Hi all,

I understand that whenever we charge a battery, hydrogen emission would occur. Are there any gases emitted apart from hydrogen? What is the acceptable level of hydrogen emission? How do I calculate the level/amount of hydrogen gas emitted? I need some guidance on this and would appreciate the assistance from fellow forumers.

With gratitude,
Landon

 

YOu get oxygen liberated with the hydrogen. Since the plates are close together, the gasses mix in an explosive ratio. It is important to limit charging voltage to minimize electrolysis during the charging.
