Parts that store electrical energy affect the performance of the electronics and the working hours. In general, rechargeable batteries have a common electrochemical property, that is, the chemical reaction is a reversible reaction, and the power can be converted into chemical energy by an external power source to restore the discharged battery to its original state. Conversely, if the chemical reaction is irreversible, the battery cannot be charged, as is the case with dry batteries. However, if several batteries are charged in series, precautions are required. Because of changes in temperature or battery life, there is a slight difference in voltage across the battery; moreover, the more the battery is connected in series, the greater the difference in terminal voltage.
