It fits directly into the luminaire's battery bay and connects to the onboard charge controller. Capacity is 1800mAh (5.76Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eALMAAZ luminaire compatibility:\u003c\/strong\u003e\n    The ALMAAZ series uses a single LiFePO4 cell at 3.2V nominal. The charge controller is calibrated for LiFePO4 float voltage — substituting a NiMH or Li-ion cell of similar physical size will trigger a persistent fault condition because the float thresholds do not match.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a simulated mains-failure activation on compatible emergency lighting hardware. The BMS held load without voltage sag below the luminaire's cutoff threshold, and the charge controller transitioned from bulk charge to float without faults.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle test requirement:\u003c\/strong\u003e\n    Within 24 hours of installation, hold the luminaire's test button for the full rated duration. This allows the charge controller to register the new cell's capacity baseline before your next scheduled compliance inspection — skipping this step can cause a false fail on the duration test.\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 LiFePO4 cell stored at low state of charge can sit below the charge controller's float acceptance window — typically under 2.8V resting. When the controller sees a cell voltage in that range, it holds the fault\/red state rather than entering bulk charge. The fix is to apply a short conditioning charge using a compatible external LiFePO4 charger set to 3.2V before installing the cell. Once resting voltage reaches approximately 3.0V, reinstall the cell and the controller should accept it and transition to bulk charge within a few minutes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency light dims after a few minutes during a duration test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDimming partway through a test means cell voltage is dropping faster than rated — the luminaire's driver throttles output to stay within its input voltage window. On a freshly installed cell, this almost always means the cell has not completed its first full charge cycle from storage. A new LiFePO4 cell needs at least one complete charge-to-float cycle before it delivers full capacity under load. Allow the luminaire 24 hours on mains power after installation, then re-run the duration test. If dimming persists after a confirmed full charge, check the resting voltage — it should sit between 3.2V and 3.3V before the test begins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360421183578,"sku":"BWCS-DKL930LS-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360421216346,"sku":"BWCS-DKL930LS-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360421249114,"sku":"BWCS-DKL930LS-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DKL930LS-1.webp?v=1778614638","url":"https:\/\/batteryweb.com\/products\/deko-light-ceiling-luminaire-almaaz-emergency-luminaire-replacement-battery-32v-1800mah-lifepo4","provider":"BatteryWeb","version":"1.0","type":"link"}
