FAILURE MODE & EFFECT ANALYSIS OF LEAD ACID BATTERY

Now a days Reliability of any mechanical system is the most important factor of the product design, so the need for reliability estimation & prediction of critical modes of failure for mechanical system became the talk of the town. Lead acid battery which has been in use for different applications for over 13 decades. Their areas of application have transcended the traditional areas of automotive vehicle and have spread to newly developed area such as in traction of hybrid - electric vehicles, in un - interruptible power supply units and in telecommunication system for standby duties. The objective of this paper is presents the failure mode its severity, their effects on the service life of Lead Acid Battery. The Risk Priority Number (RPN) of the automobile battery based upon the failure data from a battery . This is very useful to underst and Battery faults & maintenance.
