Talk:Nickel-Iron Battery

Did some googling around and making notes, here is what I found :

-apprently their efficiency goes *up* with time over about 2 years 80% as mentioned in the forum, unknown exactly why would be nice to know -see the docs from the manufacturer's of the modern batteries seems like efficiency is reasonably high actually, was not able to determine if the charging efficiency is nearly equal to the round trip efficiency, so the graphs might paint an overly rosy picture, but I think it is pretty close http://www.changhongbatteries.com/Ni-Fe_battery_for_Solar_&_wind_appliances_p53_m2.2.1.html

This is good stuff, but it shouldn't be on the talk page, it should be in something like Nickel-Iron Batter/Research. - Mark Norton
