Microtex OPzS

Made in India with


Microtex Advanced Calcium OPzS 2v batteries with high power density are available for Power Generation, Hydroelectricity, Nuclear Power Stations, Solar Energy, Offshore oil rigs, Petrochemical complexes in transparent SAN containers from 100Ah to 3000Ah. Microtex has been manufacturing OPzS batteries since 2007 for standby battery applications meeting European norms.

Innovative Design

  • Transparent SAN (Styrene Acrylonitrile)  containers for visual confirmation of state of battery condition, so essential to mission critical applications like in nuclear power generation industry
  • High impact ABS cover with large polarity indication enhances cell safety and bright colours for easy visual of terminal polarity
  • Designer lead alloys with specially formulated additives like, aluminium, calcium, tin, copper, for positive plates & negative plates to prevent premature failures due to corrosion 
  • Special design provides better & faster conductivity to the terminals minimising internal resistance losses
  • Calcium Lead grids reduce the need to top up considerably
  • Hardened lead alloy with copper insert terminal posts – provide faster conductivity and fail proof connections requiring less maintenance
  • Correctly Balanced Active Materials ensure long life & trouble free performance
  • 150 bar High Pressure Die casted Spine Grids for Tubular Positive Plates (densely compacted under such high pressures prevent early corrosion failures)
  • Superior Woven Tubular Gauntlets (not NONWovens) for Tubular plates Woven tubular gauntlets will not rupture in service and  active material will not leak causing internal shorts & failure
  • Specially designed Ceramic Vent Plugs with high quality ceramic water trap to retain water which may naturally escape from the vented cell 
  • In addition they have explosion inhibiting properties. In very large battery installations, hydrogen & oxygen gases are developed in the overcharge phase creating highly explosive gases which could escape from the cell. In case of spark from outside the cell, the flame will be arrested by the porous ceramic.
  • It is normal for the plates to grow on both sides, vertical & horizontal during the service life of the battery usually occurring noticeably towards the 7th year of service. To accommodate this growth Microtex have designed a unique (Patent applied for), Smart Terminal pole bushing with rubber grommets,  and allows for movement upwards without causing breakage to the cover, which is a common mode of failure in these type of batteries (without this unique feature).
  • Batteries are supplied with factory pre-formed plates. This ensure for reliable performance and no excess cycling required in the field to obtain rated capacity. Saves time for critical users.
  • High quality copper inter cell connectors with accurate current rating design
  • Batteries supplied with floor Stands that are Seismically tested & qualified by certified test houses, stands with special acid proof coating.

Benefits for you

  • Complete range available meeting international sizes
  • Long service life – 20 years designed life – best return on investment cost
  • High performance battery with deep discharge characteristics recovers from deep cycles quickly
  • Low water consumption – less frequent maintenance
  • All India service network

What are OPzS batteries?

OPzS are standby batteries and is generally used to refer Tubular lead Acid Batteries in Transparent SAN containers. These batteries have a cell voltage of  2 volts and connected together to obtain higher voltages, usually used in Power Generating Stations & Substation, Oil & Gas, Nuclear Facilities, Solar and Standby applications.

Trust Microtex, when you need a failsafe battery bank

On an interesting note… OPzS Definition is derived and stands for  O – Ortsfest in German means Stationary Pz – PanzerPlate means Tubular plate (for sturdy and robust) S – Stands for Flussig or Flooded
