This paper is primarily going to report on a sixty-cell VLA (vented lead-acid) stationary battery that failed horribly when called upon during a unit trip.The battery had what would be considered a quality,quarterly,preventative-maintenance (PM) program,which included battery capacity testing.The overall cost from that failure at the power plant resulted in a loss exceeding $8 million.This is not considered to be'chump change'in anyone's book.At the time of the failure (5/26/19) the battery,from a major quality battery manufacturer,was only four years and seven months old.The battery had passed a battery capacity test 14 months prior to the failure.How can this happen?
