Out-of-battery refers to the status of a weapon before the action has returned to the normal firing position. The term originates from artillery, referring to a gun that fires before it has been pulled back into its firing position in a gun battery.
In firearms and artillery where there is an automatic loading mechanism, a condition can occur in which a live round is at least partially in the firing chamber and capable of being fired, but is not properly secured by the usual mechanism of that particular weapon. The gas pressure produced at the moment of firing can rupture the not fully supported cartridge case and can result in flame and high pressure gas being vented at the breech of the weapon, potentially creating flying shrapnel possibly injuring the operator.
There are many reports of modern pistols being damaged or destroyed by out of battery discharges that has led to the use of the term kB - meaning "kaboom".[1]
