Spent small batteries were disintegrated and leached at 25-65 degrees C for 120 mm with aq. soln. of H2SO4 to recover K, Na, Mn and Zn. The degree of Zn recovery was very low (0.42% at 25 degrees C). No recovery of Mn was achieved. The degrees of K and Na recovery were 92% and 96%, resp., after 120 mm independently on the temp.
