yogi singh on 23 Oct 12For the record, the ONLY difference between Procell and Coppertops is packaging and marketing. They are the same battery otherwise, spec for spec, graph per graph... look them up. Procell batteries are aimed at "professionals" who don't need retail packaging. Only Coppertops come in blister packs that can be hung on store shelves.
