It restores the fixture's ability to power its lamp load during mains failure events. Voltage and capacity match the OEM specification for OVA58994.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExiway series compatibility:\u003c\/strong\u003e\n    The Exiway Class, Plus, and One share the same 4.8V battery bay geometry, connector pinout, and charge controller float voltage — so one cell format serves all three variants without modification.\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 simulated mains-fail activation. The BMS accepted the charge without fault flags, and the cell held voltage under lamp load through the full test duration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation test cycle:\u003c\/strong\u003e\n    Within 24 hours of fitting, hold the test button for the full rated duration. This confirms the cell accepts load and lets the charge controller register the new capacity 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\"\u003eA freshly installed Ni-Cd cell that has been in storage for several months will sit below the charge controller's float acceptance window — typically under 5.4V for a fully charged 4.8V Ni-Cd pack. The Exiway charge controller interprets this as a fault state and holds the red LED. Leave the fitting powered on mains for 24 hours. Once the cell climbs above the acceptance threshold, the controller transitions to green automatically.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light dims or cuts out partway through a duration test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when a new cell is tested before it has completed its first full conditioning charge. Ni-Cd cells do not reach rated capacity on the first cycle out of storage — internal resistance is elevated and voltage sags under load sooner than expected. The fix is straightforward: charge the cell on mains for a full 24-hour period before running any duration test. After one complete charge-discharge cycle, the cell stabilises and the fixture should hold lamp voltage above the 4.0V cutoff for the full rated duration.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360424427610,"sku":"BWCS-SVA994LS-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360424460378,"sku":"BWCS-SVA994LS-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360424493146,"sku":"BWCS-SVA994LS-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVA994LS-1.webp?v=1778614656","url":"https:\/\/batteryweb.com\/products\/schneider-exiway-class-replacement-battery-48v-4000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
