VRLA - PPST & UPST Range Batteries

Exide VRLA Batteries
Exide Power safe VRLA Batteries have been developed by Exide R&D center, in close collaboration with Shin Kobe Electric Machinery Co. Ltd., Japan, the manufacturers of Hitachi batteries, and are suitable for stationary applications in Indian conditions. The overall battery package is essentially directed towards attending to the inevitable rigorous environmental factors under which batteries are expected to perform in India. These include prolonged elevated temperature operation, frequent charge/ discharge cycles and occasionally deep discharges.
Power safe Batteries use a proprietary composition of lead calcium and tin alloy for the positive grid. Alloys based on calcium are inherently of low float current characteristics. The grid alloy per se leads to low float current and hence low water loss and oxygen recombination. This inherently means that heat evolution in lead Calcium system is low. This, together with better thermal management, allows the Exide VRLA batteries to perform better in extreme temperatures.
Features

• Sealed Maintenance-Free VRLA
• Less than 0.5% weekly self-discharge
• Eco-friendly and ready to use
• Cadmium-free
• Flame arrestor safety valve
• Low footprint

2V VRLA PPST Range
EXIDE has developed new PPST range for 20 years float design life in close collaboration wih Hitachi Chemical Japan & East Penn Technology - USA. It is most suitable for long life stationary application in Indian condition. It is a completely new range with robust grid design for long life application & multiple terminal designs to withstand high current application
Salient features of PPST range

• Sealed Maintenance-Free VRLA
• Robust grid design for long float life application
• Special Ca- Tin corrosion alloy to minimise the corrosion rate during its entire service life
• More compact design
• Ribbed container to prevent the bulge & better thermal management
• Multiple terminal design to reduce the voltage drop & improve the current carrying capacity
• Lower footprint

Feature of PPST Range

• Superior Performance
• Low Self Discharge (Less Than 0.5% Per Week) which allows the battery to be stored for 3-6 months depending on ambient temperature
• Excellent recovery from deep discharge
• Enhanced plate length for high power density
• 4/6 Terminal design in higher capacity range to reduce the voltage drops
• Sealed Maintenance Free having more plate surface area which is suitable for high current flow

Safety

• Ribbed container design for better thermal management in the system.
• Self-resealing flame arrestor fitted safety valve.
• Resistant o thermal runaway due to calcium tin alloy
• Low footprint

Life

• Service life comparable with the best of the international makes

• Design life is 20 years at 27under ideal float condition
  
  • 4000 cycles at 20% DOD
  • 1800 cycles at 50% DOD
  • 1400 cycles at 70% DOD

Low Self Discharge
Antimony free alloy and hence self-discharge less than 0.5% per week at C10 capacity at 27
Low self-discharge allows the battery to be stored for 3-6 months depending on the ambient temperature and with occasional freshening charges, there is no subsequent loss of performance
Performance Conforming to

• IS 15549:2005
• JIS: C 8704 - 2:1999
• IEC: 60896 -21&22
• ANSI: T1 330 (US specification for Telecom battery)
• RDSO: IRS S93-96 with latest amendments
