Laptop batteries are the "energy heart" of laptops. They allow us to use laptops freely anytime and anywhere. Whether we are working elegantly in Starbucks or happily watching TV series in bed, we cannot do without their support. However, in recent years, the fire hazard of Lenovo laptop batteries has been like a sword of Damocles hanging over the heads of users, making everyone worried. Therefore, it is very important to master how to charge safely to prevent fire hazards. Let me explain one by one.

Understand the charging principle    

Before we delve into safe charging tips, we need to first understand the charging principle of laptop batteries, just like understanding the enemy's tactics before going to war. Laptop batteries generally use lithium-ion batteries, which store and release energy through the movement of lithium ions between the positive and negative electrodes during the charging process. These lithium ions are like a group of hardworking little bees, shuttling back and forth between the positive and negative electrodes, carrying energy. However, like any precision instrument, lithium-ion batteries also have their own little tempers. Overcharging, overheating or short circuits may cause safety hazards to the battery and even cause fires, so we have to be careful.

Choose the right environment

Avoid high temperature environment: High temperature is the enemy of batteries. In high temperature environment, the heat of lithium-ion batteries will accelerate the decomposition, just like chocolate roasted by fire, it will soon melt and deform, increasing the risk of fire. So don't charge your laptop in direct sunlight or in a high temperature room, otherwise the battery will "explode".

Well-ventilated place: When charging, ensure that the surrounding air is circulating so that the battery can "breathe" freely. Good ventilation can effectively reduce the risk of battery overheating, just like installing a natural air conditioner for the battery to keep it cool at all times.

Keep away from flammable items: When charging, keep the laptop away from flammable items such as paper, cloth, plastic, etc., to ensure a safe distance to prevent sparks from flying and causing fire. This is like not being able to smoke at a gas station, you have to be careful at all times.

Use the original charger

There is a saying that goes, "A forced melon is not sweet, and an incompatible charger is unsafe." Using a non-original charger is one of the important factors that lead to battery safety hazards. In order to save money, many users choose to use cheap third-party chargers, which is like putting an inappropriate rein on a horse, which may cause voltage instability, over-fast charging and other problems, leading to various dangers. Therefore, using the original charger officially provided can not only ensure charging efficiency, but also effectively reduce fire hazards, allowing the battery and charger to cooperate "happily and happily".

Check battery status regularly   

Regular inspection is essential to keep the battery healthy and long-lasting.

Battery swelling: Check the battery regularly for swelling. A swollen battery is often a sign of damage . Using such a battery may cause a short circuit or fire, so it should be replaced promptly and not be taken lightly.

Charging time: Make sure not to leave the laptop battery connected to the charger for a long time, especially after it is fully charged. Although modern batteries have mechanisms to prevent overcharging, long-term connection may still increase the battery temperature , and the battery will "unable to bear" it .

Cable inspection: Check the power cord regularly for wear, cracks, etc. If any problems are found, replace it in time to avoid short circuits, which is a matter of life and death for the battery .

Pay attention to the usage during charging

Try to avoid using your laptop while charging, especially when performing high-load tasks such as playing games or video editing. This will put more pressure on the battery and increase heat, which will increase the risk of fire. So, when charging, let the laptop take a good rest and let it "show its skills" after it is fully charged.

Precautions when using the charger 

Socket selection: Make sure the socket you use is stable and the current can withstand the load of the charger. Avoid charging through unstable connections such as extension cords and power strips, otherwise it will be like walking on a shaky tightrope and problems may occur at any time .

Avoid humid environments: Keep the battery dry during charging and avoid using the power supply in a humid environment to prevent short circuits in electrical components. This is like not playing in the water on a rainy day. Stay away from water sources and protect the charger and battery .

Do not cover the notebook: Do not cover the notebook with clothing, pillows, etc. when charging to ensure ventilation and heat dissipation to avoid overheating. Otherwise, the notebook will be like having its mouth and nose covered, unable to breathe, and will become "sick".

Understand fire emergency measures

Although we can take a variety of preventive measures, timely emergency response is crucial in the event of a fire.

Disconnect the power supply immediately: If you find that the battery is smoking or has an odor, you should immediately disconnect the power supply to avoid further charging. This is the most basic common sense, just like finding that the house is on fire, the first thing to do is to cut off the fire source.

Use a fire extinguisher: If the fire is small, you can use a fire extinguisher to put it out. Make sure to use a fire extinguisher suitable for electrical appliances, such as a carbon dioxide fire extinguisher. But if the fire is large, don't try to be brave, and run away as soon as possible.

Escape route: When a fire occurs, stay calm, quickly find a safe exit, and call 119 if necessary. Don't panic at this time, you must be like Zhuge Liang, who was not afraid of danger, so as to turn danger into safety.

Improve battery life   

In addition to safe charging, proper maintenance can also extend the battery life and reduce fire hazards.

Calibrate the battery regularly: Performing a complete charge and discharge cycle at regular intervals can effectively increase the battery's cycle life, just like giving the battery a comprehensive physical examination, allowing it to serve us better .

Moderate charging: Try to keep the battery level between 20% and 80% and avoid keeping it at 100% for a long time.

Update drivers: Keeping your laptop's drivers and system updated can improve battery efficiency and reduce the risk of overheating. Keeping your laptop young at all times can help it perform better.
