It slots into the existing fitting and restores backup illumination capability when mains power fails. OEM part number DS1720-1 identifies this as the correct cell for this fixture.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eJLECE2RW fitting compatibility:\u003c\/strong\u003e\n    The JLECE2RW uses a single 3.6V Ni-MH cell managed by an onboard charge controller that expects a specific charge acceptance curve. This cell matches that voltage rail and chemistry, so the controller recognises it and enters float charge correctly after the initial conditioning cycle.\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 cycle and a load test simulating emergency activation. The BMS accepted the cell without fault, floated at 3.6V, and the charge indicator transitioned from red to green within the expected window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst test cycle after installation:\u003c\/strong\u003e\n    Hold the test button for the full rated duration within 24 hours of fitting this cell. This confirms the cell accepts load under the charge controller and lets the controller register actual capacity before any scheduled compliance test runs against it.\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\"\u003eA freshly fitted cell that has been in storage can arrive with a terminal voltage outside the float acceptance window of the JLECE2RW charge controller. When the controller sees a voltage below its threshold, it holds the charge LED red and continues pushing current rather than entering float. This is normal behaviour — not a fault with the cell or the fitting. Leave the unit on mains power for 24 hours and the LED will shift to green once the cell climbs into the acceptance band above 3.6V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light dims partway through a duration test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the light fades or dims before the rated duration is complete on the first test after replacement, the cell has not yet reached full capacity from storage conditioning. Ni-MH cells need at least one complete charge-then-discharge cycle to deliver rated capacity. Allow the unit to charge for a full 24 hours on mains, then run the test again. A cell that still dims on the second test after full charge may have a connection issue — check the solder tabs or spring contacts are making firm contact at both terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360394215514,"sku":"BWCS-DTX317LS-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360394248282,"sku":"BWCS-DTX317LS-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360394281050,"sku":"BWCS-DTX317LS-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DTX317LS-1.webp?v=1778611141","url":"https:\/\/batteryweb.com\/products\/ifeituo-jlece2rw-replacement-battery-36v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
