It is permissible to allow sufficient open-circuit rest time after the completion of discharge at cycle 50, •
so as to start cycle 51 at an exact two-week internal. A similar procedure may be adopted at cycles 100,
150, 200, 250, 300, 350, 400 and 450.
If cell discharge voltage drops below 1.0 V/cell, discharge may be discontinued.•
