It holds the panel live during mains outages so zones, sirens, and monitoring communication stay active. Voltage and capacity match the original 228844 cell exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGo Control and GC2 series compatibility:\u003c\/strong\u003e\n    These panels share the same 7.2V battery bay, connector pinout, and charge management circuit. The BMS in each model accepts the same float voltage, so one cell fits the full GC2 family without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a GC2e panel under simulated mains loss. The BMS accepted the charge cycle without fault codes, held the panel at normal operating voltage, and released the low-battery alert after the float charge completed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation charge cycle on alarm panels:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after swapping this cell. The panel needs 24 to 48 hours on mains power to bring the new battery to full float charge. Testing before that window can trigger a false low-battery report from the panel's charge monitor.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm panel reporting low battery hours after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 2GIG Go Control panel measures battery state through a voltage threshold, not a capacity gauge. A brand-new Ni-MH cell straight from storage sits below that threshold until the onboard charger has run a full float cycle. That cycle takes 24 to 48 hours on uninterrupted mains power. The panel clears the low-battery condition automatically once the cell crosses the target voltage — no manual reset is required.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePanel loses zone programming during a power outage after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel drops its programming during an outage, the backup battery was not yet accepted before mains power failed. The GC2 and GC2e hold configuration in RAM that the battery must sustain — if the cell voltage is still in the initial charge phase, it may not deliver enough current to keep RAM alive under load. Install the new cell and leave the panel on mains for a full 48 hours before the next outage test. A fully conditioned cell holds the panel above the RAM-sustain threshold of approximately 6.0V throughout a normal outage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309834666074,"sku":"BWCS-ALM844BT-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309834698842,"sku":"BWCS-ALM844BT-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309834731610,"sku":"BWCS-ALM844BT-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ALM844BT-1.webp?v=1777868134","url":"https:\/\/batteryweb.com\/products\/2gig-go-control-panels-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
