Cranking Behavior Observation at Different Temperatures of Sealed Maintenance Free Automotive Lead Acid Battery

Automotive Lead Acid batteries are mainly used to supply high cranking current to start mechanical engines or generators. In this paper, performance of NS60L (JIS Type 46B24L) 45AH Automotive Sealed Maintenance Free (SMF) Lead Acid batteries with specific manufacturing process have been studied through different tests such as Cold Cranking Ampere, Resistivity, Conductivity, High Rate Discharge. All tests were conducted between temperatures 26°C to -15°C. Additional tests such as Capacity, Life Cycle, Porosity tests were conducted to examine plate quality and battery life. Finally, test database has been examined and quantitatively summarized to find out cranking characteristics for SMF battery with particular manufacturing parameters.
