All laptops run on batteries and every battery has a finite shelf-life. If your laptop battery charge is dwindling rapidly and you find yourself needing to plug it into a socket after just a few minutes, it's time to buy a replacement battery. After all, the whole point of a laptop is to have mobility and not be tied to a plug socket. If you're frequently on the road and rely on your laptop a lot, it's not a bad idea to have a second battery on standby as a spare.
The most important thing when shopping for a laptop battery is compatibility. Not all batteries are the same and you'll need to pick a battery that will fit and work in your specific laptop. There are several ways to identify the right battery. If you know the make and model of your laptop, you can often refer to the manufacturer's website to find a list of supported options and accessories, including batteries. You can also look at the battery currently installed in your laptop. There should be a label on it with the part number (an alphanumeric code) and a voltage. These two pieces of information together should be enough to identify the specific battery you need. If you're still struggling though, you can always contact our sales team for assistance.
