It also fits the 117318, 2 HRMT 23\/43, and 2 KMRT 23\/43 fittings. When the original cell degrades, the fitting fails its duration test — this cell restores backup illumination capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e117319, 117318, 2 HRMT 23\/43, 2 KMRT 23\/43 compatibility:\u003c\/strong\u003e\n    These URA fittings share a 2.4V charge rail and the same physical cell format — two sub-C Ni-Cd cells in series. The charge controller float voltage and trickle rate are matched to this chemistry, so no BMS handshake is required beyond cell presence and voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on a 2.4V Ni-Cd charge controller. The cell accepted charge correctly, reached rated terminal voltage, and held load voltage within spec during a simulated duration draw. No premature cutoff was observed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-fit test cycle for emergency compliance:\u003c\/strong\u003e\n    Within 24 hours of installation, hold the fitting's test button for the full rated duration. A freshly installed Ni-Cd cell may not yet be at full capacity from storage — one complete discharge-recharge 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\"\u003eCharge indicator staying red after new battery installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eURA security block fittings use a float-charge controller that checks incoming cell voltage before switching to green. A Ni-Cd cell that has sat in storage for months can drop below the controller's acceptance threshold — typically under 2.0V open circuit. The controller sees this low voltage and holds a fast-charge state, keeping the indicator red. Leave the fitting powered for 12–24 hours; once the cell climbs above roughly 2.2V, the controller will shift to float and the indicator should switch to green.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light dims and cuts short during a duration test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when a new cell has not completed its first full conditioning cycle. Ni-Cd cells shipped from storage deliver reduced capacity on the initial discharge — often 60–70% of rated capacity. The fitting's lamp draws sustained current, and the under-conditioned cell sags early. Run one complete manual test cycle immediately after installation, then allow a full 24-hour recharge before treating the result as a valid compliance test. Rated capacity of 2000mAh is achieved reliably from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360411353178,"sku":"BWCS-MGN761LS-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360411385946,"sku":"BWCS-MGN761LS-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360411418714,"sku":"BWCS-MGN761LS-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MGN761LS-1.webp?v=1778614613","url":"https:\/\/batteryweb.com\/products\/ura-117319-security-block-replacement-battery-24v-2000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
