The role of hydrogen in sealed lead-acid batteries
The lead-acid battery, introduced around the mid-19th century, has gone through many changes as it evolved from the flat lead sheets of Plante to the pasted plates of Faure and Volckmar [1]. It has found widespread industrial use, even as the two world wars brought more interest to this technology.

The three-phase UPS battery handbook
During the charging of a lead-acid battery, hydrogen is normally liberated . In a vented battery, the hydrogen escapes into the atmosphere . In a VRLA battery, the hydrogen recombines with oxygen inside the battery, so water loss is minimized . Under normal float conditions, virtually all the hydrogen and oxygen is recombined .
