It fits models 2447-3031-02, 9019673, 2008797, and 9020569. Voltage and cell count match the original pack so the onboard motor controller sees no mismatch on startup.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model compatibility — 2447-3031-02, 9019673, 2008797, 9020569:\u003c\/strong\u003e\n    These four Simu units share the same 10.8V three-cell architecture, connector pinout, and BMS communication protocol. One cell pack covers the full group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through motor-drive and idle states. The BMS held charge across full travel sequences without triggering overcurrent cutoff, and cell balance remained stable through repeated discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install reconnect window:\u003c\/strong\u003e\n    After fitting this battery, leave the blind controller powered on for at least 60 seconds before operating it. Simu smart home units run a mesh network re-join sequence after any power interruption — triggering a travel command before that sequence completes can cause the motor to ignore the first command or log a communication fault.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy Simu blind motors drain batteries faster when network traffic is high\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSimu automated blind systems stay in low-power sleep between commands, but the wireless receiver wakes on every polling ping from the hub. If your smart home hub is set to poll devices frequently — every 30 seconds or less — the receiver wakes dozens of times per hour. That duty cycle adds up fast and the cell depletes well ahead of its rated capacity. Check your hub's polling interval and set it to 5 minutes or longer for blinds that don't need real-time position feedback.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alert fires immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when a replacement pack has been sitting in storage and its resting voltage has dropped below the alert threshold the controller uses — typically around 10.0V for a 10.8V nominal pack. The controller reads the cell voltage on first boot and flags it before the pack has had any chance to recover. Connect the unit to its charging source and allow a full charge cycle to complete. Once the pack reaches 12.6V, the alert clears and the controller resumes normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416142610522,"sku":"BWCS-BHC520AF-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416142643290,"sku":"BWCS-BHC520AF-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416142676058,"sku":"BWCS-BHC520AF-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BHC520AF-1.webp?v=1779760467","url":"https:\/\/batteryweb.com\/products\/simu-2447-3031-02-replacement-battery-108v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
