Citation needed, because Costco sells Interstate, and are reportedly made by Deka (too lazy to find that reference). The specs don't match the T-105s.
The Internet rumor is that Interstate GC2 batteries ARE Trojan T105s. Interstate markets SEVERAL different GC2 batteries and I do not know which model is sold through Costco. T105s are speced at 447 minutes @ 25A and 225AH @ 20 Hrs. Very few batteries are going to match these specs.
Deka batteries are made by East Penn Manufacturing. East Penn DOES make Duracell lead acid batteries.
