It slots into the door controller's backup circuit and takes over when mains power drops. Capacity matches the original at 2000mAh (24Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSTA15 and ATRE021 compatibility:\u003c\/strong\u003e\n    Both models share the same 12V backup rail, connector footprint, and BMS handshake protocol — one battery covers both. The OEM part numbers 013.508.000E-C and 80100501 confirm fitment across that platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through a simulated mains-fail event on the STA15 controller. The BMS engaged cleanly, the backup circuit activated without fault codes, and the door completed a full open-close cycle under motor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install power-fail test:\u003c\/strong\u003e\n    After fitting, trigger a manual mains-fail test during a quiet period. Automatic door backup batteries must prove they can drive a full door cycle under load before the installation is signed off — do not skip this step.\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 saved programming after a power outage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe STA15 stores its opening parameters — travel limits, obstacle sensitivity, hold-open timers — in volatile RAM. That RAM requires a live backup battery to retain data when mains power drops. A depleted or failed backup battery means the controller resets to factory defaults every time power cuts out. If the door is asking for reconfiguration after every outage, replace the backup battery and recharge it for 24 hours before the next test.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBackup circuit not activating during mains failure\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the door goes completely dead on a mains failure instead of switching to battery backup, the controller's transfer relay is likely not seeing sufficient voltage from the backup battery to trigger. Ni-MH cells in standby applications self-discharge over months, and a battery sitting below approximately 10.5V will not satisfy the relay's activation threshold. Charge the battery fully — allow at least 24 hours on the controller's trickle circuit — then simulate a mains cut to confirm the relay trips correctly. If voltage still reads below 11V after a full charge cycle, the cells have degraded and the battery needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315054379098,"sku":"BWCS-RST150AF-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315054411866,"sku":"BWCS-RST150AF-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315054444634,"sku":"BWCS-RST150AF-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RST150AF-1.webp?v=1777949432","url":"https:\/\/batteryweb.com\/products\/record-sta15-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
