Lead Acid BatteryĪ completely charged battery can discharge its current when connected to a load. The positive plates hold pure lead as the active material while lead oxide is attached on the negative plates. The plates are divided into positive and negative plates. The plates have grids on which the active material is attached.
#TYPES OF BATTERIES SERIES#
The Lead Acid battery consists of a series of plates kept immersed in sulphuric acid solution.

Unlike tubular and maintenance free batteries, Lead Acid batteries require proper care and maintenance to prolong its life. Lead Acid batteries are widely used in automobiles, inverters, backup power systems etc. When battery is discharged, the cadmium reacts with NiOOH to form back nickel hydroxide and Cadmium Hydroxide.Ĭd + 2H2O + 2NiOOH -> 2Ni(OH)2 + Cd(OH)2 Lead Acid Battery: In the anode, formation of Cadmium ions take place from Cadmium Hydroxide. When the battery is charged, the chemical composition of the cathode is transformed and the nickel hydroxide changes to NIOOH. This battery uses nickel oxide for cathode, a cadmium compound for anode and potassium hydroxide solution as its electrolyte. The Nickel Cadmium batteries have the advantage of being recharged many times and possess a relatively constant potential during discharge and have more electrical and physical withstanding capacity. Li Battery Nickel Cadmium (Nicd) Battery: Also Special cells can provide very high current to applications such as power tools. And relatively low self-discharge batteries. These are the high energy density potential devices for higher capacities.
#TYPES OF BATTERIES PORTABLE#
The lithium battery has been one of the greatest achievements in portable power in the last decade with use of lithium batteries we have been able to shift from black and white mobile to color mobiles with additional features like GPS, email alerts etc. We all use it in portable devices such as cell phone, a laptop computer or a power tool. Battery manufacturers recommend against recharge of primary cells. Once these batteries are used they cannot be recharged as the devices are not easily reversible and active materials may not return to their original forms. 2 Types of Batteries 1) Primary Batteries:Īs the name indicates these batteries are meant for single usage. Inverter battery should be placed on a wooden plank if possible. Automobile battery should be firmly fixed in the vehicle to avoid shake. The terminal voltage of a completely charged battery is12V, automobile battery shows 13.8V in its terminals while a 12 volt tubular battery will show 14.8V. Equalization can be done by marginally over charging the battery to allow the weaker cells also to charge completely. Due to aging, all the cells do not charge similarly and some cells accept charge extremely fast while others charge gradually. To maintain the battery in good condition, battery equalization is necessary. In this way, if the electrodes have emf and in other words, the net emf is the difference between the reduction potentials of the half-reactions. The net emf of the cell is the difference between the emf of its half-cells. Each half cell has an electromotive force (Emf), determined by its capacity to drive electric current from the interior to the exterior of the cell.
