ALUX OPzS 350Ah 2V Tubular Gel Battery (OPzS350)

ALUX OPzS 350Ah 2V Tubular Gel Battery (OPzS350) is a 2 V 350 Ah tubular gel battery in a 124 × 206 × 471 mm case weighing 20 kg, rated for deep-cycle duty in telecom, UPS and substation standby. Dimensions, terminal type and weight are listed in the specification table.



Product Overview

The ALUX OPzS350 is a 2 V 350 Ah OPzS tubular gel cell, 124 × 206 × 471 mm over the case (512 mm including terminals) and weighs 20 kg. The OPzS range uses thick tubular positive plates for large-capacity, long-duration discharge — utility and substation duty rather than short high-rate bursts. Cells are series-connected into the bank voltage, with 2 M10 × 20 terminals per cell.

Key Features

  • Thick tubular positive plates — a heavy tubular plate design built for large-capacity, long-duration discharge rather than short high-rate bursts.
  • Gel electrolyte — immobilised acid keeps tall cells homogeneous and the battery maintenance-free.
  • High-temperature tolerance — rated for cabinets and shelters at 35–70 °C.
  • Glass-fibre separator — high-absorption separator holds electrolyte against the plates and extends cycle life.
  • High-strength ABS container — moulded case and lid for stationary banks.
  • Bolt terminals — threaded posts, terminal count as listed, for copper connector bars.
