It sits inside the fitting and holds the charge that powers the lamps when mains power drops. Dimensions are 234.00 x 51.30 x 27.00mm — confirm these against your fitting before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFullham FHSBATT8-C3L-SD fixtures:\u003c\/strong\u003e\n    These fittings run a trickle-charge circuit matched to Ni-Cd voltage characteristics. The 9-cell, 9.6V configuration keeps the charge controller operating within its acceptance window and preserves the mains-fail activation response that compliance testing relies on.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran a full discharge-charge cycle on this cell and confirmed the BMS accepted charge from a cold storage state. Load voltage held stable across the test duration without premature cutoff, and the charge controller advanced to float as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-installation test cycle:\u003c\/strong\u003e\n    Within 24 hours of fitting this battery, hold the test button for the full rated duration. A fresh cell shipped from storage may not reach rated capacity on its first activation — one complete test cycle lets the charge controller register the new cell before your next scheduled compliance inspection.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light failing its duration test after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-Cd cell arrives partially discharged after time in storage. The charge controller in Fullham fittings uses a trickle-charge rate that takes 24 hours or more to bring the cell to full capacity. If you run a compliance duration test immediately after installation, the cell will not deliver its full 3000mAh and the fitting will dim or cut out before the rated period ends. Allow a full 24-hour charge before conducting any duration test, then run one complete manual test cycle to condition the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator staying red after new battery installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe charge controller measures incoming cell voltage before switching from fault or charge mode to float. A cell that has self-discharged below roughly 9.0V during storage sits outside the controller's normal float acceptance window, so the indicator stays red even after a confirmed good installation. Leave the fitting on mains power for a full charge cycle — usually 24 hours — without triggering the test button. Once cell voltage climbs into the acceptance band, the controller will shift to float and the indicator will move to green.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360365117530,"sku":"BWCS-FHS830LS-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360365150298,"sku":"BWCS-FHS830LS-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360365183066,"sku":"BWCS-FHS830LS-3","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FHS830LS-1.webp?v=1778611161","url":"https:\/\/batteryweb.com\/products\/fullham-fhsbatt8-c3l-sd-replacement-battery-96v-3000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
