These cheap $100- Valeo knock offs work just fine - I have 100,000 km on mine and is is still perfect.
The cheap Motobatt Oddessy copy works at least as well as the Oddessy too, 3 years / 100,000km and still perfect.
The only test I have seen of the new technology batteries had the Antigravity a long way in front, but that was a few months back and things will probably be changing with the others pretty quickly - you cant keep selling batteries that explode under full load !
