Forever? Well, at least Edison thought they should last 100 years. As mentioned
by others, inefficiency is an impairing factor in an RE system. However, due to
the all time low cost for PV solar modules, these batteries can actually be a
viable option. If you have the space for 40% more PV
I have 5,000 pounds of original Edison
NiFe batteries, made between 1928 and 1939.
Almost all of them are working at close to 90% of their original
capacity.
I would be willing to bet that Edison was really close with his
100 year estimate.on his

We do discuss NiFe (Edison) battery banks with the students in all our
