The positive and negative poles are connected to charge, which can cause the battery to reverse, and the repair method is to empty the battery power of the reverse pole, and then carry out high resistance repair according to the original positive and negative poles, increase the voltage to more than 10V, and then charge, full of it. Antipole;
(1) refers to the polarity of the individual single battery when assembling the battery pack is contrary to the provisions of the product design;
(2) refers to multiple battery cells connected in series due to overdischarge, the positive potential of individual small capacity battery cells is lower than the negative electrode. If the battery is reversed for a long time without correction, it will fail or even cause an explosion accident.
