It keeps the door controller powered through mains failures, allowing the door to complete its open and close cycles and maintain safety functions. OEM part numbers TO1007, 80100302, ATD007, 300011, and MGN0208 all cross-reference to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eES90, ES100, ADT006, ADT007 fitment:\u003c\/strong\u003e\n    These Dorma controllers share the same 9.6V backup rail, connector pinout, and BMS handshake protocol. One cell covers the entire group — no wiring modification required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through simulated mains-fail events on the ES90 platform. The BMS held voltage above the controller's low-voltage cutoff and did not trip during a full open-and-close cycle under motor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install power-fail verification:\u003c\/strong\u003e\n    After fitting, manually trigger a power-fail test during a low-traffic period. Automatic door backup batteries must prove they can complete a full door cycle under motor load before the door returns to normal service — 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 its programming after a power outage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ES90 and ES100 store open-speed, close-speed, and hold-time parameters in volatile RAM. That RAM relies on the backup battery to retain its contents when mains power drops. A depleted or failed backup cell means those settings vanish the moment power cuts out. If your controller keeps reverting to factory defaults after outages, replace the backup battery before reprogramming — otherwise the settings will be lost again at the next interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDoor moving noticeably slower during a backup power event\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dorma controller deliberately reduces motor drive current when running on battery backup — this is a firmware-level load management behaviour, not a fault. The door will open and close more slowly than on mains power to protect the backup cell from rapid discharge. If the door is slower than usual but still completes a full cycle, the battery and controller are functioning correctly. If the door stalls mid-cycle or reverses unexpectedly, check the backup battery voltage under load — it should hold above 8.4V during motor operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315053559898,"sku":"BWCS-DRS900SL-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315053592666,"sku":"BWCS-DRS900SL-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315053625434,"sku":"BWCS-DRS900SL-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRS900SL-1.webp?v=1777949402","url":"https:\/\/batteryweb.com\/products\/dorma-es90-replacement-battery-96v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
