The service life of the laptop is long than ever, so the battery is an increasingly common problem due to aging and excessive use. So, what should I do? Lithium ion battery has amazing strength due to its size. They are strong enough, let our laptop run in a few hours, as the core of the latest smartphone, can even serve as a power plant behind Tip-seeking electric vehicles such as Tesla families.

However, the lithium-ion battery does have its limitations. Battery service is longer than ever, it is inevitable that the battery expansion occurs. You may have encountered this situation: you have stopped working using a laptop or mobile phone in many years, or may just start the signs of inside the body.

The mobile phone screen starts to convex, or the seam is opened, or the laptop keyboard protrudes. This may be due to the gradual or sudden appearance of a big bubble in the battery. But why can you do this? What can you do? We have talked with some engineers and experts from computer manufacturers and related companies to in-depth understanding of information about expanded batteries you need, and if you have battery how to use is the best way.

What causing the battery to expand? Battery expansion is the result of two things: energy density and heat. Expansion is due to excessive current flows inside the battery unit in a non-controlled manner results in heat and gas accumulation. This is because the material inside the battery is attenuated or subjected to pressure or physical damage over time.

A given laptop battery consists of multiple separate batteries, one or more of them may have problems. You will often see that the laptop battery is described as a four-core or six-core, indicating the internal structure of the battery. (Some laptops, usually business models, let you choose battery capacity / battery while purchasing, but this is less than in the past.

Notebooks rarely equipped with the fact that the battery is removed (in a sense, you can exchange and exchange them without opening the chassis) will exacerbate the problem. Arthurshi, the chief technology writer, said: "The reason why these batteries expand is the electrolyte degradation between the encapsulation, which will become a gas when degraded. Now the electrolyte is degraded, and things are no longer insulated, so they start short-circuit, which will lead to hotspots later.

This will eventually lead to thermal out of control, which means it may even trigger a fire. "The most common cause of battery expansion is excessive charging. Shi said that keeping the battery in a high charging state can bring pressure to it, degrading it faster.

Lenovo Chief Engineers and Strategic Technical Director, Philjakes, said: "In the system 24/7 all-weather inserted applications, the possibility of battery expansion will increase after many years. The other thing that drives it is calorie. The battery does not like to heat, when the battery temperature exceeds 100 degrees, the chemical process will start.

"Another common reason is the mechanical damage of the battery. This may be because the laptop itself has been blown, or damaged when replacing it (or disrupts other components around it). The hard surface and make the shell recesses cause expansion, which will be the same at over-high temperatures.

In addition, damage caused by the outside of the device may be transferred to the battery and cause the battery overheating and expansion. If your laptop is easy to open (in other words, it has a simple screw at the bottom of the chassis), you can remove the bottom cover, in many cases, inspect the physical state of the battery in this way. If it looks swollen or round, this may mean it swelling.

The most important thing is: Be careful when checking if the battery is expanding, because the battery is under pressure. Wear goggles, do not poke or kill cells. Dell Battery Expansion This expanded battery actually leads to the touchpad projecting from the keyboard panel of this laptop.

(Photo: Tony Hofman) Swelling battery is not always obvious during or at the beginning. This depends on how much it is expanded in the laptop chassis. For thin laptops, usually very few or no.

The size of the expansion battery can be placed from a small convex to a seesaw, even pop-up touchpads. (Yes, we have seen it. How to fix and prevent battery expansion? Once the battery begins to expand, it is likely to continue working with a lower efficiency.

Or, your laptop may just continue working in plugging in an AC plug, but will soon power out or power out after unplugging the power cord. In the end, don't ignore it; the battery will not work properly. Once you start to expand, you can't reverse it.

Your unique solution is to replace the battery. Of course, according to the experts of our interview, some methods can prevent this situation, or first: don't let your equipment have been plugged in. The battery is periodic, must be discharged and charging to work effectively.

