The active materials are encapsulated between folded steel strips, which are perforated on both sides, thereby increasing the effective surface area and making battery more efficient. These batteries use a special separator, which allows gases generated during charging to recombine inside the cell thus ensuring minimal water loss. This concept enables the batteries exceeding the gas recombination requirements defined in IEC 62259. In normal conditions, VentPro battery shall have only one topping up with water in its total service life.

The VentPro batteries are available in tough, shock resistant, fusion welded polypropylene cell containers and lids.

HBL's VentPro batteries are supplied with electrolyte, inter-cell connectors, related hardware and accessories required for normal operation and maintenance. Steel racks can also be offered along with batteries.

Superior Features :

  • Proven pocket plate reliability with lifetime of >20 years and high resistance to failure.
  • Special fiber separator to improve recombination and reduce water consumption.
  • Proven pocket plate reliability with lifetime of >20 years and high resistance to failure.
  • Special fiber separator to improve recombination and reduce water consumption.
  • VentPro's controlled recombination rates eliminate risk of thermal runaway.





  • Specially designed low pressure vent caps.
  • Batteries conform to IEC 62259 standard.


  • The VentPro batteries are available in a choice of plate types, which are designed specially for applications.
  • L type cells : 15 Ah to 1680 Ah.
  • For low discharge rate applications between 3 hours to 100 hours.

  Triumph - Tubular Gel VRLA Battery

Triumph - Tubular Gel VRLA battery offered by HBL is a thoroughly proven product, designed to meet the demanding needs of many diverse applications. These batteries are technologically advanced and are ideal for regular cycling and deep discharge requirements of Telecom BTS sites. These batteries offer excellent cycle life (much higher than Flat plate AGM VRLA batteries) and good performance under partial state of charge operation. Tubular Gel VRLA batteries are highly suitable for telecom BTS sites having unreliable grid power or sites without grid power.

These batteries are maintenance free and do not require a temperature controlled environment. This allows the network operator to save significantly on energy costs (OPEX) that will be incurred in cooling a network site. These batteries also offer a faster recharge capability to save on diesel generator running time after deep discharge cycles - further cutting down on fuel cost (OPEX) and thus lowering the payback period.

These batteries are tested and certified as per IEC 60896-21&22:2004 and IEC 61427-2005.

Superior Features

  • Tubular positive plates - proven cycling and deep cycling capabilities.
  • Gelled electrolyte - no stratification and no failure due to PSOC, better heat dissipation.
  • Valve regulated - no water top up during service life.
  • Antimony free alloy - longer shelf life because of very low self discharge.
  • High pressure die cast spine grids - rate of grid corrosion is very low & hence higher float life.
  • Supplied in filled and charged condition - 100% capacity on first discharge.
  • Versatile in mounting - can be mounted both in horizontal and vertical orientation.
  • Seismic UBC zone IV certified Steel Racks (Up on request for specific layouts).
