Abstract:
Provided is a battery grid pellet adhesion/cohesion strength tester that can accurately determine the push-out strength of a battery grid pellet by measuring the binding of the active material to the battery grid during the pasting and curing process. A programmable test stand and force gage are used with a selectable active material punching tool fixture and a set of selectable set of grid location pins. Active material from a lead-acid battery is forced out of the battery grid at a programmed feed rate with the force gage reporting precise force measurements for each battery grid pellets adhesion/cohesion strength. The inventive device can be utilized as a quality control measure following the battery pasting and curing process, which will ensure that consistent and uniform adhesion/cohesion has occurred during battery manufacture, thereby avoiding battery premature performance failure.
