I like Peter's response, but here's another idea: recall Nawaz's 
statement that cycle life is reproducible only to +/-25%, so assume 
that you will actually get just 75% of what Dynasty quotes, and then 
factor in a bit more since you can continue to use the batteries 
while their capacity is between 80-40% of rated.

Also bear in mind that no matter how good the batteries are, you 
can't get this life if your charger murders them prematurely.  What 
are the charging requirements of the Dynastys, and can your charger 
satisfy them?

Cheers,

Roger.
