We now supply a $315 Automatic Gravity Feed Battery Electrolyte Filling System Kit, that provide a maintenance free operating system, this system is made from 6mm Plastic Air line fittings shown below.

NB: The Battery Cells will be automatically Filled to the level you insert the Stainless Steel Tube into the cells, when the Electrolyte Level falls below the Stainless Steel Tube, the Distilled Water will then automatically flow into the battery until it touches the Tube.

A Dangerous situation is created when the Electrolyte level falls below the Nickel Iron Plates in any Cell, as then a Cell can Overheat & Short !

IMPORTANT: An Automatic Distilled Water Tank can be ANY size, and must ONLY Release Distilled Water from a vacuum sealed Tank, the filling Tank must ONLY let Air enter this Tank via the Battery Cell Fill lines, if the Filling Tank is NOT a Vacuum Tank the Distilled Water will simply drain out and over fill the battery cells ! This automatic filling system works on the principle that, Air is Only drawn into the Distilled Filling Water Tank when the Electrolyte in any Cell Drops below any inserted tube, as only then will Air be drawn into the watering tube & bubble back into the Reserve Tank, and then Distilled Water will flow down into the Cell, to the level the Tube is inserted.

NB: The Stainless Steel Filler Tubes should be Drilling & pushed through the filler Cap or Battery Casing, tight enough so not to move, the battery cell should have a Tiny Breathing Hole in the Top of each Cell, this is to let Air in & Out of each Cell, so the System Works correctly !
