Does your laptop battery burn?

When photos of laptops were caught up on the Internet, news of a lot of giants had to recall lithium-ion batteries, you wondered if you could count on your existing mobile devices. I don't. There are billions of batteries that supply everything, from mobile phones to camcorders . And the tendency to squeeze more energy into such a tiny lump is increasing, which further worsens the outlook. for safety when using mobile devices.

Rare occurrence

All of Dell's 4.1 million lithium-ion batteries and 1.8 million Apple batteries were recalled containing the cells produced by Sony Energy Devices of Japan. There was an error in the manufacturing process, so there are still very rare and even hot cases of batteries that can catch fire (Dell reported 6 cases and Apple - 9 cases).

If you are doubting the battery of your existing mobile devices, don't worry. Experts say that even if the battery generates 2 or 3 times more energy than a normal rechargeable battery, it doesn't mean that the battery is not safe. The battery also incorporates multiple layers of internal safety monitoring based on CPU and sensors, along with control technologies such as discharge valves and chemical fuses. Normally, problematic batteries will automatically lose energy when there is a short circuit, before any excessive temperature rise or burning occurs.

Of course, if these measures work well, Dell will not have to recover the battery this time, but as an organization thinks this is the largest recall in history (and Apple is second). Sony said other batteries, including batteries in Sony VAIO notebooks, also use faulty batteries, but they have a safe level and Sony does not plan to recover the battery. Anyway, when there is a potentially dangerous battery, Sony must change the production process to fix it.

The actual number is different

Will your laptop explode? The number of external explosive battery statistics is many times higher than that reported by Dell, even up to 50 times (a total of 300 cases); This means that for every 1000 batteries, 1 battery will burn or overheat during battery recovery. According to Dell's calculations, the company released a total of 24.9 million batteries from April 2004 to July 2006; and Apple - from mid-October 2003 to August 2006.

Every day there are still risks of lithium-ion batteries and battery recovery is still not over, although manufacturers are still trying to design safer batteries. But if you comply with the battery safety promotion shown on the packaging, you may be able to avoid the risk.

Safe for batteries

1. To check if your laptop battery is safe, go to (Dell) and (Apple). If your battery is on that list, it's best to remove the battery and use the power directly from the adapter until you receive a replacement battery.
2. Other brands' cheap batteries that you buy may not be safe, so be careful when buying. Batteries from the same laptop manufacturer are often the best option.
3. Use the charger adapter used specifically for that type of battery.
4. Do not leave the device or battery in hot weather, or anywhere with high temperatures. High ambient temperatures can increase battery overheating.
5. Bumps and pressure are another risk. Dropping a laptop can cause problems like Panasonic's recent battery recall.
6. Do not carry a battery in a key bag or other metal objects, or a large bag, whether or not the battery is charged because of a short-circuit risk. You should leave the battery in a battery case or a separate case before putting it in a bag.
