Understanding Batteries

A battery is a device consisting of one or more cells that can produce a direct current by converting chemical energy into electrical energy.

A motorcycle battery is made up of a plastic case containing six cells. Each cell is made up of a set of positive and negative plates immersed in a dilute sulfuric acid solution known as electrolyte, and each cell can hold a voltage of around 2.1 direct current (design dependent) volts when fully charged that are linked together. A fully charged battery of about 12.6volts is produced when all six cells are connected together.

Each cell consists of lead plates that carry either a positive or a negative charge. The positive ones are mostly made from lead dioxide and negatively charged ones are typically made from spongy lead. Depending on quality and cost, lead material can be chosen. The plates are arranged positive-negative-positive pattern, with an insulating material to prevent contact between plates. The insulation material is usually treated paper or fiberglass. Battery current capacity is directly related to the number of plates. More the plates or larger the plates, the flow of electricity will be much more.

In a typical cell, all positive plates are connected to each other, as are the negative plated. Further each cell is connected to neighboring cell in series-positive to negative, negative to positive.

For chemical a reaction to happen, an electrolyte which is a mixture of distilled water and sulfuric acid is added. When it reacts with the plates, an electric charge is generated.

As battery discharges, both electrolyte and lead plates undergo a transformation. I.e. electrolyte turns in water and lead plates are coated with lead sulfate eventually battery goes dead. To delay this process, the battery needs to be recharged by an external power source. In this case, the electrical system of the motorcycle is used which can produce higher voltage than the battery, restoring the battery to its original chemical state.

Though they are popular, they have drawbacks such as:-

  • They are filled with highly corrosive liquid
  • They produce hydrogen gas and require venting
  • They require periodic topping up of water as it evaporates which if neglected impacts battery's ability to hold charge.
  • They have to be mounted vertically to prevent leakage

Due to these drawbacks, an another type of battery was created known as Valve regulated lead acid or "Sealed maintenance free batteries"
