(3) to measure the relative density of the electrolyte, such as fluctuations in the density 3h no longer toys charger, up to the maximum, then the charging is completed. Zhejiang Sheng Lee charger electronics company quality assurance, is your best choice. Car battery in our lives has been widely used in toys charger manufacturer, that we use in order to process more smoothly, we need to understand some simple maintenance methods. Here Lee Sheng Electronics Co. to introduce you to: resistance method: using a digital multimeter, suspected part of the circuit is measured, generally we use to measure speed diode 12v charger toy is shorted two leads, that file will be called a multimeter to measure former resistance we will do the necessary discharge behavior, make sure no plug in the mains, we go one by one with tweezers short circuit some capacitors, capacitor discharge will be issued when the sparks and noise do not be afraid, then we are the resistance on the road measurement.
