Thin Plate Pure Lead Technology
Thin Plate Pure Lead (TPPL) technology takes the benefits of AGM batteries a step further with pure lead electrode plates that can be made thinner than standard AGM engineering so that more plates will fit than in a comparably sized conventional lead acid battery. The additional plates provide as much as 15 percent greater surface area, increasing the electrochemical reactions with the electrolyte. The result is significantly higher cranking power.
