Accurate estimation of the valve regulated lead-acid (VRLA) batteries ageing, degradation and failure modes are very important for performance maintenance and safe operating conditions. This paper introduces simple but effective techniques that achieve better estimation accuracy. The technique was tested and analyzed by using results obtained from experiments conducted at the YUASA battery laboratories. The results indicated that the positive active material is the major cause for the low discharge performance of the batteries tested. In low performance positive plates tested, in charged condition, 5.52% of lead sulphate was found and that could be limits the active material available to accept current and so bring down the efficiency. Appreciable benefits might be accrued from these results and using this techniques.
