The battery provides backup power to maintain illumination during mains failure, with a 1500mAh capacity supporting typical emergency lighting duty cycles of 3 hours at reduced output.\u003c\/p\u003e\n\u003cp\u003eNickel-cadmium chemistry delivers reliable charge retention and cycle life in emergency lighting applications where the battery remains on trickle charge for extended periods and only discharges during power cuts or testing. The battery measures 200mm long by 90mm wide by 45mm high and weighs 180g, fitting the standard battery compartment in Duceri emergency lighting fittings without modification.\u003c\/p\u003e\n\u003cp\u003eThe battery arrives pre-wired with a white connector plug that mates directly with the Duceri emergency lighting driver board. The assembly date is printed on the battery sleeve — batteries manufactured in 2017 as shown may still function but will have reduced capacity compared to when new. Nickel-cadmium batteries degrade over time even when unused, so check the assembly date before purchase if full rated capacity is required. The CE marking confirms compliance with EU low voltage and electromagnetic compatibility directives.\u003c\/p\u003e\n\u003cp\u003eEmergency lighting regulations in the UK require batteries to be tested monthly and replaced when they no longer hold sufficient charge to maintain illumination for the required duration. Most nickel-cadmium emergency lighting batteries need replacement every 4-5 years depending on usage patterns and ambient temperature.\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\u003e0.18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e14.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e90\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e220\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e385\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e250\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_EMBAT3.6V1500SER_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does this battery last in emergency mode?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 1500mAh capacity typically supports 3 hours of emergency illumination at reduced output in Duceri emergency LED fittings.
