Abstract
A plastic battery container for a recombinant sealed lead-acid battery having reduced end wall deflection, the end wall comprising a base portion from which extends a series of integrally molded ribs disposed at approximately +/−45° to the horizontal, substantially all intersection points of the ribs with the base portion having a rounded character to enhance processing characteristics.
Claims18
A plastic container for a recombinant sealed lead acid battery having a series of cells for containing the electrochemical components of the battery, the cells being separated by partitions having ends, the container further having two side walls disposed adjacent the ends of the partitions, and two end walls each disposed adjacent a respective cell, at least one of said end walls comprising a base portion and a series of ribs disposed at angle on the order of +/−45° to the horizontal, said ribs being integrally molded with said base portion, whereby the ribs function to minimize deflection of said end wall during battery usage, said ribs having a crest and sides, said sides approaching the base portion at an edge, said edge being rounded.
The container of claim 3 comprising at least four ribs disposed on the order of +45° to the horizontal and at least four ribs disposed on the order of −45° to the horizontal.
