Figure 8-1. Ventilation system for battery maintenance facilities.
Hydrogen generated, in cubic feet per hour (cfh).
Float current per 100 ampere-hour. FC varies with battery types,
battery condition, and electrolyte temperature. It will double/halve for
each 15 degrees F (8 degrees C) rise/fall in electrolyte temperature.
A constant of 0.016 cubic feet of hydrogen per 1 ampere-hour per
cell (at sea level and 77 degrees F ambient temperature).
Number of battery cells.
