I just picked up a pair of Duracell GC2 230AH batteries, with a March date code. Brought them home, hooked them up to the Vector and it didn't take long (an hour or so) for the Vector to say "full". Like Ken, my Friese (sp) hygrometer was just at the "green" 1.2ish mark..... Ok I did one full equalization, went up a bit, but definitely low from what I got with Trojan's. So I've got them going through another equalization cycle. Equalization cycle current was 4.1A and Max voltage was 15.7. Still hoping I can get them to 1.275 temp compensated.
BTW the Duracells were replacing a pair of Trojan T-125's that had been abused on a regular basis but finally gave up the gost 1 month shy if 12 years. 5 of the cells still had a good SG, but one cell was dead, dead, dead with SG near 1.0
Trojan's were on my list but at over double the cost of a duracell or Deka, and 3.5X a costco Interstate, they went out of the choice quickly.
