小本上中学后,每周一至周五要到学校上晚自习。为联系方便,爸爸给他买了手机。最近,小本的手机后面鼓了个包,后盖打不开了;手机刚充满电,用不了多久,电就耗完了。什么原因?懂电和电子产品知识的爸爸告诉他,这是因为电池坏了,需要更换新电池。原来充电电池还会坏呀!爸爸看小本一脸茫然的模样,于是给他讲了一些有关电池的知识。 Small primary and high school, every Monday to Friday to go to school for self-study. For the convenience of contact, my father bought him a cell phone. Recently, a small bag behind the drum phone, the back cover could not be opened; the phone just fully charged, before long, the electricity consumed. What reason? Dad know electric and electronic knowledge of his father told him that this is because the battery is broken, you need to replace the new battery. The original rechargeable battery will be bad ah! Dad look at the small face look blank, so he told him some knowledge about the battery.
