It powers the LED lighting circuit and all mirror functions. Fits OEM part numbers 123400 and 413610.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSITIA and FLORIANA platform compatibility:\u003c\/strong\u003e\n    These mirrors share the same 3.6V single-cell architecture, LED driver board, and battery connector pinout. One cell replacement covers the full range listed under OEM part 123400 and 413610.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the SITIA's charging circuit and monitored the LED driver's constant-current output. The BMS held voltage within spec across low, mid, and full-brightness modes without triggering cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge on LED mirrors:\u003c\/strong\u003e\n    After installing, charge fully before first use. The LED driver calibrates its constant-current output against cell voltage on that first full charge. A partially charged cell at install can cause uneven brightness across the LED ring on the first session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy BRAVAT mirrors dim before the low-battery indicator triggers\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe LED driver in these mirrors uses a constant-current circuit that reduces output current as cell voltage sags below roughly 3.2V. The battery indicator, however, only triggers at a lower voltage threshold — often around 3.0V. That gap means visible dimming can begin well before any low-battery warning appears. A degraded Ni-MH cell that cannot hold voltage under LED load will show this symptom early in a charge cycle. Replacing the cell restores the driver's ability to sustain rated current at full brightness.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMirror not charging via USB after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SITIA's USB charging circuit requires a clean 5V input at sufficient current — most issues trace back to a low-output USB port or a cable with high resistance drop. After swapping the battery, the new cell's lower resting voltage can make a marginal charger appear to work but deliver too little current to actually charge the cell. Check the adapter is rated at 1A or above, not a low-output PC USB port. If charging still fails, measure input voltage at the mirror's port — it should read at least 4.8V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340114264154,"sku":"BWCS-BRT400SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340114296922,"sku":"BWCS-BRT400SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340114329690,"sku":"BWCS-BRT400SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BRT400SL-1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/bravat-sitia-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
