Galvanic element
Current source whose electrical energy is released through electrochemical processes.
Gas formation (gassing)
The development of hydrogen and oxygen when overcharging electrochemical cells with hydrous electrolytes.
Gas outlet, central
>> Central gas outlet.
Gauntlet
Put over the positive spine grid and filled with paste or oxide to form the positive tubular plate.
Gel
Electrolyte jellified through the addition of silicic acid to sulphuric acid.
Gel battery
>> Maintenance-free battery with fixed electrolyte.
Glass mat
Thin sheet of glass fibres held in place by means of a bonding agent and placed against a positive plate.
Golf-Car batteries
Special deep cycle batteries, mainly 6V, used as traction battery for Golf-Cars. Biggest market in the U.S.
Grid
A lattice framework that supports the active mass in an electrochemical cell.
Grid casting machine
A machine which casts automatically >> grids from given lead >> alloys. Most of the grid casting machines are of similar design and cast a single
double grid in a vertical positions from a vertically mounted mould. One part of the mould is stationary, the other is moveable on leader pins. The machine
is normally equipped with a trimming die to cut off the sprue.
Grid feeder
Installed at the entrance of a >> pasting machine, takes panels (double grids) or single grids, piece by piece from a stacks and feed the pasting machine.
Two systems are used for picking the grids: mechanical or with vacuum pick up.
Grid growth
Deformation of the frame of positive grid plates resulting from corrosion of the grid lead.
Grid pasting machine
>> Pasting machine
Grid plate
A grid in an electrochemical cell which is pasted with active mass.
Grommet
Seal between the post of an industrial battery cell and the lid.
Grommet setting machine
Automatic machine for setting of rubber made >> grommets in the lids of tractionary battery cells. Can be equipped with manual or automatic grommet feeding magazines.
Group
>> Cell
Group burning machine
Machine for welding together the lugs of >> cells. Only used in low cost countries or for small quantities.
