It fits OEM part numbers 60AAAH6BMJ and 802306063H. When mains power drops, this cell keeps the panel live and monitoring.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHSA6400 and HSA6410 platform fit:\u003c\/strong\u003e\n    These panels share the same 7.2V battery bay, connector, and BMS handshake. One cell covers the full HSA6400 Premium and HSA6410 Easy Fit and Easy EF range without any wiring modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the panel's own BMS. The cell accepted float charge correctly, and the BMS cleared the low-battery flag after the conditioning window completed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install conditioning:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after fitting this cell. Allow 24–48 hours on mains power so the panel can bring the battery to full float charge. Running a diagnostic before that window closes will trigger a low-battery report even on a healthy new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm panel losing programming during a power outage after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe HSA6400 BMS will not commit fully to a new cell until it has completed at least one 48-hour float-charge cycle on mains. If the mains drops before that cycle finishes, the panel may draw more current than the partially charged cell can sustain, causing a voltage collapse that wipes volatile memory. This is not a faulty battery — it is an incomplete acceptance cycle. Restore mains, leave the panel connected for 48 hours, then pull the mains briefly to confirm the cell holds the panel steady above 6.5V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePanel showing low battery fault hours after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA low-battery flag appearing within the first day after installation almost always means the BMS has not yet completed its float-charge assessment — not that the cell is defective. Ni-MH cells ship in a partially discharged state to comply with transport regulations, so the panel sees a resting voltage below its threshold on first check. Leave the panel on mains for a full 24–48 hours. If the fault clears after that window, the cell is functioning correctly. If the flag persists beyond 48 hours, check that the connector is fully seated and that cell voltage at the terminals reads at least 7.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309831028826,"sku":"BWCS-HSA640BT-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309831061594,"sku":"BWCS-HSA640BT-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309831094362,"sku":"BWCS-HSA640BT-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HSA640BT-1.webp?v=1777868235","url":"https:\/\/batteryweb.com\/products\/yale-hsa6400-premium-alarm-control-panel-replacement-battery-72v-800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
