Storage Battery Systems Inc. has designed the "T" Series battery to exceed the stringent requirements of today's cellular & wireless communications environment. All the advantages of the VRLA AGM sealed lead acid design including minimized gassing, lower float currents, extended service life & outstanding performance throughout a large profile of discharge curves are imbued in its construction. The 20 year design life is backed by a warranty & installation is simplified by the integral steel case & standard Zone 4 racking. The T Series reduces jar bulging & facilitates replacement on site. The cases are designed to adapt to slight grid growth to achieve the full design life. Additionally, the brass posts have dual seals & secondary epoxy barriers to prevent any distortion or loss. Cell sizes range from 80 to 2000A/h with multiple cell/case configurations to 5800 A/h. All cells are fully charged at 100% capacity. Optional flame retardant (UL 94 VO)jars & alternatives to the standard "top" terminal plates are available. System line-ups come with Lexan safety shields. The T Series meets all IEC/EN 60896-2, BS6290 Part IV standards & it is classified as "Long-Life" un der EuroBAT g.1999. The T Series is manufactured in 49 capacities so that it can be appropriately sized economically for 24/48v telecom to 480v UPS applications. Additional advantages include a wider operating temperature of -4 F to +131 F. With a self-discharge less than 0.5%/week, the T series is a serious advancement in telecom batteries.
