Where lead-acid external battery packs are bulky, heavy, and subject to capacity degradation within 3–5 years, this lithium-ion XBP delivers high energy density in a compact 2U chassis — and maintains consistent capacity over a battery lifespan of up to 10 years. Up to five units can be cascaded to a single SRTL 5kW UPS, providing the extended runtime buffer needed for data centers, healthcare facilities, and mission-critical edge deployments.\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 (SRTL180RM2UBP)\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\u003eSignificantly heavier per kWh\u003c\/td\u003e\n\u003ctd\u003eUp to 40–50% 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\u003eBMS Monitoring\u003c\/td\u003e\n\u003ctd\u003eLimited or none\u003c\/td\u003e\n\u003ctd\u003eCell-level, module-level, cabinet-level\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 chemistry with embedded BMS — monitors state of charge and battery health continuously\u003c\/li\u003e\n  \u003cli\u003e2U rack\/tower convertible chassis — installs directly with compatible SRTL 5kW rack deployment\u003c\/li\u003e\n  \u003cli\u003eStack up to 5 units per SRTL 5kW UPS for extended runtime to meet site-specific autonomy requirements\u003c\/li\u003e\n  \u003cli\u003e5-year warranty on the battery pack and cells — aligned with SRTL UPS warranty\u003c\/li\u003e\n  \u003cli\u003eHot-swap capable — battery pack replacement without UPS shutdown (when UPS supports it)\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 5kVA\/5kW Smart-UPS Ultra models\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\u003eNominal Voltage\u003c\/td\u003e\n\u003ctd\u003e180V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eForm Factor\u003c\/td\u003e\n\u003ctd\u003e2U Rack\/Tower convertible\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\u003eDimensions (H x W x D)\u003c\/td\u003e\n\u003ctd\u003e86mm x 432mm x 724mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e32.4 kg\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\u003eThe SRTL180RM2UBP is the right XBP for any environment where extended runtime is a mission requirement and frequent battery replacement is operationally unacceptable. Healthcare facilities and imaging centers need runtime buffers that outlast power restoration windows. Colocation facilities and managed service providers running SRTL 5kW UPS systems across multiple racks benefit from the reduced battery replacement cycles and the BMS data that integrates with EcoStruxure IT for centralized fleet management. Remote or edge deployments — manufacturing plants, government facilities, utility substations — where on-site maintenance resources are limited gain the most from the 10-year lithium-ion lifespan.\u003c\/p\u003e\n\n\u003ch3\u003eReduce Battery Maintenance Across Your Fleet\u003c\/h3\u003e\n\u003cp\u003eQuestyme works with organizations managing multiple UPS systems across single or multi-site environments. We help you calculate the runtime you need, determine how many SRTL180RM2UBP units to deploy per UPS, and plan battery replacement schedules that minimize both cost and operational disruption. If you are evaluating total cost of ownership between lead-acid and lithium-ion extended battery deployments, contact Questyme for a TCO analysis tailored to your environment.\u003c\/p\u003e","brand":"APC","offers":[{"title":"Default Title","offer_id":44388613357656,"sku":"SRTL180RM2UBP","price":6021.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/7845\/4872\/files\/SRTL180RM2UBP-A.jpg?v=1784202981","url":"https:\/\/questyme.com\/products\/apc-smart-ups-ultra-li-ion-external-battery-pack-180v-2u-rack-tower-for-srtl-5kva-5kw-systems","provider":"Questyme","version":"1.0","type":"link"}
