Does your laptop battery burn?

When photos of laptops were caught on the Internet, news that many giants had to recover lithium-ion batteries, you could wonder if you could trust the existing mobile devices of 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 are recalled containing the cells manufactured by Sony Energy Devices of Japan. There was an error in the production process, so there are still very rare and even hot cases of battery burns (Dell reported 6 cases and Apple - 9 cases).

Does your laptop battery burn? Picture 1 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 flare occurs.

Of course, if these measures work well, Dell will not have to recover the battery this time, but an organization thinks this is the biggest recall in history (and Apple is second). Sony said other batteries, including batteries in Sony VAIO notebooks, also use faulty batteries, but achieve 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 has not ended, 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 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 also 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.
