The proper classification of batteries, particularly small industrial batteries used in safety applications such as emergency lightings, Uninterruptable Power Systems (UPS), medical equipment and alarm systems, has to be addressed in a homogeneous and unambiguous
Valve-regulated lead–acid (VRLA) batteries are also referred to as ''recombinant'' batteries. Unlike flooded batteries, which lose water as a result of oxygen and hydrogen evolution at the positive and negative electrodes respectively during charging, in VRLAs, oxygen will recombine with the hydrogen to reform water [ 10 ].

Every battery cell is therefore equipped with a one-way valve. This valve allows excess gases to be vented when required, but does not permit outside air to enter. The presence of these one-way valves therefore gives rise to the correct "Valve-regulated" classification for FIAMM-GS batteries, instead of the more commonly used,

Valve-regulated lead–acid batteries operating under the oxygen cycle have had a major impact on the battery market over the last 25 years. They differ from conventional flooded batteries in that the electrolyte level is controlled to ensure that some gaseous porosity remains in the separator.
Oxygen-recombinant valve-regulated lead-acid (VRLA) batteries [1,2] use the same technology as flooded lead-acid batteries, but the acid electrolyte is immobilised by sealing the battery with a valve. This eliminates the need for addition of water and avoids electrolyte mix preventing stratification.
In this revision, particular reference is made to ‘General Definitions’, ‘Product Characteristics’, ‘Design Life’, ‘Service Life’ and ‘Safety’. A valve regulated cell or battery is closed under normal conditions by a non-return control valve that allows gas to escape if the internal pressure exceeds a predetermined value.
This valve allows excess gases to be vented when required, but does not permit outside air to enter. The presence of these one-way valves therefore gives rise to the correct “Valve-regulated” classification for FIAMM-GS batteries, instead of the more commonly used, but inaccurate, “sealed” classification.
The electrolyte immobilization has formed the basis of classification of the VRLA battery in terms of gel and AGM separators .
