Well first off I am new to this forum and would like to say Hi and also a big thank you for this great resource of information. Over the past few days I have read tons of reading material on wind turbines and my knowledge is growing, but some information I still am in need of clarification. I been pondering the thought of using a WN 750 to charge a 24V battery bank. But this is where information seems to be thin or maybe I just haven't been able to find the right resource yet. What I would like to know is how fast can one charge a battery bank of any type of battery. The three types that seem reasonable to me are the typical auto pb-acid, deep cycle, and gel. Now I don't know a whole bunch about batteries, so if anyone can explain to me the difference or point me to a good an reliable resource it would be appreciated. Is it possible to charge any of these types of batteries at the max output of the 750 in 35 mph wind at 40+A of current? What dangers am I looking at if I was to charge these faster then they should normally be( I only ask this because I read somewhere that pb-acid needed to be slowly charged over a three step process. How true is this information, can I trust it)? If you can't charge these at the high amperes then what benefit would the 750 actually do over say the 500? I guess my biggest and single most important question is will I be wasting any power that is generated while my batteries are charging? Sorry if this sounds dumb... But I am just the type of person that needs to understand all aspects of the process that I intend to waste my time on.
