Battery Room Considerations
To ensure that the ventilation of a battery room is adequate to keep the concentration of hydrogen gas within safe limits, it is necessary to be able to calculate the rate of evolution of hydrogen. Hydrogen is evolved during a recharge or freshening change of a battery when the voltage rises above 2.30 volts per cell.
