It fits the ECturn automatic door operator used in commercial buildings. When mains power fails, this battery keeps the door mechanism operational for emergency egress.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eECturn platform fit:\u003c\/strong\u003e\n    The ECturn uses a dedicated 19.2V Ni-MH battery pack with a specific connector and cell count to match the controller's backup circuit voltage rail. Substituting a different voltage or chemistry causes the backup circuit to reject the pack or fail to charge it correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the ECturn backup circuit and confirmed the BMS accepted the charge handshake, held voltage above the controller's cutoff threshold, and completed a full door-open cycle under motor load without triggering an undervoltage fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install verification:\u003c\/strong\u003e\n    After installing the battery, manually trigger a simulated power-fail test during a low-traffic period. Automatic door backup batteries must be verified at installation — a battery that sits uncharged for weeks before testing may not complete a full door cycle under load when it counts.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eECturn door not completing full open cycle on battery backup\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECturn motor draws a significant current spike at the start of each open cycle. If the backup battery is partially discharged, its voltage sags under that initial motor-start load and the controller interprets it as an undervoltage condition, stopping the door mid-cycle. Ni-MH cells are particularly sensitive to this after sitting in a partially depleted state for extended periods. A new battery should be charged for a full 24 hours before any power-fail test to ensure the cells reach their rated 19.2V resting voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eECturn controller losing door programming after a power outage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECturn stores its door parameters — open speed, hold-open time, and force limits — in volatile memory backed by this battery. When the backup battery is fully depleted, that memory loses power during a mains failure and the controller resets to factory defaults. The door may then move at incorrect speed or fail safety force checks. After fitting a fresh battery, restore the controller settings via the GEZE commissioning tool and confirm the programmed values are retained through a second simulated power-fail cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315052937306,"sku":"BWCS-GEC473AF-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315052970074,"sku":"BWCS-GEC473AF-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315053002842,"sku":"BWCS-GEC473AF-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GEC473AF-1.webp?v=1777949402","url":"https:\/\/batteryweb.com\/products\/geze-ecturn-replacement-battery-192v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
