It fits commercial automatic door operators using OEM part numbers 198015, 80100303, 300012, and 116479. The battery sustains door operation and controller logic during mains interruptions in commercial entry and exit applications.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTürsteuerung backup circuit compatibility:\u003c\/strong\u003e\n    These OEM part numbers cross-reference to the same 19.2V Ni-MH cell stack used across Dorma's automatic door controller range. The voltage rail and connector match the original backup circuit board, so no wiring modifications are needed during swap-out.\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. The BMS handed off cleanly to the backup circuit, the door completed a full open-and-close cycle under motor load, and the controller retained its programmed parameters throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation load test:\u003c\/strong\u003e\n    After fitting, manually trigger a power-fail simulation during a low-traffic period. Automatic door backup batteries must prove they can drive a full door cycle under motor load before going into live service — do not assume the battery is ready without testing it.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAutomatic door not completing full open cycle on battery backup\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a Dorma Türsteuerung door stalls mid-cycle during a mains failure, the most common cause is a partially charged backup battery that cannot sustain the current draw of the door motor through a full stroke. Ni-MH cells have a steeper voltage curve under load than the original charge reading suggests — a cell showing 19.2V at rest can sag below the controller's cutoff threshold the moment the motor engages. A fresh replacement battery needs a full 24-hour charge on the door controller before it can reliably complete a cycle. After charging, test by cutting mains power and cycling the door fully — if it completes, the backup circuit is live.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDoor controller losing its programmed settings after every power outage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Türsteuerung controller stores door parameters — open speed, hold-open time, obstacle sensitivity — in volatile RAM that depends on the backup battery for retention during mains loss. If those settings reset to factory defaults every time power drops, the backup battery is too depleted to hold the RAM supply rail. This is distinct from the door-cycle failure above: the door may open and close fine on mains power, but the controller loses memory the moment mains drops. Replace the battery, charge it fully, and confirm retention by cutting mains for 30 seconds — settings should survive intact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315054051418,"sku":"BWCS-DRM198SL-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315054084186,"sku":"BWCS-DRM198SL-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315054116954,"sku":"BWCS-DRM198SL-3","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DRM198SL-1.webp?v=1777949401","url":"https:\/\/batteryweb.com\/products\/dorma-tursteuerung-replacement-battery-192v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
