Mobile search car battery test procedureDate£º2014-1-7 Step 1: detect the chemical properties of the built-in battery is bad
1 Will have built-in battery full of charge. Windows Battery management display 100% 2 Disconnect the external battery, disconnect the battery output and the computer's connecting line. 3 Open the computer, the time began, until the computer automatically shut down after the computer, see a total of built-in battery How much is the use of time (battery discharge process)? If the power is within an hour or less , we can basically be identified as built-in battery chemical properties have gone bad! Second step : Detect the external battery charge 1 Disconnect the battery from the computer and disconnect the battery output wire.. 2 Power adapter for battery charge. When you see four of the front panel of the battery LED Indicator light When the battery is being charged in the flash 3 Four lights after six hours of battery LED The indicator should be all bright and no flash. ( At this point the electricity Pool charge ) The third step: results analysis The external battery is the supply of DC power to the internal battery and the circuit connection mode is serial connection, If built in The chemical properties of the battery (irreversible) lead to the internal impedance and make the external battery charge into the charge ; If the internal battery is good (internal impedance stable) and the external battery is full of charge, the full Normal use of computer.
