![]() ![]() A full charge restores the chemical difference between the plates and leaves the battery ready to deliver its full power. You can recharge a discharged battery by feeding electrical current back into it. Eventually the battery is so discharged that it can no longer deliver electricity at a useful voltage. This happens when you're driving without any accessories and the alternator puts current back into the battery.Īs a battery discharges, the lead plates become more chemically alike, the acid becomes weaker, and the voltage drops. In the reverse process, a battery becomes charged when current flows back into it, restoring the chemical difference between the plates. When a battery is connected to a load that needs electricity, such as the starter in your car, current flows from the battery. Most people don't realize that a lead-acid battery operates in a constant process of charge and discharge. This happens when any load that needs electricity, such as the radio, is connected to the battery. Electricity flows from the battery as soon as there is a circuit between the positive and negative terminals. In a typical lead-acid battery, the voltage is approximately 2 volts per cell, for a total of 12 volts. ![]() It develops voltage from the chemical reaction produced when two unlike materials, such as the positive and negative plates, are immersed in the electrolyte, a solution of sulphuric acid and water. A battery stores electricity for future use. ![]()
