It slots into the existing fitting and restores the backup power that activates when mains power fails. Dimensions are 237.00 x 32.60 x 32.60mm — confirm clearance before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eB170\/44 fitment:\u003c\/strong\u003e\n    The B170\/44 uses a dedicated Ni-CD cell at 4.8V to match the charge controller's float voltage rail. Swapping to a different chemistry or voltage triggers a persistent fault state on the charge board.\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-drop activation. The BMS accepted charge without error, and the cell held voltage under load through the full rated test duration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst installation test cycle:\u003c\/strong\u003e\n    Within 24 hours of fitting, hold the test button for the full rated duration. This lets the charge controller register the new cell capacity and confirms the cell accepts load 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\"\u003eNi-CD cells lose voltage during storage. If the cell voltage on arrival sits outside the charge controller's float acceptance window, the controller flags a fault instead of entering normal charge mode. This is not a faulty battery or a faulty fitting. Leave the fitting powered for 12–24 hours — the controller will trickle-charge the cell up to the acceptance threshold and switch to green once voltage reaches approximately 5.4–5.6V across the pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light dims and cuts short during the duration test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell installed without a conditioning cycle will not deliver its full 4000mAh on first activation. The charge controller hasn't yet logged a complete charge-discharge reference for the new cell, so available capacity is lower than rated. The fix is one full charge cycle before the test — at least 24 hours on mains with no activation. After that conditioning cycle, the cell will deliver rated capacity and the light will hold output for the full test duration.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360408666202,"sku":"BWCS-MGN9026LS-1","price":69.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360408698970,"sku":"BWCS-MGN9026LS-2","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360408731738,"sku":"BWCS-MGN9026LS-3","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MGN9026LS-1.webp?v=1778614613","url":"https:\/\/batteryweb.com\/products\/orbik-b17044-replacement-battery-48v-4000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
