Mobile phone battery exploded while charging, causing the left Laptop Battery eyeball burst. Press survey found that prices of mobile phone battery a far cry from more than one or two hundred yuan to have. Insiders pointed out that ten to twenty million "non-brand batteries" Ba Cheng holds an estimated market share of cheap steel core as they are often taken for battery core, easier explosion, power is greater.
Modified cells fend 5 minutes
Reporters interviewed found that prices of mobile phone battery a far cry from the big brands laptop battery with original equipment batteries frequently one or two hundred dollars, but in the electronic communications market, brand-name batteries are only ten to twenty million in the mid-price brand of battery will have to 50 or so. Amoy Street in Zhongshan Road, 6 appliances in the city, the reporter saw a market stall, hit the "on-site modified cells, the extraordinary stand-by 3 to 7 days" signs. Ran into a public holding a swollen battery question can repair. "May," answered clerk while the battery outside edge stickers stuck ripped apart inside the battery cell out from under the counter and come up with a new battery cell, and then carefully to protect the battery cell and battery on a Plate Welding , 337607-001 laptop battery and then voltage device testing, see the voltage to the "3.7V", the would readily come up with a printed "NOKIA" stickers to re-word the battery pack is good, the whole process less than 5 minutes, changing the core charge 15 yuan .
Plastic membrane shell safer batteries
Doing battery production in Shenzhen, Mr. Wang said more than ten years, if you want a full-fledged production of batteries, the cost generally 15 to 20 yuan, the retail price will certainly be more than 30 yuan, so ten or twenty dollars cheaper batteries will certainly cut corners, using poor quality of the battery cell.
"Battery cell sub-steel, aluminum and Pavilion ZT3000 laptop battery aluminum-plastic film, steel and aluminum cheaper." Mr. Wang said the steel strength of the highest and most dangerous, because steel is not easy to deformation, resulting in expansion deformation, the internal has been the accumulation of a lot of gas, once the powerful blast up on the large, "like the same shell." The deep-fried blind Mr. Chiang's battery, is the steel battery. At present, some big brand manufacturers to use aluminum battery shell membrane, the relative safety of a lot, but the cost of two expensive than the steel into the market share-less than one.
Modified cell is like a grenade
One battery manufacturer, said modified cell phone batteries are very dangerous, because they are modified, the battery's voltage characteristics have been EX942AA laptop battery changed, leading to the collection of inaccurate battery display, combined with the modified heat may cause the problem, which is an laptop battery important reason for the explosion.
Quality and technical supervision departments to remind: The new battery charger for the first time when hand-to-case temperature is too high, generally the initial battery charge (1 hour) will be fever, but the temperature will not be too high; after the temperature will be close to the ambient temperature; if charging a hours later, the battery case temperature is high (hot), there may be problems with battery charging protection circuit for safety reasons, should be discontinued. Also, do not frequent charging, to avoid prolonged charging, full can. If the battery is accidentally hit Shuaiguo or too heavy, do not rush to charge, be sure to check whether there are cracks the shell of the battery, charge the EV087AA battery case temperature when you pay attention to whether an exception in order to avoid damage to the internal protection circuit caused by accidents.
