The battery delivers consistent 3.2V nominal voltage across its discharge cycle, providing reliable power for emergency luminaires during mains failure.\u003c\/p\u003e\n\u003cp\u003eDesigned for installation in Duceri emergency lighting fittings, the battery fits units configured for LiFePO4 cells and replaces the original battery when capacity degrades after repeated charge-discharge cycles. The pre-fitted wire leads terminate in a standard connector that mates directly with Duceri emergency driver boards, allowing replacement without soldering or terminal crimping.\u003c\/p\u003e\n\u003cp\u003eLiFePO4 chemistry offers longer cycle life and better thermal stability than older NiCd or NiMH emergency lighting batteries, making it suitable for applications where the battery charges continuously on mains power and discharges only during periodic testing or actual mains failures. The 6000mAh capacity supports typical 3-hour emergency lighting durations required under UK building regulations for non-domestic premises. The battery weighs 155g and measures approximately 32mm diameter by 70mm length in cylindrical form.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.155\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.155\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e14.88\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e320\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e330\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e175\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_D002_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_D002.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhich Duceri emergency lights does this battery fit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis battery is compatible with Duceri emergency lighting units specified for LiFePO4 chemistry. Check the existing battery label or the emergency light datasheet to confirm compatibility before ordering. The pre-fitted connector is designed to mate with Duceri driver boards.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does a LiFePO4 emergency battery last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLiFePO4 batteries typically provide 500-1000 charge-discharge cycles before capacity drops to 80% of the rated 6000mAh. In emergency lighting applications where the battery is maintained on trickle charge and discharged only during testing or actual power failures, this translates to approximately 4-6 years of service life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I replace a NiCd or NiMH battery with this LiFePO4 cell?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. LiFePO4 batteries require different charging voltages and current profiles than NiCd or NiMH cells. Only replace with this battery if the emergency light driver board is designed for LiFePO4 chemistry. Mixing chemistries can damage the driver or create a fire risk.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the battery installed?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInstallation requires isolating mains power to the emergency light, removing the old battery by disconnecting the plug connector, and connecting the new battery. The emergency light should then be restored to mains power and tested according to the manufacturer's instructions. If you are not a qualified electrician, arrange for a competent person to perform the replacement.\u003c\/p\u003e","brand":"ESP","offers":[{"title":"Default Title","offer_id":45294092157195,"sku":"D002","price":14.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/D002_38d2cdf7-b27c-4329-b3a7-15a9c2b8cf4f.jpg?v=1714667984","url":"https:\/\/niori.co.uk\/products\/duceri-lifepo4-rechargeable-battery-3-2v-6000mah-emergency-lighting-replacement","provider":"Niori","version":"1.0","type":"link"}
