A GC2 battery is 6V and typically over 200 Ah (the common Trojan T-105s are 225 Ah, but current Interstate/Costco ones are labeled 160, which is the low end).
Where did you pick up that information ? Everything I have read is that the Interstate/Costco GC2 batteries are 225Ah.
I ended up finding some "black box" Trojans from Magnacharge (they're a Trojan master distributor), rated for 220 Ah, for $100 each. I've seen the Costco ones (in the past) reported to be 208 or 210.
edit: I wish I had taken a picture. The pictures I find on the web show (varies a bit) 107 RC / 210 Ah. But that doesn't make sense - Ah should be less than RC. A Trojan T-105 is 225 Ah, and 447 RC.
edit: OK, stopped by Costco for gas and to check the batteries. They were out of the GC2s, but still had GC8s (8 volt). Those are marked 160 Ah on the battery. Nothing on the shelf tag for either. Maybe they messed up when they had a bunch of GC2s in the spring.
