It sits in the backup circuit and powers the door mechanism when mains supply drops. Capacity is 1600mAh — 13.44Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSTA13, STA14, and PS131 compatibility:\u003c\/strong\u003e\n    These three operators share the same backup battery bay, connector pinout, and 8.4V charging rail. The NC700AA part number covers all three — no wiring changes needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on the backup circuit. The BMS accepted charge correctly and held voltage above the low-battery cutoff through a full simulated door cycle under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation test requirement:\u003c\/strong\u003e\n    After fitting the new battery, manually trigger a power-fail test during a quiet period. Backup batteries in door operators must prove they can complete a full open-and-close cycle under real motor load before you rely on them in operation.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDoor controller losing stored programming after a power outage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe STA13 and STA14 store door parameters — open speed, hold-open time, obstacle sensitivity — in volatile RAM. That RAM is kept alive by the backup battery when mains power cuts. If the battery is depleted below its retention threshold, even a brief outage wipes the controller's settings. You come back to a door that either won't move or behaves erratically. Replace the battery and allow a full 24-hour charge before the next power interruption to restore programming protection.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery backup not activating when mains power fails\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the door goes dead during a mains failure instead of switching to battery, the backup circuit is not seeing sufficient voltage from the NC700AA. Ni-MH cells self-discharge over time — a battery left uncharged for several months can drop below the activation threshold of the backup relay. Check terminal voltage with a multimeter; a healthy charged NC700AA should read at least 8.0V at rest. If it reads below 7.5V, the battery won't trigger the backup circuit and must be replaced.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315054575706,"sku":"BWCS-RST130AF-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315054608474,"sku":"BWCS-RST130AF-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315054641242,"sku":"BWCS-RST130AF-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RST130AF-1.webp?v=1777949432","url":"https:\/\/batteryweb.com\/products\/record-sta13-replacement-battery-84v-1600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
