Battery Discharge:Discharging is always occurring inside a battery at any given time. The electrolyte solution contains charged ions, made up of sulphate and hydrogen. The sulphate ions are negative charged, while the hydrogen ions have a positive charge. When an electrical load is placed across a battery’s terminals (starter motor, headlight, etc.) the sulphuric acid breaks down, the resulting sulphate ions travel to the negative plates and react with the plate’s active material giving up their negative charge through ionisation. This cause the battery to discharge or produce electrical energy. This excess electron flow out of the negative side of the negative side of the battery,through the |
electrical device, and back to the positive side of the battery is what creates DC current. Once the electrons arrive back at the positive battery terminal, they travel back into the cells and re-attach themselves to the positive plates. The discharge process continues until the battery is discharged and there is no more chemical energy left. |

Battery Charge:Charging a battery reverses the chemical process that occurred during discharge. The sulphate and hydrogen ions basically switch places. The electrical energy used to charge a battery is converted back to chemical energy and stored inside the battery. Battery chargers, including alternators and generators, produce a higher voltage than the battery’s open circuit voltage. When charging amperage exceeds the level of the natural absorption rate, the battery may overheat, causing the electrolyte solution to bubble creating flammable hydrogen gas. Hydrogen gas, when combined with oxygen from the air, is highly explosive and can easily be ignited by a spark. Consequently, always remember to turn the power off before connecting or disconnecting a battery charger to prevent a spark at the battery terminals! |
