I just saw this battery at the NY motorcycle show .
It looks interesting if their claims are true . It holds a charge even after sitting for a year . Lasts 2 - 4 times as long as a lead acid battery . Not acid to spill . And the 18AH battery only weighs 2 pounds . But not cheap @ something approaching $ 180.
Interested what others thought of this battery and if anyone has actually tried one .
