Longer life of battery –Forlonger life of battery, a cell should not be allowed to be discharged till voltage 1.8V & 1.1level of specific gravity.

Voltage & specific gravity – A fully charged cell has a voltage of 2.2V & specific gravity of 1.250 respectively.

Following chemical reactions take place during discharging of batteries -H 2SO 4 = H+(ions) + SO 4 – – (ions).

2) Lead sulfate of negative plate gets converted into lead peroxide & lead sulfate of positive terminal gets converted into pure lead. So, above process – 1) increases gravity of sulfuric acid& potential difference between two terminals.

These radicals react with PbSO4 & form PbO2 and H2SO4.

SO4 – – ions will attract towards positive terminal of battery &give up extra electrons become SO4 radicals,.

These hydrogen atoms attract PbSO4 and form Lead & Sulfuric Acid,.

As H+ ion is positive so it will go to negative side of the battery which is connected with negative terminal with DC source & H+ ion becomes H atom by receiving electrons from it.

Sulfuric Acid (H2SO4) remains in the solution of PbSO4 in the form of H+ & SO4 – -,.

Connect discharged battery with charger.

Now, Battery charging is done as per following procedure – The above process is called discharging of battery. The operation of a battery works on chemical reactions which can be understood from following diagrams. If 12V available between P&N terminals battery is ready for use, if voltage is less than 12V, then again charge it till voltage reaches up to 12V.

After sufficient charging, check battery voltage between positive (P)& negative (N) terminals. Sulfuric acid with water in 3:1 ratio is called electrolyte.Connect battery with charger & leave it for 8-10 hrs.

Let us follow this procedure – first fill the container with sulfuric acid (H 2SO 4). Now let us prepare battery so that it can be sued. When we buy a led acid battery, say, 12V, it comes in two parts – 1) battery with a container &two electrodes fixed with the container, 2) Sulfuric acid which comes in a separate container. The container is filled with Sulfuric acid (H 2SO 4)& major portion of positive & negative electrodes are dipped in the sulfuric acid & some portion of these electrodes are left out which are used to connect the load. A battery consists of four main parts – a) a container which can hold liquid acid, b) Positive Electrode – Led PerOxide(PbO 2) c) Negative electrode – Sponge Lead (Pb) & d) Electrolyte (Sulfuric Acid (H 2SO 4). LEAD ACID BATTERY – A lead acid battery is also known as tubular battery.

Batteries are of two types – Lead Acid Battery & 2) Sealed Maintenance Free (SFM) Battery They were popular for use in button-type battery applications, such as watches or hearing aids.Batteries – Lead Acid Battery charging & discharging process of battery maintenance of battery Health check of battery Lithium-ion battery AA & AAA battery car battery Car battery charging process What is battery – Definition of battery is given below – Definition –Ī container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power. Also, they had the highest capacity per size. In the past, these batteries were widely used because of their long shelf life of about 10 years, and also because of their stable, steady voltage output. The anode is made with zinc and is separated from the cathode with a piece of paper or other porous substance that has been soaked in the electrolyte (which is generally either sodium or potassium oxide). Mercury batteries utilize either pure mercuric oxide or a mix of mercuric oxide with manganese dioxide as the cathode. About 90% of the 1.4 million pounds of mercury in our garbage comes from mercury cells. This mercury is released into the atmosphere if the cells are incinerated in the trash. Mercury cells offer a long lifetime in a small size but the mercury produced as the cell discharges is very toxic. Mercury batteries are small, circular metal batteries that were used in watches.
