Re: Costco 6V GC Batteries (Johnson Control): Opinions??
I had Trojan T-125's in my car and just this year replaced them with these CG-2's from Sams(210 Ah). Mine are made by Interstate Battery, their logo is on the label, although small, it is there. I haven't noticed any power difference between the Trojan and these batteries thus far. I also have the same mileage with these batteries. I've just passed 1,000 miles so far. So they are still pretty new and only time will tell but I've not had any issues thus far. I use my car as a daily driver. As for the warranty it is 6 months, but I checked with my Trojan seller and they told me that Trojans also only have a 6 month warranty. So you might check with your seller of Trojans to verify the warranty time. I only paid $66 a piece (times 20 for 120 volt pack) for these, and that is under 1/2 of what I could buy the Trojans for (at the time they were $140). The way I see it, if they last 1/2 as long as Trojans, I am breaking even, if they last longer than 1/2 the time, then I am ahead. I am figuring this will be the last lead pack I buy for the car, hope in a few years new battery technology will be that much cheaper.
