The battery is the "mobile energy" of the laptop, and its importance is self-evident. Just like everything else in life, the laptop battery has a limited lifespan. No matter how carefully we maintain it, it will not last forever. .

How many times have you been in this situation? You're busy working on your laptop, maybe writing an important report or editing photos, and suddenly the computer reminds you that the battery is low. Unfortunately , I've been there too. In this situation, I knew that once the battery ran out, all my hard work would be gone, so I had to put down the work at hand and go find a power source.

This experience may be something that many people have encountered. However, when problems arise, many customers often don’t know where to start. Here are some quick problem-solving methods to help you quickly locate the root cause of the problem and find the most economical solution.

Here are the signs your laptop needs a new battery

The key to determining whether a battery needs to be replaced is to observe whether it is showing abnormal behavior. For example, if your laptop battery loses power significantly faster when performing simple tasks, this may be a sign of battery aging. Some customers who are not careful may not notice this subtle change, or even take it for granted, until they find that the laptop has only 2 hours of battery life left, then they realize that the battery has aged.

Another common sign is a battery that won’t charge. A customer may find that his laptop battery won’t charge to 100% even after charging overnight. A battery that once charged in an hour may now take 2 hours or more to charge. This isn’t a malfunction of the charger; it’s a sign that the battery is nearing the end of its life and may need to be replaced.

In addition to the trouble of battery charging, we also need to pay attention to the physical state of the battery. When you find that the battery is swollen or bulging, it means that a chemical reaction may have occurred inside the battery. Battery swelling will not only cause the notebook shell to deform, but may also affect the normal operation of other hardware. In this case, be sure to deal with it in time to avoid causing more serious damage.

In addition, the decline in laptop performance may also be a sign that there is something wrong with the battery. When you find that your laptop is running slower, even after closing all unnecessary programs, it is likely because the battery cannot provide enough power support. Some customers mentioned that this method can only alleviate the current problem to a certain extent, but cannot solve it fundamentally. In this case, it is very important to check and replace the battery in time to avoid affecting work efficiency.

Finally, if you notice a noticeable decrease in your laptop's battery life, even if you haven't done anything special, it may mean that the battery is due for replacement.

What should we do when a laptop battery fails?

Based on the previous article, we have identified the main causes of battery failure. After confirming the specific cause of battery failure, we can take some measures to restore the notebook's battery life to meet the needs of daily use.

For aging batteries, you can consider replacing them with new ones. There are various brands of laptop batteries on the market now, and you just need to find the one that matches your computer model. Generally speaking, the model information will be printed on the bottom of the computer or on the battery. You can also enter your computer model through search engines or e-commerce platforms to easily find a battery that matches it.

In daily use, it is recommended that users keep the battery power between 20% and 80% to avoid overcharging or over-discharging. Many users said that after following this advice, the life of their laptop batteries was significantly extended and the charging speed was faster. Of course, this method is not a panacea. It can only delay battery aging, but cannot completely prevent battery aging.

When using a laptop, try to avoid placing the device in a high or low temperature environment. In summer, the temperature is high, and the laptop will heat up if used for a long time, resulting in performance degradation, and even freezing, blue screen and other problems. In winter, the temperature is low, and the laptop is used in a low temperature environment, the battery life will be shortened, and it may even fail to start.

If your battery has a hardware failure, the situation may not be optimistic. In this case, you cannot solve it yourself and need to seek help from professionals. Professional repair personnel have professional knowledge and skills to diagnose the cause of the battery failure. If the battery cannot be repaired, they will recommend that you replace it with a new one.

The health of your battery is related to the normal use of your device. Do not ignore any fault signals.
