The 15 kW battery, or electric accumulator, is an object removed from the final version of Alone in the Dark: The New Nightmare.
Features[]
In the game files, the 3D battery model is described as an electric accumulator built by Jeremy Morton. It's unclear how it should act, however it should have been used to reload weapons that use light. It is likely that initially the Luminescent Crystals present in the World of Darkness had to be collected and combined with the accumulator so as to obtain the energy necessary to operate Jeremy Morton's weapons, the process may have been discarded because it was unnecessarily artificial.
