Abstract :
This paper is based on a joint study conducted by Lucent Technologies and Sprint Florida on monitoring the state of health of valve-regulated Pb-acid (VRLA) batteries. The purpose of the study was to see whether ohmic techniques (impedance, resistance and conductance) can accurately predict the state of charge and state of health of the batteries. This study consisted of field testing as well as accelerated laboratory testing. Comparison of the commercial meters and recommendations on minimizing the measurement errors have also been made
