All rechargeable batteries wear out over time and their performance degrades. The average user will notice a significant reduction in run time after 18-24 months. Users who consume a lot of power will usually experience reduced run time before 18 months.

What can I do to make my battery last longer?

1. Choose the right battery. Under the same usage conditions, a low-capacity battery will wear out faster than a high-capacity battery because it needs to be charged more frequently.

2. Use your laptop's power saving controls to reduce daily battery usage. For example, turn off Bluetooth when not needed and lower the screen brightness when conditions permit.

3. Avoid exposure to extreme temperatures. If the system is exposed to extremely cold or hot temperatures, warm it up/cool it down before charging.

4. Contrary to previous batteries, modern lithium-ion batteries do not need to be fully discharged to remain in good operating condition.

5. All batteries wear out over time and with use. When you find that the runtime is no longer satisfactory, you may need to purchase a new battery.

How do I know when the battery needs to be replaced?

I decide whether I need to replace the Dell laptop battery based on its status ? Generally speaking, we check the battery information of our laptop and we can get a general idea of the battery status through this information.

Check the battery information on the computer BIOS information interface

Take Dell laptops as an example. Press the power button of the laptop. When the Dell logo appears on the screen, continuously tap the "F2" (or Fn+F2) key on the keyboard to enter the computer BIOS interface.

In the Settings menu, expand the General option and select Battery Information. In this way, you can view the battery power level, health status, whether the adapter is connected, and other information on the right side of the interface.

On the right side of the battery, there is a percentage value display, which shows the battery power percentage, which is the same as the value we see on the battery icon in the lower right corner of the operating system.

However, it should be noted that this value refers to the ratio of power to existing capacity, not the ratio of power to designed capacity. After the battery has been used for a long time, the actual capacity will be much lower than the designed capacity!

In the BIOS interface, we can easily view the battery's "Health" information, which reflects the actual status of the battery:

Excellent——I am in excellent condition, like a vigorous horse, ready to meet challenges at any time

Good——My capacity has decreased, but it does not affect my ability to continue to provide you with power

Fair - My energy has been greatly reduced, maybe it's time to give me a break

Poor——I may be saying goodbye to this world soon, and every charge may be my last

This health information is like a self-test, allowing us to better understand the condition of the battery and judge whether the battery needs to be replaced.

How to choose a battery

After confirming that the battery needs to be replaced, we need to check the battery model and specifications as well as the warranty period. When the laptop is out of warranty, the cost of replacing the original battery at the official after-sales service center is generally not cheap, and the user needs to bear the battery cost and the maintenance personnel's labor cost.

Therefore, it is obviously more cost-effective to purchase a battery that is compatible with the laptop on an e-commerce platform and replace the battery yourself.

It should be noted that the specifications of lithium batteries built into laptops of different brands and models are not uniform. In addition to the battery capacity (measured in Wh), the battery shape, thickness, and operating voltage/current also vary.

Considering that the quality of lithium batteries will directly determine their cycle life and safety, when choosing a laptop battery, do not blindly trust the quality of the original laptop battery, but should judge the quality from the material and craftsmanship of the battery.

In addition, pay close attention to what kind of warranty the manufacturer provides for the battery. The battery has the shortest warranty period among all laptop accessories. Most are only warrantied for 3 months to 6 months, and some are not even warrantied at all. There are very few batteries with a warranty period of up to one year.

Therefore, consumers must ask clearly about the warranty period and conditions of the battery before purchasing a laptop.

So when buying a second backup battery for your laptop, you should pay attention to the following points.

High-quality batteries require strict control in material selection. High-quality materials are the basis for ensuring high-quality batteries.

Laptop batteries are mainly composed of COB boards, battery packs, protective materials, shells and other components, and the quality requirements for all components are very high. When purchasing, you cannot open the battery to identify the material of the product, so how do you choose it?

Safety

A high-quality battery that has undergone strict process control must have passed the national and international certifications commonly required for electronic products, such as 3C, CE, UL, ROHS, etc. These are the prerequisites for ensuring that product quality meets standards.

Exterior

High-quality batteries produced by regular manufacturers also have high requirements for packaging. Consumers can judge from details such as the feel of the product packaging, the clarity of the handwriting, the location of the label, etc.

The paper of high-quality battery packaging produced by regular manufacturers is delicate and has a good texture. The handwriting printed on the packaging is clear and legible, without any mistakes, missing words or ghosting.

After-sales

Most computer batteries have a one-year after-sales warranty, and some brands even offer a two-year free replacement battery service. This move not only demonstrates the brand's confidence in product quality, but also provides more protection for consumers.

Although the battery itself is not easy to damage, some minor problems may occur during installation or use. For example, after a few days of use, the battery life is significantly reduced, and then the battery needs to be replaced in time.

With the support of after-sales service, consumers can choose to use these battery products with quality assurance with more confidence.
