It fits the WALYNX-RCHB-SC, Lynx Alarm Security Panel, Safewatch QuickConnect Plus, and QuickConnect Security System. Swap it when your panel flags a persistent low-battery fault or fails to hold charge away from the dock.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLynx touchscreen platform compatibility:\u003c\/strong\u003e\n    These models share the same 7.2V two-cell Ni-MH pack format, dock connector pin-out, and panel BMS charge profile. One battery fits the full range without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Lynx panel's charge cycle and confirmed the BMS accepted the pack without throwing a tamper or fault code. Charge current stabilised at float within the expected window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation charge conditioning:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after fitting this cell. The panel BMS needs 24–48 hours at float charge before it can report an accurate battery state. Testing before that window will trigger a false low-battery alert on the keypad.\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 new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Lynx panel's BMS does not read a fresh Ni-MH pack as full on day one. It runs a charge-acceptance check over the first 24–48 hours and will flag low battery until that cycle completes. This is a BMS behaviour, not a fault with the cell. Leave the panel on mains power and connected to the dock for at least 48 hours before drawing any conclusions about battery status.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePanel losing zone programming during a mains power outage after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the new cell has not yet completed its initial 48-hour conditioning cycle, the panel may not draw enough current from the pack to sustain memory during a mains outage. The voltage is present but the BMS has not yet confirmed the cell as a valid backup source. To avoid losing programming, keep the panel on mains for two full days after fitting the battery before any power interruption occurs. If programming is already lost, restore it via the installer code menu at the keypad.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309835812954,"sku":"BWCS-HYL300BT-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309835845722,"sku":"BWCS-HYL300BT-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309835878490,"sku":"BWCS-HYL300BT-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYL300BT-1.webp?v=1777868260","url":"https:\/\/batteryweb.com\/products\/adt-walynx-rchb-sc-replacement-battery-72v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
