Electrodes

The electrodes of OGI batteries consist of positive and negative flat grid plates. the use of positive and negative flat grid plates. The use of the hard lead alloys with an antimony content of less then 2% gives the grids good mechanical strength and corrosion resistance and reduced maintenance due to less water decomposition during stand by and charging operation.

Miccroporous plastic separators are used to separate electrical resistance while permitting good diffusion of the acid and protects against material growth on the electrodes. The separators overlap the plates on all sides thus preventing mossing and resultant short circuits.

the pole bushing are gas- tight to avoid any electrolyte leakage throughout the battery's entire service life and fulfill the requirements under DIN 40729.

the OGI cells are connected to each other by fully insulated screwed (bolted on) connectors. the connectors are made of high quality insulated copper cables up to 120mm dimeter. Lead plated electrolytic copper bar connectors may and can be provided on request.

The electrolyte comprises diluted sulfuric acid with a rated density of 1.220.01 Kg/1 at 20*c. The cells are being delved filled and charged.

The battery containers are made of transparent SAN plastic which makes it easy to check the electrolyte level. Container and lid bonded together to prevent gas and electrolyte escaping.

OGI batteries are always supplied with labyrinth vent plugs. These prevent the escape of electrolyte droplets. Ceramic and or Aqua Gen vent plugs can be supplied on request.

Basically when using Aqua Gen vent the ventilation requirements of DIN VDE 0510 part 2 may be reduced, and maintenance intervals prolonged. The optional vent plugs comply with the DIN 40740 requirement.

- tried and tested for over 20 years
- High endurance at peak current
- Long service life in stand-by operation
- Corrosion resistant pole bushing
- Easy assembly of batteries

Other available equipment and service

Racks made of wood of steel for normal or seismic applications can be provided, as well as design and installation of batteries, in battery rooms and after sales customer support are available.

In practice constant voltage charging has become generally accepted
for continous battery power supply. Using this method of charging' the batteriy can be charged at either 2.23V/cell or 2.4 V/cell for quick recharging followed by awitch to 2.23V/cell. A complete recharge is also possible at a voltage of 2.23 V/cell. A charging current limitation is not necessary up to a charging voltage of 2.4 V/cell. The battery room ventilation corresponds to EN 50 277-2/DIN VDE 0510 part 2.
above ventilation requirements may be reduced when using Aqua Gen plugs.
