Designed to complement the compact, lightweight form factor of the SRTL 2U rackmount UPS, this 1U battery pack adds meaningful runtime without the weight and bulk of lead-acid alternatives. Up to five units can be cascaded per UPS, giving operators the flexibility to dial in the exact runtime buffer required for their application — from a few minutes of bridge power to extended autonomy during prolonged outages.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Lithium-Ion vs. Lead-Acid External Battery Packs?\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eFactor\u003c\/th\u003e\n\u003cth\u003eLead-Acid XBP\u003c\/th\u003e\n\u003cth\u003eLi-Ion XBP (SRTL50RMBP1U-LI)\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBattery Lifespan\u003c\/td\u003e\n\u003ctd\u003e3–5 years\u003c\/td\u003e\n\u003ctd\u003eUp to 10 years\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eHeavier per kWh stored\u003c\/td\u003e\n\u003ctd\u003eSignificantly lighter\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eRecharge Time\u003c\/td\u003e\n\u003ctd\u003e4–8 hours\u003c\/td\u003e\n\u003ctd\u003eApproximately 3 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eReplacement Cycles (10 years)\u003c\/td\u003e\n\u003ctd\u003e2–3 times\u003c\/td\u003e\n\u003ctd\u003e0–1 times\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eTemperature Tolerance\u003c\/td\u003e\n\u003ctd\u003eNarrow range\u003c\/td\u003e\n\u003ctd\u003eWider operating range\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLithium-ion battery chemistry with up to 3x the lifespan of VRLA lead-acid packs\u003c\/li\u003e\n  \u003cli\u003e1U rack form factor — space-efficient when stacking multiple packs below the UPS\u003c\/li\u003e\n  \u003cli\u003eUp to 5 units per SRTL 2.2kVA or 3kVA UPS for configurable extended runtime\u003c\/li\u003e\n  \u003cli\u003e5-year warranty on battery pack — matches the SRTL UPS warranty period\u003c\/li\u003e\n  \u003cli\u003eCompatible with SRTL 2kVA and 3kVA Smart-UPS Ultra models only — not interchangeable with SRTL 5kW XBP\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCompatible UPS\u003c\/td\u003e\n\u003ctd\u003eSRTL 2.2kVA and 3kVA Smart-UPS Ultra models (SRTL2K2, SRTL3K series)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBattery Type\u003c\/td\u003e\n\u003ctd\u003eLithium-ion\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eForm Factor\u003c\/td\u003e\n\u003ctd\u003e1U Rackmount\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eMax Units Per UPS\u003c\/td\u003e\n\u003ctd\u003e5 (cascaded)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5 years repair or replace\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eIdeal Applications and Industries\u003c\/h3\u003e\n\u003cp\u003eSmall data closets, branch offices, and edge server rooms running SRTL 2.2kVA or 3kVA UPS units benefit from this 1U XBP when runtime requirements exceed the internal battery capacity. Government agencies and healthcare networks running remote site infrastructure particularly value the reduced maintenance burden — fewer battery replacements over the 10-year deployment window translates directly to lower operational cost and fewer service calls to remote locations. Financial services firms with tight rack density constraints also benefit from the 1U form factor when planning extended runtime without sacrificing valuable rack space.\u003c\/p\u003e\n\n\u003ch3\u003eReduce Battery Maintenance Across Your Fleet\u003c\/h3\u003e\n\u003cp\u003eQuestyme helps organizations operating multiple SRTL 2.2kVA and 3kVA UPS systems determine the right number of SRTL50RMBP1U-LI packs per unit to meet their runtime requirements.
