Rejuvenation of a NiFe Accumulator from 1930´s
Original language description
A rejuvenation process of a very old nickel-iron accumulator (about 75 years) is described in this article. The supposed nominal parameters of the accumulator are 12V/(8Ah -10Ah). All cells of the accumulator were cleaned and rejuvenated by a quite long and laborious process including 11 cycles of charging and discharging, several changing of the electrolyte and even using a deep discharging to improve the capacity of the negative iron electrode. The charging and discharging characteristics of all cells were measured during the rejuvenation. Finally also the internal resistance of the accumulator was measured. The wooden case, output terminals and all the accumulator accessories were renovated. The work showed a surprising durability of old NiFe accumulators (see below).