Put your laptop in a cool, dry environment. Inflammatory, wet weather conditions, will bring greater pressure to the battery, and shorten its service life over time. When purchasing a new battery, please buy from a reputable manufacturer.

Usually, it is best to buy alternatives from the original laptop manufacturer, not from the third party to buy the cheapest compatible options. If the battery is old or exhausted, and the laptop can replace the battery itself, please replace the battery. Manufacturers test their batteries for three to four years, in the ideal case, the battery will not degrade, but they will.

If you start to see the signs of battery damage, expansion or depletion (in the last case, it can only stay a short time), please replace it now, not later replacement. This is not all bad and melancholy. Dell and Lenovo and other manufacturers have been committed to using smart battery technology in their laptops, allowing the battery to track their usage throughout the day to avoid overcharge.

Take Dell as an example. Dell's outstanding engineer and technical strategist Rickc.Thompson said: "The battery will continue to monitor how you use the system and place you in these different modes.

If the user allows us to control the battery based on the context-based charging, we will not fully charge it. We charge it to 80% to 90%, and it is only filled before the next day. "How to replace the laptop battery? Modern notebook can be accessed (ie, can enter the casing and replace the battery) is a very complex package.

Most laptops are different, slightly different, some are just equipped with non-replaceable batteries because the chassis is not open. For Apple's MacBook, some of the Ultrabook running Windows (especially some Microsoft SurfaceLaptop models) and some Chromebook, sometimes you can't replace the battery. Therefore, the first step is to talk to your laptop's technical support staff to learn about your choice.

If your battery begins to expand, it is time to take action. When evaluating the battery expansion, perform the following steps: Evaluate if you can even touch the battery. Contact your laptop manufacturer's support hotline or online resources for your product, ask your choice through "official" channel.

Some popular models have (unofficial) online tutorials to display battery replacement process. View the warranty range, and whether it still applies. (Unless you pay for the warranty period, the answer may be negative for a few years later.

Please note that if you have enough confidence to try yourself to replace the battery, if there is any remaining, you may make the warranty invalid. In addition, sometimes the battery warranty of the laptop is shorter than the main laptop itself. Keep reality for the conditions required to complete the work.

If you want to try it yourself, please don't try only to use any old tools to fix. You may need one or two special screwdrivers (star screws are very common on your laptop), and IFIXIT and other websites sell special kits suitable for Mac and other machines. According to the different products and manufacturers, the expanded battery may be the kiss of certain laptops.

Thompson said: "The battery can have a UL list or level to determine if they are suitable for customer service or customer technical personnel services. "The most important thing is to back up all important data as soon as possible in the first signs of the battery, and stop using laptops. How should I handle the expanded battery? The only way to handle old, expanded batteries is to process it.

When using a lithium-ion battery, be careful to avoid the battery when processing the battery or taken out from the PC. Do not use metal tools, or bend batteries in expansion. (Metal tools may pierce the outer skin and trigger chemical response; we mistakenly do this when replacing the old smartphone battery, and triggered some very small fires.

) The expanded battery also contains a gas you don't want to inhale. If you replace the battery yourself, please use it immediately after you take it. Do not discard the battery in the trash can or elsewhere.

This is an environmental taboo, and the sanitation workers that may contact the battery face health hazards. Always handle battery (whether or not expansion). Your system manufacturer can provide you with clues for disposal processes and locations.

In addition, fast Google Search should point you to the correct battery processing site. You can also contact your local government and waste processing department for instructions. Large retailers may also be the simplest way, depending on where you live.

"I strongly recommend that people bring them to Best Buy, or the local [technology] retailer, even there is a home of the [battery] recycling box," Jack said: "Even good lithium batteries will also cause serious on waste logistics. destroy. "Enjoy your equipment and lithium-ion batteries and their new intelligent upgrades, but please pay attention to carefully and respect them.

Otherwise, it may not only the battery needs to be replaced.
