Definition of engine starting VRLA battery separator
Tensile strength.
For automatic battery assembly lines, MD(machine direction)tensile strength is very important factor. Tensile strength of VRLA Battery Separator stands for the mechanical strength, using more coarse glass fiber contributes to increase tensile strength.
