2.2 car battery charging lead sulfate is converted to pure lead and lead dioxide having different energy states. When charging, the occurrence of the lead dioxide electrode oxidation-reduction reaction occurs on the lead electrode, car batteries reaction is: 2PbS04 + 2 H20 === Pb02 + Pb + 2H2S 0 4 rechargeable DC power supply is turned on, the powerful DC power supply Under the electromotive force, the positive electrode plate is divalent lead ions ongoing electrochemical reaction, electrons produced by continuously charging the DC source to the negative electrode, to form a continuous charging current, and an electrolyte to form a closed loop together. 3 car lead-acid batteries used correctly identify 3.1 car battery positive and negative markers are usually striking the car battery positive terminal marked "+" in the negative terminal labeled "-." If for some reason unable to distinguish the positive and negative battery car, you can use a multimeter to detect discrimination. Adjustment range of DC voltage multimeter to verify the stalls, the red pen then wholesale car battery and the black ground, when the multimeter indicate a positive voltage value can be determined red pen is touching the car battery positive, black pen contact is negative. 3.4 Start the machine using a car battery to start the engine when the car engine power can be generated at the moment of starting a strong current of 400A ~ 1200A car battery What makes a good, long continuous high-current discharge, can easily cause arched plate deformation, resulting in plates active material shedding, making the car battery temperature rises sharply accelerated electrolyte evaporation, shorten the life of a car battery. Therefore, when the car starts, the time should not be more than 5 seconds the car battery, start again interval should be not less than one minute, three consecutive unsuccessful start, you should identify the cause of the failure, no longer forced to start, avoid long continuous high current every time you start discharge, damaged car battery. How to charge the car battery, car battery, car battery Wei Lai Po provided by Shenzhen Wei Lai Po Battery Limited. Shenzhen Wei Lai Po Battery Co., Ltd.
