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
