It maintains alarm panel operation and preserves system settings when mains power is interrupted. Cross-references OEM part numbers 0-9912-J, GP250BVH6AMX, and PCL00216.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMCS-700, MCS-710, MCS-720 and Bell Box compatibility:\u003c\/strong\u003e\n    These units share the same 7.2V backup rail, physical cell footprint (40 × 27 × 25.60mm), and connector pinout. One replacement cell covers all four devices 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 charge acceptance and BMS handshake on a PowerMax panel. The internal protection circuit accepted charge from the first cycle and the panel cleared the low-battery flag within 36 hours at float.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation charging window:\u003c\/strong\u003e\n    Do not run a zone diagnostic or siren test immediately after fitting this cell. The panel needs 24–48 hours at float charge before its internal voltage threshold registers a full backup battery. Testing before that window 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\"\u003eAlarm panel showing low battery hours after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PowerMax panel does not report a full backup battery based on voltage alone — it monitors the cell across a float-charge window. A fresh Ni-MH cell can sit at 7.0–7.1V on a meter but still read as low on the panel because the BMS has not yet logged enough charge cycles. This is not a fault with the cell. Leave the panel powered on mains for 24–48 hours and the low-battery indicator will clear automatically once the threshold is met.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm losing programming during a mains outage after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel loses zone settings or user codes during a power cut, the backup cell has not yet been accepted by the panel's charge management circuit. This typically happens when the panel is tested or power-cycled within hours of a battery swap, before the cell has completed its initial conditioning charge. The fix is straightforward: restore mains power, leave the panel running undisturbed for 48 hours, then simulate an outage. At that point the cell should sustain panel memory through a standard outage at or above 6.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309830373466,"sku":"BWCS-VPX700BT-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309830406234,"sku":"BWCS-VPX700BT-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309830439002,"sku":"BWCS-VPX700BT-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VPX700BT-1.webp?v=1777868465","url":"https:\/\/batteryweb.com\/products\/visonic-powermax-mcs-700-replacement-battery-72v-230mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
