standard cell phone battery performance
Cell phones should be in line with the standards which
A standard cell phone battery performance should be as follows:
Appearance: cell surface texture color clear, uniform, clean, no scratches and damage; Dell Inspiron 500m battery labels should be printed on the battery type, the type, rated capacity of the standard voltage, the signs are negative, the manufacturing plant, 000. On the phone when they want to handle non-blocking smooth, elastic appropriate, and with good hands, a reliable locking; metal piece no scratches and black hair is green.
Battery Performance: standby time, talk time is actually a relative concept, test the Dell Inspiron 510m battery capacity of the consumer is a comprehensive, that is, standby, talk time at the same time. Simply put, the battery's rated capacity should not be less than the standard size of 95% of the full power to place 28 days, the minimum capacity of not less than 60% of rated capacity, battery life of less than 400 times.
Safety: cell phone Dell Inspiron 600m battery over-current protection should be internal, external, and so lead to short-circuit current is too large, automatically cut off the loop, so as not to burn or damage to the cell phone; lithium-ion batteries have been sufficient to protect the other line, when the use of non-standard electrical appliances , To pay too much electric current when the power supply will automatically cut off, do not charge into the lead in normal cells, can automatically back to the turn-on status.
Termination of the charging control functions: mobile phone Dell Inspiron 6000 battery should be an internal temperature sensor, battery charger to charge for the provision of temperature signals the end of the charging control.
Production technology and raw materials: the production of cell phone technology is not complicated, but why cell phone market, the passing rate so low? Here there are two main reasons: First, manufacturers in pursuit of illegal profits and reduce costs, lower prices in order to scramble the market, used improper means to use defective materials or even scrap the assembly cell phone Dell Inspiron 630m battery; and the other is in the process of cell production of a number of key Factors have not been strictly controlled and to use components caused by incorrect parameter, so consumers should be chosen carefully to identify their true strengths and weaknesses
How to identify genuine and fake mobile phone batteries
At present, the cell phone of the brand has many good and the bad. However, there are a lot of the market is flooded with fake batteries so that consumers can buy batteries when difficile truth, not to gain the upper hand. In addition, some illegal phone dealers, the sale of real cell phone equipped with mobile phone batteries, in order to reap illegal profits. Short battery life is not only false but also because of damage to voltage instability in the highly mobile phone. Consumers should be in the following areas to identify the authenticity of cell phone batteries. Dell 1691P battery
First, the length of standby time
Battery standby time is a measure of the length of the pros and cons of an important indicator of Dell 3149C battery. Battery standby time is the length of the battery constitutes a single battery charge of the balance of the decision. Really battery standby time and a detailed description of the logo should be basically the same. The false identification only half the time. The number of poor-quality batteries are used in the secondary Dell Y9943 battery for core kernel, together with the new packaging by the assembly. If the seller does not guarantee standby time in line with the prospectus, you will not be able to buy the batteries. Some sellers in all sincerity and seriousness, in fact, he did not know the actual battery capacity, more than just oral. This Dell 6Y270 battery is generally poor quality of cell manufacturing. If the purchase of stand-by found a short time, the request should be returned immediately.
Second, the battery capacity
Cell phone batteries for the general capacity of 1000 mA / hour or two 1000mah. Some did not leave the battery capacity of the logo, the logo has also illegible. Can also get the battery cell phone repair shop to measure current, so as to the authenticity debate. Now we are using lithium batteries, lithium batteries and is similar to sections 5 and 7, the size of the batteries together, with switchgear and protection of the circuit. Therefore, it has a certain weight. If you buy a lithium battery light on the core battery capacity, the batteries may be a problem. General 900mah lithium battery core weight 35g, if a piece of the Dell 75UYF battery cell batteries and other equipment and lack of casing the weight of 35g, this battery that may be false.
Third, security
Cell phone Dell U4873 battery are flammable and explosive materials, if not an internal battery protection circuit, easily deformed, leakage, or even an explosion. However, many low-quality batteries at low prices to attract consumers to remove the piece of circuit board protection, in order to earn greater profits. This market has a lot of unsafe batteries, it is difficult to identify from the appearance. The best time to buy a regular mall to buy Telecom.
At present, the market's three main mobile phone batteries: Lithium-ion batteries, nickel-metal hydride batteries and nickel batteries. As a result of the largest-capacity lithium-ion batteries, long standby time, light and mobile phone battery is the main species. So, above all lithium-based Dell TC023 battery
In high-Ju (600,872) low-power battery cell replication Desai
BYD to attract investment in Buffett Bao Zhang, as well as short-term stimulus, the A-share market again today to start the hp dp390a battery plate, today is far to branches force, headed by Desai, such as battery power batteries subject to collective shares trading again broke out of the market One of the few bright spots. Their common characteristic is that production and BYD as the nickel-hydrogen toshiba pa3285u-1brs battery used car!
