It keeps wireless alarm components operational during mains power loss. Capacity is 700mAh (6.72Wh) — matching the original OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRadio Channel and LS-30 compatibility:\u003c\/strong\u003e\n    These models share a common 9.6V backup rail and the same connector footprint. The eight-cell NiMH stack matches the voltage sequencing the panel BMS expects at startup. Any mismatch here causes the panel to reject the cell and report a fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the LS-30 charge management circuit. The BMS accepted the cell without fault codes, completed the float-charge cycle, and held the rated voltage under simulated zone-trigger load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install float charge period:\u003c\/strong\u003e\n    Do not run a zone diagnostic immediately after fitting this cell. The LS-30 panel requires 24–48 hours on float charge before its BMS registers the battery as full. Testing before that window ends will trigger a false low-battery report on the panel display.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the LS-30 panel shows low battery hours after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LS-30 uses a float-charge monitoring loop that reads accumulated charge current, not just terminal voltage. A brand-new cell starts with low accumulated charge, so the panel flags low battery even if the resting voltage looks correct on a meter. This is not a fault with the cell — it is the panel's BMS working as intended. Leave the panel on mains power for 48 hours and the low-battery indicator will clear without any reset procedure.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSiren does not sound during a test cycle after backup battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LS-30 siren circuit draws a short high-current burst at trigger. If the backup cell has not completed its initial charge stabilisation, the panel suppresses the siren output to protect the cell from a deep-discharge event on the first draw. This typically resolves after 30–60 minutes on float charge following installation. Run the test cycle only after the panel's charge indicator shows full — if the siren still does not activate, confirm mains power is present and the panel is not in walk-test inhibit mode.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309814546522,"sku":"BWCS-LFP300BT-1","price":43.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43309814579290,"sku":"BWCS-LFP300BT-2","price":51.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43309814612058,"sku":"BWCS-LFP300BT-3","price":56.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LFP300BT-1.webp?v=1777868262","url":"https:\/\/batteryweb.com\/products\/lifesos-radio-channel-replacement-battery-96v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
