I contacted them by email in September of 2021 and they replied at this time they are not refurbishing any batteries. I bought a small set of Iron Edison batteries shortly after and I recently looked at Iron Edison's website and the site looks more geared towards their Lithium Iron brand then their Nickel Iron batteries. That change has been done in the last few months, a sign of the times? I just hope they support electrolyte changes in the future.
