There most certainly are times when you just find yourself in a pickle with a completely drained out battery and the laptop simply not charging it. In that case, learning how to charge a laptop battery without a laptop becomes essential.
There are basically two ways that you can accomplish this:
- Charging externally with an AC adapter
Using another laptop to charge the battery
Alternatively, if you are worried about power outages, then you can learn about ways to charge the laptop battery.
Ways to Charge a Laptop Battery Without a Laptop
1. Charging a Battery Externally
Some detachable laptops batteries come with the ability to hook up with an external laptop battery charger.
Before you decide to charge your laptop battery without having it attached to the laptop, you should ensure that it can interface with such adapters. You would have to ensure that the pins are compatible.
Laptop battery manufactures design batteries differently, and they may or may not be able to charge externally with such adapters.
This method only works with laptop batteries that are DETACHABLE. Internal laptop batteries work in a different manner. They do not have external chargers for them in the market.
Advantage of Externally Rechargeable Laptop Battery
This is a solution to those who would like to ensure that their laptop is always powered on despite having challenges of lack of laptop charger or electric power failure.
It is always advisable to get one or more extra laptop batteries to have in spare in times of need.
Having a battery that can be recharged without getting connected to the laptop is important in many ways. For example, if you are traveling and there is no way of charging your laptop, you could charge an extra battery while your battery is powering the laptop. Also, if your laptop charger is misplaced or fails, it may take a few days to purchase it.

Identifying Laptop Model
Before heading to vendor’s website, you should know your laptop information.
You could find it in the device manual that you were offered as you purchased the laptop. The laptop information can also be obtained in the control panel or below the bottom plate cover.
Identifying Model from System Information
You may or may not find the MODEL of your laptop in the system information. However you can still try by following the simple steps below.
- In Windows 7, you can easily access the system information by right-clicking on the Computer (This PC on Windows 10) at the start menu and then selecting Properties.
On the other hand, you can find the information from the control panel or using the system information tool.
- Power on the laptop and launch Control panel from the start menu.
- Click the graphics option titled System and Security. This will launch the System Information panel.
Having verified the information, you can now go to the vendor’s website and purchase a new battery or AC adapter connector that meets your specifications.

2. Using a Similar Laptop to charge the Battery
This could be the last resort in case you attempted the method above and it failed.
You actually need an extra working laptop whose model is similar to your current laptop. This method could not be the best option if you cannot acquire a similar laptop or when you are traveling.
In my opinion, the best way charge a laptop battery is by plugging an AC adapter to its connector. It would be advisable to have an extra battery so that while one is charging, the other one is powering the battery.

What About Non Removable Internal Batteries?
Most of the newer laptop models come with non removable internal batteries. Since these are slim and light, they have almost replaced the detachable laptop batteries.
If you happen to have one such laptop, then there is absolutely no way that you can charge this laptop battery without a laptop if you are not a technician.
You will either need a functioning laptop or require a lot of experience with opening up and fixing batteries. Only experienced technicians are advised to do this.
Plus if you go this route, the instruments and tools that you will need to open the battery, de-solder each and every battery and then recharge them with a dedicated charger would cost you almost as much as a budget laptop.
If you are an expert and you can remove the battery and at the same time create a contraption that has the same voltage and current rating as the battery, then you may essentially achieve the charging.
However, we highly advise against both removing the internal batteries without expert help as well as creating an external charging contraption. Playing around with the batteries is highly dangerous.

There are basically two ways to charge a laptop battery without a laptop in simple terms. Any other way would require you to open up the laptop battery, dismount each and every battery cell and charge them separately.
Since that is fairly complicated as well as a DANGEROUS method we do not recommend it. This is especially the case if you are not well versed with electronics.
Batteries are volatile objects. They come with several warnings. Therefore, tampering around with those without any prior knowledge is not recommended.
If all else fails, we would recommend that you visit an experienced technician.
