What have we learned over the years?

摘要

1.That PCL can occur with any manufacturer's cells.2.That dry-out with any VRLA battery is the kiss of death.3.Hotter-than-standard environments accelerate dry-out.4.Negative plate self-discharge and under polarisation/charging causes over charging of the positive plates and reduces capacity and life.5.PCL caused by dry-out or negative plate discharge can be reduced/corrected with any structurally-intact cell,once proper saturation has been established.6.All manufacturers have made improvements to their products over the years.7.There is a wide variance in the quality of products from around the globe.8.All'pure'lead is not equal.9.Plate orientation vertical or horizontal(pancake)does not yield any substantial difference in the ability of the cells to recover from PCL.
