For my money I just fitted a glass matt battery in my R1200GS.
I guess trying to start the bike would warm the battery pretty quickly even although it would most likely fail to start. It's the leap of faith it takes to realise that despite the sound your not actually flattening the battery.
I think the more I read comments the more I want to keep away from these batteries. I don't think they are particularly an incendiary device waiting to happen but their performance does seem to be a bit poor under certain circumstances. Maybe they aren't so bad but the manufacturers are miss representing their true capacity. Certainly seems the case when you have to go up 3 sizes nearly doubling the claimed capacity to get reliable cold starts.
