing in a Laptop Power Bank

This is another good solution to have as a backup if you think you’ll need to charge your battery without the charger at any point. Laptop power banks are lightweight and travel-friendly, just what you need for taking it along with your laptop.

Make sure that the power bank you select has the right output port so you can easily connect it to your battery. In addition to that, the power bank needs to be compatible with your DC adapter.

Luckily, many power bank models come with multi-DC adapter support, which is a relief. As long as you ensure that the specs of the device you’re buying work seamlessly with your laptop battery, you’ll be good to go.

Solution 3: Give USB-C a Shot

For this solution to work, the laptop must have a built-in USB-C port. The good news is that most laptops these days have this feature, so you’ll probably have nothing to worry about. Older laptop versions may lack a USB-C port, though.

To recharge your laptop using a USB-C cable, simply plug one end of the cable into the laptop and the other end into a power outlet. The cable will act as an alternative to an AC/DC adapter.

Solution 4: Use the Help of an AC Adapter

Most of the time, your charger won’t work because the adapter end has become faulty. The damaged adapter will prevent the flow of electricity, which will keep your battery from charging normally.

Therefore, a good place to start is by only replacing the AC adapter. Usually, it’s easy to tell if the original adapter is faulty by looking at the LED light indicator on it. If it remains off after plugging the charger into a power outlet, then you may need to buy a new AC adapter.

Solution 5: Go for a Portable Laptop Charger

A portable charger can be useful if say you’re travelling to a foreign country and your charger’s plug won’t go into the outlet of the country you’re visiting. Another thing to keep in mind is that the voltage or current might be different from what you need.

In this case, if your laptop charger isn’t compatible with the country’s voltage system, you’re better off trying other alternatives to recharge it.

Solution 6: Get a New Battery

Sometimes it’s just inevitable that you’ll have to get a new battery if all else fails. It could just be that the life cycle of a laptop battery is simply over, and it’s finally time to invest in a new one. But how can you tell if this is the case?

Just find another laptop of the same model as yours and replace its battery with the one from your laptop. Then, try to charge it using the other laptop’s charger and check the charging status.

If the battery still can’t charge, that’s a clear sign that it needs to be replaced.

How Do I Charge My Laptop Battery Correctly?

Learning the right way to charge your laptop battery will help increase its lifespan. Here are a few useful tips to help you achieve this goal.

Don’t Drain Your Battery Before Charging

This is a common mistake that we’re all prone to making at some point. It could be that you’re deeply focused on a particular task or so immersed in a movie you’re watching on your laptop that you don’t even notice the battery slowly ebbing away. Unfortunately, this can shorten the life of your battery.

Instead, by ensuring that your laptop is always within a 40% to 80% charging status. The performance of the battery will always be top-notch.

In addition, you’ll want to make sure you never leave your laptop in direct sunlight. Not only can leaving it in open sunlight have a negative effect on the battery but doing so might also harm other parts of the laptop.

Don’t Leave the Charger on for Too Long

Heat could do damage to your battery and minimize its lifespan. A laptop battery can easily become overheated if you leave it to charge for too long, especially if it’s an older model.

Newer models will automatically stop charging once the battery is 100% charged. Still, it’s better to unplug the charger once the battery is full.

Avoid Mixing Up Wires

Another thing that can harm your battery and motherboard is not using the adapters provided by the manufacturer. If you must use another adapter, make sure it matches the specs of your battery perfectly.

This will go a long way to prolong the lifespan of your laptop battery.

In Summary

As we said, there are many reasons why a laptop battery may fail to charge. External chargers, super batteries, AC power adapters are some of the best ways we’ve found to bring life back to a laptop battery manually. Also maintaining the battery’s health will also keep it functioning as it should for the lifespan of the laptop Although it’s no fun to have a bricked laptop, hopefully one of these methods and solutions can get you on your way again.
