Electrolyzer (IndustrialCraft 2)

The Electrolyzer is a machine in IndustrialCraft 2 that acts as added EU storage for the BatBox, CESU, MFE, and MFSU. It stores energy in Water Cells by converting them into Electrolyzed Water Cells.

Recipe
The Electrolyzer is created with four Copper Cables, two Empty Cells, one Electronic Circuit, and one Basic Machine Casing:

Usage
The left slot in the Electrolyzer GUI is the Water slot; Water Cells that are being electrolyzed go there. The left slot in the GUI is the Electrolyzed Water slot; Electrolyzed Water Cells will be placed there upon completion. When an Electrolyzed Cell is discharged back into the energy storage Block, it will be pulled from the Electrolyzed Water Slot, and the Water Cell will be placed back in the Water slot.

When used in conjunction with Buildcraft Transport Pipes or RedPower 2 Pneumatic Tubes, any Water Cells for the input slot needs to come from the top or sides of the Electrolyzer, while anything for the Electrolyzed Water Cell slot should come from the bottom.

The Electrolyzer must be placed adjacent to an energy storage block: either a BatBox, CESU, MFE, or MFSU. GregTech energy storage blocks cannot be used with the Electrolyzer. The Electrolyzer will draw 20,000 EU's from the energy storage block for each Water Cell electrolyzed. The operation is not 100% efficient; each storage block loses a certain amount of EU per transfer, except from the MFSU which is 100% efficient apparently. The primary purpose of the Electrolyzer is added energy storage; this can be useful when the connected power source is not constant, such as in the case of a Nuclear Reactor. When power is coming in, the Water Cells are charged with energy; when the storage block is reduced to 25% of its maximum energy, it will drain energy from the Electrolyzed Cells and store it in the block. The now de-energized Water Cells are put back in the Water slot, and will be charged again when power is available.
