Valve Regulated Lead Acid Battery for
Communications Standby Power Applications
In critical standby power applications, maximum battery life is
essential. Dynasty long duration batteries deliver this while complying
with rigorous industry standards. Computer modeling, stringent
components materials selection and design criteria as well as
state-of-the-art automated manufacturing are all validated through
extensive life-cycle testing and years of in-service life in
telecommunications and uninterruptible power systems applications.
- Flame-arresting one-way pressure-relief vent for safety and long life
- Thermally welded case-to-cover bond to ensure a leakproof seal
- Flame-retardant polypropylene case and cover compliant with UL94 V-0 with a Limiting Oxygen Index of greater than 28
- Absorbent Glass Mat (AGM) technology for efficient gas recombination of 99% plus
- Thick positive plate design for maximum service float life - 10 year design life
