The designated pliot cell voltage is greater than or equal-to 2.0 volts and The overalI battery voltage is greater c.
than or equal to 120 volts (Diesel battery; 112 voits).
The pilot cell sp,F, d.
ecliic gravity, corrected to.77 is greater than or equal to 1.190.
2.
Quarter 1y SurveliIance wIII be performed to verify the followlog:
