Pure Lead Tin Valve Regulated Lead Acid Batteries (PLT-VRLA)
The PLT or "Pure Lead Tin" technology is an advanced lead acid technology ideally suited to high rate discharge applications where TOTAL reliability is demanded.
Pure Lead-Tin technology offers many advantages which include: High overall efficiency, High energy density, Excellent high rate performance, Excellent low temperature performance, Long float life and High cycle life.

PLT batteries are the ideal choice for: UPS Systems, Engine Starting , Telecommunications, Railway Signalling, Solar Photovoltaic, Emergency Lighting etc.

These Valve Regulated Lead Acid (VRLA) batteries are designed using Absorbent Glass Mat (AGM) separators that render the batteries spill-proof. Use of AGM separators in combination with self-resealing, pressure regulating valves and a starved electrolyte design eliminates the need for electrolyte top-up. PLT batteries are delivered fully charged and can be commissioned immediately without delay.
Tubular Gel Valve Regulated Lead Acid Batteries (T-GEL)
These batteries are of a technologically advanced type and are ideal for regular cycling and deep discharge requirements. These batteries offer excellent cycle life (much higher than VRLA-AGM batteries) and good performance under partial state of charge operation. Tubular gel batteries are highly suitable for power starved areas with unreliable utility sources or sites without grid power.
Applications:
Telecom Base Transceiver Station (BTS) and Base Switches (BSC), Data Center, Solar Photo Voltaic Applications Offshore Platforms, Hybrid Power Systems, Navigational Aids, SCADA Systems, UPS, Switchgear
Superior Features & Benefits:
  • 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.
Other General Purpose Battery Technologies:
Tubular Plate Vented Batteries & Flat Plate AGM VRLA Batteries
These are the advanced Tubular battery technology available with Tubular Positive Plate design suitable for Deep Cycle, partial state of charge and high rate applications. These batteries work on the gas recombination principle.
Also the range covers 2V Industrial batteries called OPzS type robust Tubular battery for standby and deep cycling applications.

Applications:

UPS / Inverter back Up, Solar PV , Industrial Batteries, Transmission & Distribution Substations Power Generation Plants, Switchgear Operation, Signalling & Telecom, Process Control Systems Medical Instruments, Fire & Security Alarm Systems

ALSO AVAILABLE ARE : Silver Zinc and Lithium Thermal Batteries
