It is a Colorado company, but they are importing them from China. I've met the owner. <br>My understanding is the plates do not deteriorate, but the electrolyte needs to be replaced every 5 - 10 years, so technically you would never need another set, just KOH.<br><br>Ray Walters<br><br>On May 5, 2012, at 12:43 PM, Phil Theis wrote:<br><br>> Thanks Bill,<br>> They are presumably making these in Lakewood, CO<br>> <a href="http://ironedison.com/about-us" target="_blank">http://ironedison.com/about-us</a><br>> Phil<br>> <br>> On 5/5/2012 3:32 PM, William Dorsett wrote:<br>>> I don't know that there are any new sources for NiFe batteries and the last<br>>> ones were either from China and Hungary.
