Clockman, it's the same here (in Canada). We sell Rolls batteries, and it's been a bear to get/keep supply on the shelves. Their 5000-series is not too bad, 6 - 8 weeks lead-time, but their most popular 4000-series one (S-550, or S6 L16-HC as it's called now) is about 3 - 5 months between orders and actually getting them. We stagger orders with Rolls, so we have something coming every couple months. It's been rough though.
By the way, it's not just Rolls, Trojan has the same long lead-times.
