Batteries are the backup power source for millions of consumers and businesses, as well as medical, military, and industrial facilities worldwide. Critical applications such as computers, servers, instruments, telecommunications, and life-saving equipment require one hundred percent redundancy in every aspect to ensure a high degree of reliability and operation. Although commercial power supply sources are available, any malfunction or interruption of the utility power can be detrimental to the critical operations of the facility. Thus, consistent and reliable performance of batteries is essential for smooth functioning of modern equipment.

In the U.S., battery replacement is a seventeen billion dollar market. Around seventy-five percent of these batteries-whether "starting," "power," "stand-by," "industrial," "marine," etc.-have stopped working prematurely due to inadequate maintenance, while the remaining twenty-five percent suffer mechanical failures. The number one cause of reduced lifespan and output capacity in batteries is attributed to "over sulfation," a crystallization that occurs when a battery cell is undercharged. Ongoing maintenance of batteries is thus very important.

This course provides basic engineering guidance in the operation, maintenance, diagnostics, and testing of lead-acid and vented nickel cadmium batteries. The course is applicable to all electrical, mechanical, and facility engineers, energy auditors, and operation and maintenance personnel responsible for power provision at your facilities.
