It powers the backup circuit that keeps the door operational when mains power is lost. Dimensions are 97.50 × 70.80 × 28.80mm — verify fit before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRecord 80100503 backup system:\u003c\/strong\u003e\n    The 80100503 controller runs its backup circuit on a dedicated Ni-MH pack at 24V. When mains power drops, the controller switches to this battery to complete door cycles and hold programming in volatile RAM. A degraded cell causes both failures simultaneously.\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 cleanly to the backup circuit. Cell balance held across a full charge-discharge cycle at 1500mAh rated capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install power-fail test:\u003c\/strong\u003e\n    After fitting this battery, trigger a manual mains-fail test during a low-traffic period. Automatic door backup batteries must complete at least one full door cycle under load to confirm the replacement is working before the building relies on 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  \u003cp class=\"bpw-desc-p\"\u003eWhen the 80100503 switches to battery, it draws peak current at motor start — this is the hardest point for a degraded Ni-MH pack. If the door stalls mid-cycle or resets, the battery voltage is collapsing under that initial load spike. A healthy pack at full charge should hold above 21.6V during motor start. Charge the replacement for a full 24 hours before the first power-fail test, then check voltage under load at the battery terminals.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eController losing door programming after a power outage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 80100503 stores its configuration in volatile RAM backed directly by this battery. If the backup battery is depleted when mains power fails, the controller loses its door travel limits, speed settings, and hold-open timing. This looks like a controller fault but the actual cause is a dead or deeply discharged backup cell. Recharge or replace the battery, then reprogram the controller from scratch using the commissioning procedure in the Record installation manual.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315053756506,"sku":"BWCS-RST801AF-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315053789274,"sku":"BWCS-RST801AF-2","price":94.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315053822042,"sku":"BWCS-RST801AF-3","price":104.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RST801AF-1.webp?v=1777949431","url":"https:\/\/batteryweb.com\/products\/record-80100503-replacement-battery-24v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
