When mains power fails, this battery keeps the door operator running so the door can complete its open or close cycle. Capacity is 38.4Wh as rated by the manufacturer.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSTG19, STM 21, and BAT 19 compatibility:\u003c\/strong\u003e\n    These three Record door operator models share the same 19.2V battery rail, connector format, and BMS communication protocol — one cell pack covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated mains-fail events and confirmed the BMS hands off to battery backup without trip delay, completing a full door open-and-close cycle under load each time.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install verification:\u003c\/strong\u003e\n    After installing the backup battery, manually trigger a power-fail test during a low-traffic period — Record door backup batteries must be tested at installation to confirm they can complete a full door cycle under real motor load before the site returns to normal operation.\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\"\u003eThe Record STG19 controller monitors battery voltage during the motor-start surge. If voltage sags below the controller's cutoff threshold at that surge point, the controller halts the cycle mid-stroke as a protection measure. A partially degraded Ni-MH pack may read 19.2V at rest but collapse under load. A fresh replacement pack should hold above 17V during the motor-start draw to allow a full cycle to complete.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDoor controller losing its programmed settings after a mains outage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe STG19 controller stores timing, force, and access settings in volatile RAM backed continuously by the backup battery. If that battery has depleted through self-discharge or age, even a brief mains interruption wipes those settings. This failure is separate from whether the door moves — the door may not move at all after reprogramming is lost. Replace the battery, charge it fully for 24 hours, then re-enter the controller's programming sequence before the next power-fail test.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315052544090,"sku":"BWCS-RTS190AF-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315052576858,"sku":"BWCS-RTS190AF-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315052609626,"sku":"BWCS-RTS190AF-3","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTS190AF-1.webp?v=1777949431","url":"https:\/\/batteryweb.com\/products\/record-stg19-replacement-battery-192v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
