With the continuous feature-rich mobile phones, MP3, MP4 mobile phone, camera, GPS navigation laptop battery capabilities have increased, consumers for mobile phones tend to demanding requirements of standby time. Despite the many ways to improve standby time, but the most direct is to enhance the battery capacity. At present, the ultra-long standby, super-capacity batteries have become another China-made mobile phones a strong selling point. However, with capacity increasing, more and more and more problems appear. Experts said the increased capacity at the same time, increased security risks along, especially capacity of more than 2000mAh (milliamp hours) battery. This year in January, the Shenzhen Municipal Bureau of Quality Supervision mobile phone battery manufacturers conducted spot checks, the reporter learned from the Bureau of Quality Supervision, test results released to the business first, and then for IBM FRU 92P1141 Battery review, eventually to the public.

Large capacity, risk might also

February 15, the Beijing Municipal Industry and Commerce announced that 16 kinds of mobile phone battery discharge and cycle life because of two failed to withdraw from the Beijing market. Some failed batteries for Motorola A1200, E398, Samsung E428, and some for Dopod 838, Philips cell phone brand and model.

Reporter to the identity of buyers visited a number of cell phone stores in Shenzhen city, found that ultra-long standby current play, large battery capacity of mobile phone brands a minority, 3000mAh or even higher capacity, ultra-high-capacity mobile phone batteries are also common. In a digital mall, there is a business directly to journalists recommended 4000mAh battery, and said large-capacity battery is now easy to sell. The reporter questioned its safety, the shop owner said that a lot of goods sold, never worked well. It is understood that the nation's largest mobile phone certification body CATR CTTL, although have examined 3000 ~ 4000mAh large capacity mobile phone battery, but not a high specification by testing. At present, the industry mainly 2000mAh battery products below are mostly below the capacity of 1200mAh IBM FRU 92P1137 Battery technology is relatively mature, while the 2000mAh or more cell phone manufacturers are often tailor-made, as for more than 3000mAh battery in the regular cell phone manufacturers there is seldom used. Experts said that mobile phone manufacturers in the use of more than 2000mAh batteries when the current process should be carefully considered to avoid the less mature processes result in security vulnerabilities. One battery manufacturer person in charge said, 2000mAh battery, if the above short-circuit lead to disastrous consequences, its destructive power no less than a small bomb. Regular mobile phone manufacturers and battery manufacturers are well aware of this risk is generally not going to take this risk. "4000mAh or more virtual mobile phone batteries IBM 02K6651 Battery are basically the subject of counterfeit products, because did not qualify for the national compulsory 3C certification license." Says one industry.

Capacity real life? Gimmick only

When this reporter visited the learned, the general configuration of the regular cell phone battery manufacturers concentrated in the 650-1200mAh, between which the 800-1000mAh-based. However, most non-original brand of battery capacity more in about 1200-1500mAh.

Market participants pointed out that the original brand battery power including professional manufacturer of batteries, for quality and process control are more stringent, the factory through the layers of test performance in a safe secure, there is a problem, firms will also be addressed in a timely manner , consumers can rest assured to buy. However, some fake plants in order to meet consumer demand, the introduction of more than 4000mAh battery, because of process control is not very good, on the other hand there may be refurbished second-hand batteries, without the authority of the department, a lower IBM 02K6928 Battery safety factor.

"Though they are marked with 4000mAh, perhaps even the 2000mAh are actually likely to reach." Shenzhen Electronic Chamber of Commerce Deputy Secretary-General Chen Yang pointed out that, due to accelerated replacement cell phone, it is often this kind of technology, such as battery capacity indicator is not pay attention to, not to hold the battery to the authority of the department for testing, so some unscrupulous manufacturers have already started virtual standard battery capacity, this as a gimmick to mislead consumers. In the current technology level, the average cell phone battery capacity peak so far of 1000mAh, thickening can be achieved through the 1700-1800mAh. Capacity of more than 3000mAh batteryIBM 02K6620 Battery manufacturers in general difficult to produce
