Mobile explosion killer (see previous newspaper reported yesterday), this black "humor," laptop battery took place in celebration of the Lunar New Year appear to be more concern. Many readers suspect that the deceased used the cottage version of the battery. "Why is The frequent occurrence of cell phone explosion, an unsafe laptop battery batteries in the end?" Many people surprised by the issue of doubt. Yesterday, the reporter visited the part of the laptop battery sales distribution center, in consultation with experts in line, perspective of the chaos like a laptop battery battery market.

● telecommunications experts culprit cell phone battery is low-grade explosive

Retrospectively from around the laptop battery explosion case, the quality of laptop battery batteries, but customs are often the culprits.

"Cell phone circuits and electronic Compaq PP2100 battery components from the principle of speaking, is not possible explosion, the main problems lies in the batteries." South China University of Electronic and Information Engineering, Professor Sui-Li Feng, CATR CTTL Jiang Jing Xin, etc. experts explicitly stated that the quality of laptop battery batteries, but customs is the laptop battery explosion frequent culprit.

Experts point out that in general laptop battery battery explosion is mainly caused by batteries, the battery positive and negative poles of the batteries need to enclose a layer of insulating film, and there are auxiliary protection circuit to improve security. If the battery is designed to unreasonable or manufacturer cut corners, such as the use of heat-resistant insulating film properties, however, or simply do not set off the protection circuit, battery over-charging and discharging, or by external effect of heat stress, it prone to short-circuit, thereby breaking the shell explosion. In addition, the laptop battery Hp DP390A battery is placed next to high temperatures or flammable materials may also trigger an explosion.

Late last year, the provincial Trade and Industry Bureau released the third quarter of Guangdong circulation cell phone batteries, cell phone charger, wire and cable products such as the quality of sampling report. The results showed that cell phone batteries pass rate of less than Liu Cheng, substandard products are mainly due to manufacturers cutting corners, using inferior parts caused. Places to sell the distinction between the professional market, the lowest passing rate of laptop battery accessories.

● Market of the battery is hard to tell the difference on the pros and cons of hundred

Experts suggested that for safety reasons, we should make full use of Hp HSTNN-UB02 battery original equipment batteries. Reporter yesterday visited the site and found the market is quite confusing variety of laptop battery battery, good and bad for consumers is hard to tell. Samsung slider phone with a reporter's asking price of 800 milliamperes original equipment batteries, as many as on the hundred dollars difference. Longevity Road in Guangzhou, a telecommunications operator in stores, selling 160. Cemetery Road in the laptop battery market, a shop, laptop can go for 35 yuan, higher than some imitation original battery and domestic battery also cheap.

"35 yuan an original battery, Why is it so cheap?" The owner said it was "parallel machine" with batteries, but they mainly do wholesale, the price discount. Since it is a parallel, that is, sold in Hong Kong or abroad, but the reporter noticed that the battery is printed on the "Samsung (Tianjin) Corporation to create" the word has almost become a "routine" the appearance of the battery Hp HSTNN-DB02 battery.

It is understood that the relevant state regulations require cell phone battery overcharge, over discharge, or when an external short-circuit protection, fire does not appear the explosion occurred. The reporter saw a number of domestic non-original battery box on the prompt, "Do not over-charging or near the high-temperature objects, in order to avoid an explosion," the battery can not help but doubt whether the quality of compliance.

● "three noes" cottage version of the phenomenon of increasing cell phone disorder

What is more worrying is that a large number of the long Hp 346970-001 battery standby time as a selling point of the cottage laptop battery, with its derivatives with high-power cell phone batteries, high-risk and the lack of supervision.

Cemetery Road in a store, a woman's shop waves enthusiastically recommend 3 "native" laptop battery. Large screen, high-five million pixel camera, dual sim dual standby feature, but only sell more than 600 yuan. In addition to "CF", "qq" and other simple logo outside, and can not see the production of laptop battery brands and factory name. Similar to the laptop battery handset sales in each market, everywhere.

Some experts believe that the structural principle from the phone point of view, the proliferation of cottage machines and does not directly cause the Hp Omnibook XE3 battery explosion of growth. But the bulk cottage cottage machine causing chaos in the battery, it should be attention. "Some of counterfeit batteries, although with great power, but when the danger to internal, the internal pressure to accumulate considerable energy, they lack the formal structure of the battery of effective relief, you break through the hard shell explosion." Jiang Jing Xin analysis.

● how to regulate the battery difficult to uniform standards, the key is to implement the regulatory

In 2007, CTTL CATR was first mooted introduction of a unified standard cell phone batteries. At that time, any Gui Li CTTL the main idea of the laptop battery battery as dry as the standard classification, just as dry there are several different models the same size and applied to all laptop batterys.

Today, a unified laptop battery batteries are not yet a real progress. Professor Feng Suili that although the existence of common standards for the battery models, there is no unified brand and unified battery capacity. laptop battery battery, as an important component of laptop batterys, instead of linked models and brands, also contributed to difficulties in standardizing its causes. For example, some foreign laptop battery brands, the same models with any batteries, in China and overseas sales of products are the same, and if China wants reunification battery Hp F2024A battery standard is bound to the entire production line must be changed, it would lead to "affect the situation moving body. "

Professor Feng Suili that, it is imperative that by strengthening the supervision of quality assurance. "Many dealers promotional activities are to buy a laptop battery distribution two batteries, of which one is the original, and the other piece is the other brand or counterfeit batteries. In this regard, the state has not yet put in place policies on the regulation." Xie Yu-Min CAI
