Lead Acid battery Choosing For Final Year Project

Batteries are an integral part of robot design, as important as the frame, motor, and electronic brain. Batteries come in all sizes and shapes .So, an appropriate choice has to be made depending on the application .If the application demands high current and longer period of operation lead acid battery is a good choice. Although Lithium ion battery would be a ideal choice for our project it is very costly when compared with lead acid battery .Since our design can carry heavy weights we decided to use lead acid battery for its cheap availability even though it is heavy.

Lead acid Battery Types Usage

LEAD-ACID BATTERY

Lead Acid batteries were developed in the late 1800s, and were the first commercially practical batteries. They remain popular because they are easy and inexpensive to manufacture. Rechargeable lead-acid batteries have been available since the 1950s and have become the most widely used type of batteries today.

There are three main types of lead acid batteries.

Wet Cell (flooded)

Gel Cell,Absorbed

Glass Mat (AGM).


The Gel Cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium wet cell. However they store very well and do not tend to sulphate or degrade as easily or as easily as wet cell. There is little chance of a hydrogen gas explosion or corrosion when using these batteries. Gel Cell batteries, which are best used in very deep cycle applications, still are being sold but AGM batteries are typically better. In most cases AGM batteries will give greater life span and greater cycle life than a wet cell battery.Why I choose Lead Acid for my project ,I've written in my next post .
