The importance of the poles in a battery: positive and negative
Inside a battery, there are different components that allow the generation of electrical energy. One of these components is the positive pole. When the electrical circuit is completed, the chemical reaction at the positive pole produces an accumulation of electrons at this end of the battery. Characteristics of the positive terminal of a battery

4. DC wiring
This feature generally will only compensate for voltage losses up to 1V. If the losses in the system are bigger than 1V (i.e. 1V over the positive connection and 1V over the negative connection), the battery charger, solar charger or inverter/charger will reduce its charge voltage in such a way that the voltage drop remains limited to 1V.
