I can testify to that! The Optima Spira-Cell has lasted three times as
long as any other battery I have used in my Passat TDI TurboDiesel.
The constant severe diesel vibration and the very high cranking currents
required to start the diesel just kills most batteries. It also seems
to tolerate the occaisional deep discharge from leaving radio gear on
better than other batteries.
