CALCULATED VS. ACTUAL SHORT CIRCUIT CURRENTS FOR VRLA BATTERIES “shorted” lead acid battery has the capability of delivering an extremely high current, 100 to 1000 times the typical discharge current used in most applications. Electrical systems using batteries must be properly protected to avoid potentially dangerous fault conditions.
Failure modes of the valve regulated lead acid battery will not only greatly reduce the service life, but also may start a fire. This paper reviews the relationship between battery fire and failure modes.

B. Culpin, in Encyclopedia of Electrochemical Power Sources, 2009 Valve-regulated lead–acid batteries operating under the oxygen cycle have had a major impact on the battery market over the last 25 years.
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 .
