[RE-wrenches] battery cycle life, US Battery

[Ray Walters]

Hi James;

I'd like to see the presentation again (I WAS there in 04) Also, I think 
it would be very helpful for a competent manufacturer (like yourselves) 
to comment on how the cycle testing is done, whether you use a 100 hr, 
or 20 hr discharge rate, etc. and also whether battery testing is 
standardized, or do other manufacturers test using different criteria.
Finally have these numbers changed in the past several years, because 
AEE has the wrong cycle life for your 4000 series battery listed in 
their catalog, as did I :) (1000 vs 1280 @ 50% DOD)

Really appreciate your contribution to our knowledge base,

Ray Walters
